[Evaluation of nasolacrimal duct function in chronic paranasal sinus infections with 99mTc dacryoscintigraphy].

BACKGROUND: Paranasal sinus infections and nasolacrimal duct obstructions are commonly encountered problems. However the relationship between these two conditions is not yet clear. Trauma, surgery, tumors, and systemic diseases are among the causes of acquired nasolacrimal duct obstructions but most of the cases are idiopathic. In this study patients diagnosed with chronic paranasal sinus infection were examined with 99mTc lacrimal dacryoscintigraphy to assess their nasolacrimal duct function. METHODS: Twenty-four patients diagnosed with chronic paranasal sinus infection are included in the study. These patients were observed for at least three months awaiting surgical treatment following unsuccessful medical treatment. The control group included 16 persons admitted to the ophthalmology department without any nasolacrimal duct disease. Nasal endoscopy and paranasal sinus CT revealed normal findings. The age of the patients with chronic paranasal sinus infection and examined in regard to nasolacrimal duct function was between 15 to 17 with a mean age of 34.2 years. Fourteen patients were male and 10 patients were female. The control group included 9 male and 7 female patients between 18 to 60 years with a mean of 30.5 years. RESULTS: The dacryoscintigraphic examination of 48 nasolacrimal ducts in 24 patients with chronic paranasal sinus infection revealed 7 complete and 18 partial obstructions of the duct, and 23 normal findings. In the control group with 32 nasolacrimal ducts of 16 patients, there was no complete obstruction. Partial obstruction (10.6, 12.0, 14.7 minutes) was be observed in three cases. The statistical workup resulted in a significant difference between paranasal sinus patients and control group (x2 = 15,840 p < 0.001). The paranasal sinus CTs of the patients with paranasal sinus disease were staged using the Lund-Mackay staging system: There is no correlation between the staging score of the paranasal sinus infection and the degree of the obstruction the nasolacrimal duct. CONCLUSION: This study shows that chronic paranasal sinus disease plays an important role in the pathogenesis of nasolacrimal duct obstructions. The presence of infection has an influence on the nasolacrimal drainage system, but the distribution (staging) of the infection does not appear to correlate with the degree of nasolacrimal duct obstruction. Partial obstruction cases that may progress to complete obstruction may be detected by dacryoscintigraphy, and the treatment of chronic paranasal sinus disease may help to overcome the lacrimal drainage problems in these cases.

[The maxillary sinus and its illness in the history of rhinology. Images from the history of otorhinolaryngology, highlighted by instruments from the collection of the German Medical History Museum in Ingolstadt].

