[MRI in the preoperative diagnosis of chronic sinusitis: comparison with CT].

PURPOSE: To determine the value of MRI in the preoperative evaluation of chronic paranasal sinusitis and to compare the results with CT and intraoperative findings. METHOD/MATERIALS: 42 patients with clinical signs of chronic paranasal sinusitis underwent MRI after CT evaluation on one day, with subsequent functional endoscopic sinus surgery on the next day. Coronary CT was obtained with 5-mm slices and table-feed in the prone position, while MRI was performed in the supine position with coronary T2-TSE + pd and coronary and transverse HASTE, each with 5-mm slice thickness. Aquisition time in MRI was less than 8 minutes. Two radiologists reviewed the CT and MRI scans for signs of sinusitis and detection of anatomical landmarks. The results were correlated with the intraoperative findings. RESULTS: MRI offered no artifacts of dental work and showed more often high quality pictures than CT. CT and MRI demonstrated a good correlation in the detection of mucosal pathologies (kappa = 0.46-0.87) and anatomic variants (kappa = 0.55-0.86). All important anatomical structures could be evaluated sufficiently with MRI for preoperative management. Both diagnostic tools showed an unsatisfactory correlation with intraoperative findings in the ethmoidal complex and maxillary sinus (tau = -0.08-0.3). CONCLUSIONS: MRI is a fast and reliable alternative to preoperative CT in examining paranasal sinuses and offers a good visualization of mucosal changes. CT and MRI both give an unreliable representation of the ethmoidal complex.

Chronic sinusitis in patients with cystic fibrosis.

Cystic fibrosis is a lethal genetic disorder whose victims currently have a median life span of approximately 30 years. With this increased life span, new aspects of the disease are identified in patients with cystic fibrosis, including chronic sinusitis. Sinusitis severely affects the quality of life of patients with sinusitis. This article discusses several aspects of sinusitis in patients with cystic fibrosis, including clinical presentation, radiologic findings, and treatment options. By recognizing and treating sinusitis in patients with cystic fibrosis, physicians may improve the quality of life of these patients.

Management of chronic sinusitis in the adult cystic fibrosis patient.

Cystic fibrosis (CF) is an autosomal recessive disorder affecting exocrine gland function. Although CF was formerly a deadly disease of infants and children, recent improvements in antibiotics, nutritional therapy, and supportive care have extended the median survival to adulthood. Patients with CF often present with sinusitis and nasal polyposis in addition to recurrent pulmonary infections. Although the effectiveness of endoscopic sinus surgery in children with CF has been documented, the treatment guidelines and efficacy in the adult CF patient are unknown. We present a series of 16 adult patients with CF and chronic sinusitis. The majority of patients presented with nasal polyposis and concomitant pulmonary complications. Endoscopic findings are reviewed, with an emphasis on improving pulmonary function following endoscopic sinus surgery. Preliminary findings suggest that endoscopic sinus surgery improves symptoms of sinusitis and exercise tolerance and may delay the progressive respiratory failure that often affects the adult CF patient.

[Bipolaris australiensis in a Spanish patient with allergic chronic sinusitis].

Allergic fungal sinusitis is a disease that results from hypersensitivity reaction of the host against fungi colonizing the paranasal sinuses. A 36 years old Spanish man with no history of travel abroad had a history of asthma, nasal polyps, allergic rhinitis and a chronic sinusitis with nasal congestion and headaches. Computed tomography showed pansinusitis and opacification of the paranasal sinuses. A pure culture of Bipolaris australiensis was grown from sinus tissues. Infections caused by Bipolaris spp. and treatment regimes are discussed.

Microbiology of acute and chronic sinusitis in children and adults.

The microbiology of infections of the paranasal sinuses can be anticipated according to the patient's age, clinical presentation, and immunocompetence. In acute sinus disease, viral upper respiratory infections frequently precede bacterial superinfection by Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. Staphylococci and respiratory anaerobes are common in chronic sinus infection, which may also be caused by exacerbations of infection with the bacterial species that cause acute disease. Enterobacteriaceae may be found in patients with nosocomial sinusitis who are predisposed to the development of sinusitis by prolonged nasogastric and nasotracheal intubation. Immunosuppressed patients have episodes of sinusitis caused by the usual agents associated with acute sinusitis in immunocompetent patients, and they may also become infected with a broad array of unusual agents, including mycobacterial species, fungi, and protozoa.

