Normalization of maxillary sinus mucosa after FESS. A prospective study of chronic sinusitis with nasal polyps.

To observe the normalization of antral mucosa after FESS, 71 patients suffering from chronic sinusitis with nasal polyps were enrolled in this study. Pre-operative profiles including history, allergy skin test, and saccharin time test were done. Endoscopic findings of the antral mucosa were divided into 3 groups: polyposis, oedema, and thickening. The time sequence required for normalization of the mucosa was observed through the antromeatal opening. A patient's history of more than seven years, a saccharin time longer than 36 min, and polyposis of antral mucosa are ominous signs for recovery. The most frequent endoscopic finding of maxillary sinusitis is oedema and many of the sinus units (42%) gained complete recovery during the third month. Pre-operative profiles and endoscopic findings during surgery can serve as a reference of recovery time and treatment modality.

[The postoperative x-ray morphology of the maxillary sinuses in the conventional x-ray of the paranasal sinuses].

This paper presents the postoperative x-ray morphology and clinical findings of surgically cleared maxillary sinuses. 64 patients who had undergone osteoplastic surgery as well as 48 patients subjected to conventional classical Caldwell-Luc surgery could be followed up. Those patients on whom osteoplastic maxillary surgery had been performed, had significantly fewer postoperative complaints than patients subjected to osteoplastic surgery (p < 0.05). X-ray morphology also differed significantly between the two groups. For example, patients with osteoplastic trepanation showed a significantly higher rate of maxillary sinuses with complete pneumatisation (p < 0.01) during follow-up. By contrast, osteoclastic operations showed more postoperative total opacity (p < 0.01) and marginal opacities (p < 0.05) in the maxillary sinuses.

[Endoscopic sinus surgery for the treatment of inverted papilloma of nasal cavity and paranasal sinuses].

Fourteen patients suffering from inverted papilloma of the nasal cavity and sinus were operated by the intranasal endoscopic approach. The period of follow-up were 24-60 months. Only one case had recurrence after three months and was then cured by a combined treatment of external nasal approach and radiotherapy. The other 13 cases had no recurrence in the follow up period. The intranasal endoscopic surgical technique was proved a better method for treating inverted papilloma of nasal cavity and sinus even when the lesions had affected the posterior ethmoid and spenoidal sinuses. It seems that this approrch would be a new way for removing inverted papilloma completely and the major advantage of which is an incision of the face can be avoided, while the curative rate might be the same or even better than that of the external approach.

[Roentgenologic, endoscopic and ultrasound evaluation of the maxillary sinus after sinus lift with simultaneous endosseous implantation].

X-ray, ultrasound, and endoscopy were used in follow-up after sinus floor augmentation. In 23 out of 63 patients, healing was uneventful. Water's view revealed opacification of the maxillary sinus 1 week postoperatively in 40 patients, and opacification persisted in four patients. In these patients, endoscopy showed inflammatory reactions of the mucosa. Ultrasound proved to be a valuable tool in follow-up. Sinusitis occurred in three patients and was due to migration of bone chips in two of these. Out of 132 inserted implants, eight were lost during the healing period and three more during the loading period.

Role of sinus node artery disease in sick sinus syndrome in inferior wall acute myocardial infarction.

This study was undertaken to evaluate a possible role of sinus node (SN) artery disease in the pathogenesis of sick sinus syndrome (SSS) in patients with an inferior wall acute myocardial infarction (AMI). Coronary angiography and electrophysiologic studies of the SN, both in the basal state and after pharmacologic autonomic blockade, were performed in 23 study patients (mean age 60 years) with SSS and a previous inferior wall AMI and in another 23 control patients (mean age 57 years) with normal sinus rate and a previous inferior AMI. Stenosis of the SN artery (or that proximal to its origin) greater than 50% was present in 13 study patients (56%) and in 8 control patients (34%) (p less than 0.05). In the study group, the intrinsic heart rate was abnormal in 5 of the 6 patients (83%) with severe SN artery stenosis (greater than or equal to 75% narrowing), in 3 of the 7 (43%) with moderate stenosis (50 to 75% narrowing) and in 3 of the 10 (30%) with insignificant stenosis (less than 50% narrowing). In the study group, the correlation between the SN measures (heart rate, corrected SN recovery time and sinoatrial conduction time) and the severity of SN artery stenosis was good after autonomic blockade (r between 0.59 and 0.64) and poor in the basal state. These data provide evidence for a role of SN artery disease in the pathogenesis of SSS in patients with an inferior wall AMI.

Comparison of moxifloxacin and cefuroxime axetil in the treatment of acute maxillary sinusitis. Sinusitis Infection Study Group.