BACKGROUND ANATOMY: In ancient times the paranasal sinuses, without any anatomical differentiation, were thought to be a system of hollow spaces through which mucus produced by the brain was drained. Leonardo da Vinci in Milano in 1489 was the first to prepare and draw anatomical specimens of the paranasal sinuses; the drawings, however, only became accessible to scientific evaluation as late as 1901. N. Highmore in England in 1651 presented the first detailed description and drawing of the maxillary sinus, and hence it is named Highmore's antrum. C. V. Schneider in Wittenberg, Germany, in 1660 realized that the mucus is not a product of the brain but is produced by the mucous lining of the region itself. F. G. J. Henle in Berlin in 1841 differentiated between various epithelia and described the special function of the ciliated epithelium of the respiratory tract. FROM OZENA TO SINUSITIS: In ancient times the word ozena originally denoted any kind of foul breath, but in the 1st and 2nd century AD (Celsus, Galenus) the term became restricted to foul odor coming from the nose. J. Drake and W. Cowper in England in 1707 reported that in some cases ozena was due to suppuration in the maxillary sinus and could be cured by extraction of a tooth and opening the sinus via the alveolus. L. H. Runge in Rinteln, Germany in 1750 compiled a nearly complete systematic survey of all diseases localized in the maxillary sinus. EARLY STAGES OF SURGERY: A. L. B. B. Jourdain in France in 1765 tried to cure suppurations of the maxillary sinus by irrigation via the natural ostium in the middle nasal meatus, however, his method did not meet with approval. L. Lamorier in Montpellier in 1743 opened the maxillary sinus form the buccal cavity, but his paper was only published in 1768. Lamorier's method and opening the sinus via a dental alveolus remained standard procedures for a long time. K. Ziem in Danzig, Germany, in 1886 analyzed 26 cases of chronic suppurations discharging from the nose, among them his own history, and found out that they can originate from different foci and that the treatment must be centered around the relevant focus. CLASSICAL OPERATIVE PROCEDURES: J. Mikulicz-Radecki in Vienna in 1886 was the first to open the maxillary sinus from the inferior nasal meatus. G. W. Caldwell in New York in 1893 published his method: opening the canine fossa wall, removal of the mucous membrane, and opening a window in the lateral wall of the inferior nasal meatus. G. Boenninghaus in Breslau, Germany, in 1896 was the first in Europe to adopt this method, and he modified it by placing a mucosal flap in the window. Unaware of Caldwell's publication, H.-P. Luc in Paris in 1897 reported on his own operative procedure, which in fact was identical to that of Caldwell's. DEVELOPMENT DURING THE LAST 100 YEARS: The operative procedures and especially the preoperative diagnosis were continually improved so that the surgical treatment of chronic suppurations of the maxillary sinus reached a high standard. During the last decades less radical interventions using an endonasal approach by endoscopy have partly superseded the classical procedures. This development is described in great detail with literal quotations of the original papers, anecdotal details, and illustrations.

[Endonasal frontal sinus surgery with permanent implantation of a place holder].

BACKGROUND: Endonasal frontal sinus surgery is well established. It is not yet clear what degree of enlargement of the frontal sinus neoostium is required to achieve permanent drainage or whether stenting improves the results. PATIENTS AND METHODS: Prospective survey with two groups: Group 1. included 10 patients (15 operations) who underwent endonasal sinus surgery because of chronic polypoid sinusitis with stenting of the frontal sinus neoostium for 6 months. Group 2. included 11 patients (21 operations) without stenting. INTERVENTION: Endonasal frontal sinus surgery with extended drainage Draf Type II (NFA II according to May) with (group 1) and without (group 2) long-term stenting of the neoostium for 5 months using a silicone stent. MAIN OUTCOME MEASURE: 12-16 months postoperatively: flexible endoscopy of nose and frontal sinus; computed tomography; magnetic resonance tomography; Wilcoxon-Mann Withney-Test. RESULTS: With stenting: neoostium endoscopically patent in 80% (including 20% with edematous swelling only at the opening to the frontal sinus), occluded by scar tissue in 6.7%, occluded by polyps in 13.3%. Endoscopy and CT/MRT together: normal mucosa and aeration in 93.3%, complete opacification in 6.7%. Without stenting: neoostium endoscopically patent in 33%, occluded by scar tissue in 48%, occluded by polyps in 19%. Endoscopy and CT together: normal mucosa and aeration in 71.4%, aeration and mucosal swelling in 14.3%, complete opacification in 14.3%. With stenting of the frontal sinus neoostium for six months endoscopic evaluation of the frontal sinus was possible in a significantly higher proportion of cases (p = 0.0416). CONCLUSION: Long-term stenting of the frontal sinus significantly reduces the rate of recurrent stenosis of the frontal neoostium and is recommended in all cases where an extended frontal sinus drainage is necessary. The optimal design for such a stent has not yet been clearly defined.

Bacteriological findings in nasopharynx specimens from patients with a clinical diagnosis of acute sinusitis.