Bacterial patterns found in surgery patients with chronic sinusitis.

Aseptic samples of sinus mucosa or aspirates from maxillary sinuses were taken from 197 patients who underwent sinus surgery and were cultured for aerobic bacteria. Anaerobic cultures were also obtained from 143 of these patients. A total of 236 bacterial isolates from 174 patients were analyzed. No anaerobic organisms were isolated. The most commonly isolated organisms were Staphylococcus species (coagulase-negative), Staphylococcus aureus, gram-negative bacilli, and Streptococcus species. Penicillin G, erythromycin, tetracycline hydrochloride and, to a lesser degree, first-generation cephalosporins were found to be inferior to ciprofloxin, trimethoprim/sulfamethoxazole, and cefuroxime axetil when the susceptibilities of all the bacterial isolates to oral antibiotics used commonly in the empiric therapy of chronic sinusitis were compared.

Surfactant and its role in chronic sinusitis.

Although numerous studies have focused on the nature and defensive role of surfactant in the lower airways, relatively little is known about its role in the upper airways. Decreased levels of the main component of surfactant--phospholipids--have been implicated in atrophic rhinitis. The lamellar body arrangement of phospholipids has now been demonstrated in both normal and diseased sinus tissue, resulting in the implication that these structures may play a crucial role in mucociliary clearance against inhaled pathogens, as well as in the regulation of mucous viscosity. Furthermore, they may be secreted from sinonasal ciliated epithelium. Surfactant proteins (SPs) make up a relatively smaller proportion of surfactant, but appear to have an important role in innate immunity. Altered levels of SPs have been observed in a number of respiratory tract diseases. These SPs may prove to play a significant role in chronic sinusitis. Demonstrated expression of SP-A and SP-D in diseased and normal sinus tissue may mean that these SPs are excreted into the airway-lining fluid of the sinuses. Additionally, initial contact and interaction between pathogens and SP-A and SP-D may occur relatively early after inhalation and deposition into the mucus of the respiratory tract. These findings may lead to potential therapeutic options for difficult-to-treat sinus disease in the future.

Perennial allergic rhinitis and chronic sinusitis: correlation with rhinologic risk factors.

BACKGROUND: The reported association of allergy and sinusitis varies greatly between study, and the exact role of allergy in predisposing to sinusitis is not clear. We attempted to determine whether patients with perennial allergic rhinitis are at greater risk of developing sinusitis with respect to a control group, and to determine whether there is a correlation between rhinomanometry, endoscopy, and nasal swab, and computed tomography (CT) findings. METHODS: Forty adult patients with perennial allergic rhinitis underwent CT scans of the paranasal sinuses, and the results were then compared to CTs of the paranasal sinuses of 30 control subjects. All allergic patients underwent nasal endoscopy, nasal swab, and active anterior rhinomanometry, and the results were studied in relation to the CT findings. RESULTS: We found sinusitis in 67.5% of the allergic patients and in 33.4% of the controls, with a statistically significant difference between the two groups (P = 0.017). Twenty-three patients had a positive nasal swab; 22 showed increased nasal resistance on rhinomanometry, and 36 had positive endoscopy, but the association of CT findings with endoscopy, rhinomanometry, or nasal swab was not statistically significant (P = 0.583, P = 1.00, P = 0.506, respectively). CONCLUSIONS: Allergic rhinitis is often associated with sinusitis, but the underlying mechanism has yet to be determined. Evidently, factors other than classical pathogen growth and mechanical factors, such as the association of the various factors and immunologic mechanisms, may contribute to the pathogenesis of chronic sinusitis in allergic patients.

Chronic sinusitis: relationship between CT findings and clinical history of asthma, allergy, eosinophilia, and infection.