OBJECTIVE: To study results from bacteriological specimens from nasopharynx in patients with a clinical diagnosis of acute sinusitis in relation to CT findings. DESIGN: Prospective study. SETTING: Patients from general practice in Vestfold county, Norway. PATIENTS: 427 patients 15 years and older from two studies with a clinical diagnosis of acute sinusitis, and who were examined with coronal CT scans of the paranasal sinuses. Fluid level or total opacification of any sinus was taken as a hallmark of sinusitis. MAIN OUTCOME MEASURES: Bacteriological findings in nasopharynx specimens and proportions of various sinus pathogens in patients with and without sinusitis confirmed by CT. RESULTS: In the study, 252 patients had acute sinusitis and 175 patients did not. In the sinusitis groups, 27% of the patients had Streptococcus pneumonia, 12% had Staphylococcus aureus and 10% had Haemophilus influenzae in their nasopharynx specimens. Forty-five percent of the patients had normal nasal flora or no growth. The strains of Streptococcus pneumonia and Haemophilus influenzae showed high sensitivity to PcV, while the Moraxella strains were resistant to it. CONCLUSION: Streptococcus pneumoniae and Haemophilus influenzae were the most frequent sinus pathogens found in the nasopharynx specimens, and they were significantly more frequent in the group with confirmed sinusitis. The proportion of specimens with normal nasal flora or no growth was significantly higher in the non-sinusitis group.

Fungal sinusitis in the immunocompetent patient: risk factors and surgical management.

BACKGROUND: Fungal sinusitis has been reported increasingly in immunocompetent patients. However, the most effective, appropriate mode of therapy has not been determined. MATERIALS AND METHODS: In this retrospective study, we examined the records of 110 immunocompetent patients with chronic sinusitis who had undergone sinus surgery at our institution between 1983 and 1994. Five patients (4.5%) with fungal sinusitis were identified. Information on those patients was compared with that of the 105 patients with nonfungal sinusitis. RESULTS: Prolonged use of topical steroids was no more common in patients with fungal sinusitis (20%) than it was in patients with nonfungal sinusitis (4.8%) (p = 0.25). Differentiating features of fungal sinusitis were the presence of a metallic density and areas of high- and low-density on radiologic examination (p < 0.01). All five of the patients with fungal sinusitis were cured by surgical intervention, primarily endoscopic sinus surgery, without undergoing anti-mycotic therapy. Four of the five patients were followed up for at least 3 years without any recurrence. CONCLUSION: Endoscopic sinus surgery is and should remain the mainstay of treatment for fungal sinusitis in immunocompetent patients. Adjunctive anti-mycotic therapy may not be necessary.

Role of local immunoglobulin E production in the pathophysiology of noninvasive fungal sinusitis.

OBJECTIVES/HYPOTHESIS: Immunoglobulin (Ig)E-mediated hypersensitivity to fungi has been postulated to explain allergic fungal sinusitis (AFS). Not all patients suspected to have AFS demonstrate systemic evidence of allergy. Locally produced IgE might explain those patients with no systemic evidence of allergy but clinical features of AFS. The aim was to determine whether fungal-specific IgE could be demonstrated in sinus mucin in patients with eosinophilic mucin rhino-sinusitis. STUDY DESIGN: A prospective study was undertaken in a tertiary rhinology practice in Adelaide, South Australia. METHODS: : Eighty-six consecutive patients with nasal polyposis and thick, colored macroscopically "fungal-like" sinus mucin at time of surgery for chronic sinusitis were entered in the study. The sinus mucin was liquefied and underwent testing for fungal-specific IgE (Pharmacia UniCAP) and fungal culture. Serum fungal-specific and total IgE, eosinophil count, C-reactive protein (CRP), and eosinophilic cationic protein (ECP) were measured. RESULTS: Fifty-six (65%) patients were fungal culture positive, and 37% had a detectable fungal-specific IgE in sinus mucin. Data were available to classify 81 patients: AFS = 24 (30%), AFS-like = 6 (7%), nonallergic eosinophilic fungal sinusitis = 32 (40%), nonallergic, nonfungal eosinophilic sinusitis = 19 (23%). Patients with AFS were significantly more likely to have fungal-specific IgE in sinus mucin (17/24, 71%, P =.02). In all fungal culture-positive patients, positive mucin fungal-specific IgE was significantly associated with systemic fungal allergy (P =.005), but a raised total serum IgE was not. Six (19%) of the 32 patients with positive fungal cultures but negative serum fungal-specific IgE had a positive mucin fungal-specific IgE, suggesting that they may be reclassified as AFS. The mean ECP and total IgE were raised most significantly in the AFS subgroup. CONCLUSIONS: This is the first study to show that fungal-specific IgE may be demonstrated in sinus mucin. It was significantly associated with systemic fungal allergy and may play a role in a minority of fungal sinusitis patients in the absence of systemic fungal allergy.

Relationship between atrial conduction defects and fractionated atrial endocardial electrograms in patients with sick sinus syndrome.

The relationship between abnormal atrial electrograms (AAE) recorded during sinus rhythm by endocardial catheter mapping of the right atrium and the atrial conduction defects of sinus impulses or single atrial extrastimuli was investigated in 44 patients with sick sinus syndrome. The patients were divided into two groups on the basis of the presence (n = 29) or absence (n = 15) of AAE recorded during sinus rhythm. The P wave duration in the AAE (+) Group patients was 137 +/- 14 msec, and 125 +/- 15 msec in the AAE (-) Group; P < 0.02. The intraatrial conduction time of sinus impulses in the AAE (+) Group was 54 +/- 12 msec, and 39 +/- 9 msec in the AAE (-) Group; P < 0.001. The interatrial conduction time in the AAE (+) Group was 101 +/- 14 msec, and 78 +/- 16 msec in the AAE (-) Group; P < 0.001. In the AAE (+) Group, 11 (38%) patients had a sinus node recovery time > 4 seconds, whereas in the AAE (-) Group there was only one (6%) patient; P < 0.03. AAE showed a specificity of 93% and a positive predictive accuracy of 91% in predicting inducibility of atrial fibrillation. The sensitivity was 35% and the negative predictive accuracy was 42%. Sustained atrial fibrillation was induced in ten (35%) patients of the AAE (+) Group, and in one (7%) patient of the AAE (-) Group; P < 0.05. These data suggest that in patients with sick sinus syndrome who possess abnormal endocardial electrograms in sinus rhythm within the right atrium have: (1) a significantly longer P wave duration; (2) a significantly longer intraatrial and interatrial conduction time of sinus impulses; and (3) a significantly greater sinus node dysfunction and higher incidence of induction of sustained atrial fibrillation. It is concluded that there are significantly greater atrial conduction defects in patients with sick sinus syndrome who possess AAE within the right atrium during sinus rhythm.

Petrosal sinus sampling: technique and rationale.

Bilateral simultaneous sampling of the inferior petrosal sinuses is an extremely sensitive, specific, and accurate test for diagnosing Cushing disease and distinguishing between that entity and the ectopic ACTH syndrome. It is also valuable for lateralizing small hormone-producing adenomas within the pituitary gland. The inferior petrosal sinuses connect the cavernous sinuses with the ipsilateral internal jugular veins. The anatomy of the anastomoses between the inferior petrosal sinus, the internal jugular vein, and the venous plexuses at the base of the skull varies, but it is almost always possible to catheterize the inferior petrosal sinus. In addition, variations in size and anatomy are often present between the two inferior petrosal sinuses in a patient. Advance preparation is required for petrosal sinus sampling. Teamwork is a critical element, and each member of the staff should know what he or she will be doing during the procedure. The samples must be properly labeled, processed, and stored. Specific needles, guide wires, and catheters are recommended for this procedure. The procedure is performed with specific attention to the three areas of potential technical difficulty: catheterization of the common femoral veins, crossing the valve at the base of the left internal jugular vein, and selective catheterization of the inferior petrosal sinuses. There are specific methods for dealing with each of these areas. The sine qua non of correct catheter position in the inferior petrosal sinus is demonstration of reflux of contrast material into the ipsilateral cavernous sinus. Images must always be obtained to document correct catheter position. Special attention must be paid to two points to prevent potential complications: The patient must be given an adequate dose of heparin, and injection of contrast material into the inferior petrosal sinuses and surrounding veins must be done gently and carefully. When the procedure is performed as outlined, both inferior petrosal sinuses can be catheterized in more than 98% of patients. The complication rate is low, and the theoretical risk of major morbidity or death is less than 1% (neither has yet occurred, to our knowledge). The most common complication is groin hematoma.