An interdisciplinary study from the University of Virginia was reported in a recent issue of the Journal of the American Medical Association (JAMA) [1]. The results of that study are pertinent to radiologists who interpret CT scans for patients with chronic sinus disease. The study examined the relationship among eosinophilia, asthma, allergy, and sinusitis and assessed the findings obtained for the paranasal sinuses by high-resolution CT. Soft-tissue disease seen within the paranasal sinuses on CT scans is often described as mucosal thickening or mucoperiosteal thickening, with little attention to its exact nature. The JAMA article showed that for patients properly prepared for sinus CT, the thickened mucosa depicted within the sinonasal cavity is a significant site of functional, immunologically active tissue. The purpose of this article is to bring the findings of the JAMA report to the attention of radiologists and to emphasize the imaging technique, findings, and clinical relevance of the results.

Chronic sinusitis: a sequela of inferior turbinectomy.

Inferior turbinectomy has generated a great deal of controversy among rhinologic surgeons. Proponents of partial and total inferior turbinectomy cite numerous studies of large numbers of patients with subjective relief of nasal obstruction after turbinectomy. Clinical studies critical of turbinectomy have focused on complications such as hemorrhage, crusting, adhesions, and atrophic rhinitis. Our study was undertaken to evaluate the incidence of chronic sinusitis post inferior turbinectomy. Postoperative evaluation by history, physical examination, and computerized tomography of the paranasal sinuses revealed that a significant number of patients who underwent inferior turbinectomy developed sinusitis. Patients evaluated in our clinic for nasal obstruction underwent a detailed history, physical examination along with nasal endoscopy and coronal computerized tomography of the paranasal sinuses. Those patients with nasal obstruction not responsive to medical treatment and without evidence of sinusitis underwent submucous resection and inferior turbinectomy. The incidence, cause, and possible prevention of post inferior turbinectomy sinusitis is discussed in this article.

Concha bullosa in chronic sinusitis.

Sinusitis is an important cause of morbidity and one of the major sources of income loss. Anatomical variations of the nose have been reported to predispose to sinusitis. These variations include concha bullosa, nasal septal deviation and oversized bulla. The aim of this study was to determine the proportion and the distribution of concha bullosa in patients with chronic sinusitis and to determine the relationship between concha bullosa and age, sex, ethnicity. A cross-sectional study was conducted at the Department of Ear, Nose and Throat in Kuala Lumpur Hospital (HKL). Data was collected retrospectively using a pretested proforma. All patients who underwent Sino nasal surgery between January 1999 and December 2000 and whose preoperative CT scans were available were included in the study. The CT scans were reviewed. Analysis was carried out using Statistical Package for Social Sciences. Out of 146 patients who underwent sinonasal surgery between January 1999 and December 2000, 101 (69.2% preoperative CT scans of these patients were available and these were reviewed. The proportion of patients with concha bullosa was 49.5%. The results showed that there was significant relationship between presence of concha bullosa and age and sex. The overall mean age of patient with concha bullosa was 35.7 years (95% CI 12.1-39.3) and ranged from 11-years to 56-years. The mean age of respondents with concha bullosa was significantly lower than patients without concha bullosa 41.98 (95% CI 37.6-46.3; t-test = 2.221; df=99; p < 0.05). Concha bullosa was significantly more in females (66.0%) compared to males (chi2 = 4.465, df=1, p < 0.05). There was no significant relationship between presence of concha bullosa and ethnicity.

Postoperative olfaction in chronic sinusitis: smokers versus nonsmokers.

In order to study the efficacy of surgical intervention, as well as the influence of cigarette smoking on olfaction in clinical states, we examined olfactory ability by means of the University of Pennsylvania Smell Identification Test (UPSIT). We enrolled 37 patients 21 to 60 years of age who underwent surgery for chronic sinusitis. Normosmia was defined as an UPSIT score of 30 or more. Among these patients, 31 had a disturbance in their smelling ability in the preoperative stage, and the improvement rate, defined as a rise in score of 4 or more points after surgery, was 64.5%; 11 were well healed. However, all 7 patients who were more than 40 years old at the time of surgery, and currently smoking cigarettes, had a significant deficit in olfaction in the preoperative stage and even in the postoperative stage. This study demonstrated that cigarette smoking has adverse effects on olfactory ability, especially for older patients.