Interaction of right and left carotid sinus baroreflexes in the dog.

Carotid sinus reflex interactions were studied in 10 dogs anesthetized with pentobarbital sodium. The right and left carotid sinus regions were isolated and perfused at controlled pressures. Pressure in the right and left carotid sinuses were independently varied, and the resulting steady-state reflex changes in arterial pressure, heart rate, respiratory frequency, tidal volume, and total ventilation were measured. Reflex changes when carotid sinus pressure was changed on one side were strongly influenced by pressure in the contralateral carotid sinus (P less than 0.05). Right carotid sinus gain was found to be 0.628 +/- 0.058 at a left carotid sinus pressure of 50 mmHg and 0.148 +/- 0.027 when left carotid sinus pressure was 200 mmHg. Similar results were found for left carotid sinus gain. Suppression was also found for heart rate, respiratory rate, tidal volume, and total ventilation. The hypothesis that rapid resetting of one carotid sinus baroreflex might influence responses from the other side was also tested. Although ipsilateral resetting was consistently observed, no contralateral component of the resetting was detected. An additional inhibitory summation between the right and left carotid sinuses was found such that simultaneous excitation of both receptors resulted in a smaller reflex response than did the sum of individual responses. Sympathetic denervation of the carotid sinus region had no effect.

Endoscopic surgery for mycotic and chronic recurring sinusitis.

Chronic sinusitis and its complications are often caused or perpetuated by fungi. In Europe and North America Aspergillus species are the most common contaminants of the sinuses, with relatively few cases of mycoses caused by Mucor, Candida, Penicillium, Cladosporium, and Fusarium reported in the literature. Although Aspergillus and Mucor are mainly saprophytic, they may cause severe, potentially lethal complications. Consequently, therapy should include complete removal of the mycotic masses and prevention of reinfection. In nearly all cases in our experience, fungal diseases of the maxillary sinuses are secondary diseases, the pathologic conditions for which are created by chronic recurring sinusitis. Nasal endoscopy has shown that in most cases of recurring sinusitis, infection spreads from the nose into the larger sinuses, mostly from an infected anterior ethmoid. Maxillary and frontal sinuses are fully dependent on the pathophysiologic conditions in the anterior ethmoid because their ventilation and drainage pass through its complicated system of fissures and clefts into the middle nasal meatus. Endoscopic endonasal surgery of the diseased ethmoid is therefore an important element in our treatment schedule. Stenotic and/or chronically infected areas of the anterior ethmoid are identified by conventional or computed tomography. These areas then undergo endonasal operation under the guidance of rigid endoscopes. Diseased mucosa is removed, narrow or stenotic areas are widened, and the natural maxillary sinus ostium is enlarged. In many cases it is possible to remove all mycotic masses through this new window. Fenestration into the inferior nasal meatus is unnecessary with this method, and the sinus mucosa is usually left untouched. For follow-up treatment, instillations of antimycotic or antibiotic ointments are used. Even in cases of massive mucosal changes, the dependent sinuses, such as the frontal or maxillary sinuses, usually heal spontaneously after this procedure without having been treated directly. More than 140 patients with mycotic sinusitis, 48 of whom were studied and followed up for this paper, were treated by us during the last 8 years. The endoscopic surgical technique we have developed is described in detail.

Therapeutic approach to sinusitis: antiinfectious therapy as the baseline of management.

Although acute sinusitis is an infectious disease in which several bacterial species play a major etiologic role, there is an important interaction between the respiratory viruses (common cold viruses) and the bacteria in the pathogenesis of acute community-acquired sinusitis. The relative inaccessibility of the sinus cavities makes special techniques of sampling necessary to acquire specimens that accurately reflect disease conditions in the sinuses. Bacterial etiology of sinus infection has therefore been determined by sinus puncture studies, chiefly of the maxillary sinus, several of which are reviewed here. Because the bacteria causing acute sinusitis have not changed in many years, puncture is not often necessary for clinical diagnosis. Patients with acute, community-acquired sinusitis can usually be treated empirically, on the basis of previous studies, unless complications are suspected. In that case, and in other patients with hospital-acquired sinusitis, puncture of the involved sinus and aspiration of sinus fluid for Gram's staining and quantitative microbial cultures and sensitivities are required for appropriate antimicrobial management.

Inferior petrosal sinus arginine vasopressin concentrations in normal volunteers and patients with Cushing's disease.

In patients with Cushing's disease (CD), basal inferior petrosal sinus arginine vasopressin (AVP) concentrations are greater than peripheral levels and are further increased by the administration of CRH. AVP has an interpetrosal sinus gradient similar to that for ACTH, leading to the hypotheses that petrosal sinus AVP might either be derived from the corticotroph adenoma or be important for adenoma formation. To determine whether petrosal sinus AVP is truly increased in patients with CD, we compared inferior petrosal sinus and peripheral venous AVP and ACTH levels in 23 patients with CD and 9 healthy volunteers before and after iv ovine CRH. In both groups, AVP and ACTH showed interpetrosal lateralization, such that greater levels of both hormones were found at each time point in a single dominant petrosal sinus. When both hormones exhibited lateralization (an intersinus gradient > 1.5), ACTH and AVP always lateralized together. In patients with CD, the ACTH interpetrosal sinus lateralization correctly identified the side of the pituitary containing the tumor in 75% of evaluable patients, whereas the AVP interpetrosal sinus lateralization identified 63% (P = NS). Ovine CRH stimulated AVP in both the dominant and nondominant petrosal sinuses in patients with CD. Although basal AVP in the dominant petrosal sinus was not significantly different in patients with CD and normal volunteers (144 +/- 85 vs. 13.0 +/- 4.3 pmol/L; P = 0.058), dominant petrosal sinus AVP was significantly elevated in patients with CD compared to normal volunteers at 3 min (269 +/- 122 vs. 45.1 +/- 30.0 pmol/L; P < 0.05) and 5 min (315 +/- 120 vs 40.2 +/- 23.6 pmol/L; P < 0.05) after ovine CRH administration. Peripheral venous AVP levels were similar in all groups. We conclude that lateralization of AVP secretion occurs in both patients with CD and normal volunteers, but there is greater CRH-stimulated AVP secretion in the inferior petrosal sinuses of patients with CD.

Effects of angioplasty upon carotid sinus mechanical properties and blood pressure control in the dog.

The effects of vein patch angioplasty of the carotid sinus upon carotid sinus control of blood pressure and carotid sinus mechanical properties were studied in nine vagotomized dogs. Pressures in the isolated carotid sinuses were increased from 60 to 180 mm Hg in steps of 30 mm Hg, and the resulting reflex changes in mean aortic pressure were measured both before and after unilateral angioplasty. Angioplasty significantly decreased aortic pressure for carotid sinus pressures above 60 mm Hg, decreased the calculated carotid sinus reflex set point pressure, and increased the range of control of arterial blood pressure together with the maximal capacity of the arterial baroreceptors to effect vasoconstriction. In five dogs, concomitant changes in carotid sinus diameter were measured. From the latter, together with accompanying changes in sinus wall geometry, were calculated the tension-strain modulus of elasticity of the carotid sinus wall, together with the radial displacement of the media-adventitial junction. Calculated increases in the latter were consistent with the observed increased effectiveness of the carotid sinus baroreceptors after angioplasty. It was concluded that the modification of blood pressure and its control was predominantly due to the surgical exaggeration of normal carotid sinus geometry accompanied by modest changes in carotid sinus wall mechanical properties.

Sigmoid sinus thrombosis after closed head injury in children.

In the literature, clinical descriptions of sigmoid sinus thrombosis occurring after closed head injury in children are rare. One to 5 days after trauma to the back of the head, five children (aged 1 to 7 yr) presented with gait ataxia, vomiting, and headache. Trauma was mild in four children. Computed tomography of all the children, performed within 5 days after the injury, showed focal hyperdensity in the region of the left sigmoid sinus. Four children had extra-axial hyperdense collections along the left transverse sinus, and three had skull fractures adjacent to the left sigmoid sinus. Magnetic resonance imaging (MRI) of all the children, performed 2 to 6 days after injury, showed left sigmoid-sinus thrombosis and decreased flow or thrombosis within the lateral third of the left transverse sinus. All the children had MRI scans 4 to 6 weeks after their diagnosis and were followed up for 1 to 12 months. In four children whose symptoms subsided completely within 2 to 10 weeks, MRI showed recanalization of the sigmoid sinus within 4 to 6 weeks after injury. In one child whose symptoms resolved after 6 months, sigmoid-sinus thrombosis persisted with the formation of collateral flow. We conclude that traumatic sigmoid-sinus thrombosis should be suspected when a child has persistent or delayed gait ataxia and vomiting after injury to the back of the head. Computed tomography characteristically demonstrated focal hyperdensity within the sigmoid sinus that we term the dense sigmoid-sinus sign. Because the sinus recanalized and the symptoms subsided in most children within 6 weeks, we conclude that prophylactic medical or surgical intervention is not indicated.

Surgical treatment of aspirin triad sinusitis.

Aspirin sensitivity, asthma, and chronic sinusitis with polyposis comprises the syndrome of Aspirin Triad (AT). The sinusitis associated with this disease is often fulminate and difficult to treat. In order to evaluate the surgical treatment of chronic sinusitis of AT a 17-year retrospective study of 80 patients was performed. Friedman Class III or IV sinus CT scans were present in 73 patients (90%) preoperatively. Twenty-five patients (30.1%) had steroid-dependent asthma and an additional 40 (50%) required intermittent oral steroids for asthma control. All patients underwent bilateral sinus surgery by either a conservative or a radical approach. Patients were followed from 3 weeks to 16 years postoperatively, with an average followup of 3 years. Sixty-eight patients (85%) had significant improvement in their sinus symptoms and 67 (83%) had relief of their asthma. The eight patients (10%) who remained steroid dependent required smaller doses of steroids. Seven patients (8.8%) had nonoperative orbital complications. There was a significant incidence of revision surgery after both conservative and radical sinus procedures. We conclude that surgical treatment by either a conservative or a radical approach controlled the sinusitis in the majority of AT patients, but neither was effective in eliminating the need for subsequent sinus surgery in a significant number of patients with severe sinus disease (Classes III and IV). Control of the sinus disease has a definite beneficial effect on steroid dependency and the need for intermittent oral steroids in managing the asthma in AT. We recommend conservative surgery in the surgical treatment of these patients. AT patients also require close long-term followup with intense medical management of their chronic respiratory inflammation that appears to put them at increased risk for nonoperative complications of their severe sinusitis.

Prevalence of noninvasive fungal sinusitis in South Australia.

BACKGROUND: The aim of this study was to document the prevalence of noninvasive fungal sinusitis in patients with chronic sinusitis and thick viscous secretions in South Australia. METHODS: We studied of 349 patients with chronic rhinosinusitis undergoing endoscopic sinus surgery in a specialized rhinology practice. Patients with nasal polyposis and thick fungal-like sinus mucin had operative samples sent for microscopy and fungal culture. Evidence of atopy was taken as positive radioallergosorbent or skin-prick tests to fungi. RESULTS: One hundred and thirty-four (38%) patients were noted to have thick, viscid sinus mucin, raising suspicion of fungal disease. Ninety-three patients had positive fungal cultures or microscopy (26.6%). It was possible to classify 95.5% of the patients into subgroups of noninvasive fungal sinusitis or nonfungal sinusitis: 8.6% of patients with allergic fungal sinusitis, 1.7% of patients with allergic fungal sinusitis-like sinusitis, 15.2% of patients with chronic fungal sinusitis, one patient with a fungal ball, and the remaining 69% of patients with nonfungal chronic sinusitis. CONCLUSION: This is the first prospective study to evaluate the prevalence of these increasingly widely recognized conditions. It highlights the need for otolaryngologists to be alert to these not uncommon diagnoses in order for early, appropriate medical and surgical management to be instituted.

Para-cavernous sinus venous structures: anatomic variations and pathologic conditions evaluated on fat-suppressed 3D fast gradient-echo MR images.

BACKGROUND: The cavernous sinus communicates with several para-cavernous sinus venous structures, receiving blood flow from the superficial middle cerebral vein (SMCV), the sphenoparietal sinus (SPS), and the superior ophthalmic vein, and draining into the superior and inferior petrosal sinuses and pterygoid and basilar plexuses. Anatomic variations of these veins have been previously reported; however, some details, such as the relationship between the SPS and the SMCV, are incompletely characterized. The anatomic variations of para-cavernous sinus veins, especially drainage patterns of the SMCV, were evaluated on MR imaging. MATERIALS AND METHODS: Thirty-seven patients, including those without any lesions affecting the cavernous sinus or para-cavernous veins and patients with carotid cavernous fistulas, were examined by using fat-suppressed contrast-enhanced 3D fast gradient-echo MR imaging. Two neuroradiologists evaluated the images on a viewer, regarding the normal anatomy and the pathologic findings of the para-cavernous sinus veins. RESULTS: The fat-suppressed 3D fast gradient-echo MR images clearly depicted the para-cavernous sinus venous structures in all patients. SMCVs had 4 variations in the drainage patterns. The most frequent pattern was drainage into the SPS (39%), and other types were draining into cavernous sinus, pterygoid plexus, and tentorial sinus. The SPS had 3 variations. The most frequent pattern was drainage into cavernous sinus (72%), and others were the hypoplastic type or those draining into pterygoid plexus. CONCLUSION: The fat-suppressed 3D fast gradient-echo MR image is useful for evaluating the venous structures in the skull base. Knowledge of the variations is important for diagnosis and endovascular treatment of the cavernous sinus lesions.

Management of acute complicated sinusitis: a 5-year review.

Acute sinusitis is a relatively common problem; however, sinusitis associated with a complication is less frequent. Currently there is debate as to whether acute complicated sinusitis should be managed by frontal sinus trephine and sinus washout or by immediate frontoethmoidectomy/functional endoscopic sinus surgery. To assess the effectiveness of frontal sinus trephine in the management of acute complicated frontal sinusitis, we reviewed all patients admitted to Groote Schuur Hospital with acute pansinusitis (includes frontal, maxillary, and ethmoid) from 1989 to 1993. Eighty-seven patients were admitted, of whom 43 were treated medically and 44 were treated surgically. Of the surgical patients 38 had frontal trephines and management of associated complications. Thirty (80%) of the patients who received frontal trephines recovered without further surgery, and 8 required further sinus surgery for persistent disease. Frontal trephine with management of associated complications is an acceptable management option for patients with acute complicated pansinusitis. Frontoethmoidectomy or functional endoscopic sinus surgery can be held in reserve for those patients with persistent disease that does not resolve after the initial frontal trephine.