The aim of this prospective, multicenter, randomized, double-masked clinical trial was to compare the efficacy and safety of moxifloxacin with those of cefuroxime axetil for the treatment of community-acquired acute sinusitis. Five hundred forty-two adult patients with symptoms and radiographic evidence of acute maxillary sinusitis received a 10-day oral regimen of either moxifloxacin (400 mg once daily) or cefuroxime axetil (250 mg twice daily). Acute signs and symptoms at presentation had lasted >7 days but <4 weeks. Clinical response at the end of therapy (7 to 14 days after treatment) was the primary efficacy variable. Four hundred fifty-seven of the patients (223 moxifloxacin, 234 cefuroxime axetil) were included in the clinical efficacy analysis. Moxifloxacin was found to be similar in effectiveness to cefuroxime axetil at the end-of-therapy visit (90% vs. 89%, respectively; 95% confidence interval, -5.1% to 6.2%). Clinical relapse at the follow-up visit was reported for only 8 patients (3 moxifloxacin, 5 cefuroxime axetil). No clinically significant differences were observed with respect to the number of patients experiencing a successful clinical response based on demographic or infection characteristics. Five of the 542 enrolled patients were lost to follow-up. Of the 537 patients in the intent-to-treat population, drug-related adverse events were reported in 37% of moxifloxacin-treated patients and in 26% of cefuroxime axetil-treated patients (P = 0.006). Adverse-event profiles were comparable in the 2 treatment groups, with the exception of nausea, which was reported by 11% of moxifloxacin-treated patients compared with 4% of cef uroxime axetil-treated patients (P = 0.003). In this study, moxifloxacin was as effective as cefuroxime axetil in the treatment of community-acquired acute sinusitis.

Endoscopic trans-nasal-vestibular approach to the maxillary sinus--application for mucoceles of the maxillary sinus.

Endoscopic endonasal surgery has been applied to the treatment of paranasal mucoceles. The approach is, however, hard to be adopted for maxillary mucoceles when the cyst is situated in the anterior and/or lateral portion of the maxillary sinus, has a thick bony lateral wall of the inferior nasal meatus, and when the patients develop compartmentalized cysts following facial trauma or sinus operation. We devised an endoscopic approach via the vestibule of the nose to reach any part of the maxillary sinus and applied it for the treatment of postoperative maxillary mucoceles, which could not be opened following the usual endoscopic approach with favorable outcomes.

Blood supply to the maxillary sinus relevant to sinus floor elevation procedures.

The maxillary blood supply is essential for preserving the vitality of the affected maxillary region, integration of the grafting material, and wound healing such as following sinus floor elevation. Although it is well established that edentulous maxillae demonstrate a decreasing vascularity as bone resorption progresses, the vascular conditions relevant to sinus floor elevation procedures have not been investigated yet. This study deals with maxillary arteries relevant to sinus floor elevation surgery and examines the vascularization of the lateral maxilla after tooth loss. The vessels of the lateral maxilla of 18 maxillary specimens (10 male, 8 female, mean age 67 years) were prepared anatomically and the local main arteries, the number of macroscopically discernible branches and anastomoses, their calibers, and the distance between the caudal main branches and the alveolar ridge recorded. The lateral maxilla is supplied by branches of the posterior superior alveolar artery (PSAA) and the infraorbital artery (IOA) that form an anastomosis in the bony lateral antral wall, which also supplies the Schneiderian membrane. This intraosseous anastomosis was found in all of the specimens. Eight of 18 also showed an extraosseous anastomosis between PSAA and IOA, vestibular to the antral wall, giving off an average of 3 branches cranially and 5 branches caudally. The two anastomoses form a double arterial arcade to supply the lateral antral wall and, partly, the alveolar process. The PSAA had a mean caliber of 1.6 mm and exhibited an average of 2 endosseous and 1 extraosseous branches. The IOA had a mean diameter of 1.6 mm and showed an average of 1 endosseous and 3 extraosseous branches. The mean distance between the intraosseous anastomosis and the alveolar ridge was 19 mm in 2 defined measuring sites. Its mean length was 44.6 mm. The epiperiosteal vestibular anastomosis was situated further cranially at a mean distance of 23 to 26 mm from the alveolar ridge and had a mean length of 46 mm. The rather large caliber of the vessels supplying the lateral antral wall seems to be crucial to the fact that the periosteal blood supply is maintained even in severe maxillary atrophy and after complete disappearance of the centro-medullary vessels.

Assessment of maxillary sinus volume for the sinus lift operation by three-dimensional magnetic resonance imaging.

OBJECTIVES: To calculate sinus and bone graft volumes and vertical bone heights from sequential magnetic resonance imaging (MRI) examinations in patients undergoing a sinus lift operation. METHODS: MRI scans were obtained pre-operatively and at 10 days and 10 weeks post-operatively, using a 0.95 tesla MRI scanner and a three-dimensional (3D) magnetisation prepared, rapid acquisition gradient-echo (MP-RAGE) sequence. RESULTS: Estimates of the bone graft volumes required for a desired vertical bone height were made from the pre-operative MRI scan. Measurements of the graft volumes and bone heights actually achieved were made from the post-operative scans. The MRI appearance of the graft changed between the 10 day and 10 week scans. CONCLUSIONS: We have proposed a technique which has the potential to give the surgeon an estimate of the optimum volume of graft for the sinus lift operation from the pre-operative MRI scan alone and demonstrated its application in a single patient. Changes in the sequential MRI appearance of the graft are consistent with replacement of fluid by a matrix of trabecular bone.

Functional endoscopic sinus surgery in chronic sinusitis--a series of 237 consecutively operated patients.

From 1989 to 1999, 237 consecutive patients with chronic sinusitis and/or nasal polyposis entered a prospective study on the effect of functional endoscopic sinus surgery (FES). Nasal stenosis associated with massive nasal polyposis was the most frequent problem found in 61% of the patients. The rest had long-lasting symptoms of chronic sinusitis. Duration of symptoms averaged 9.3 years. Most frequent symptoms preoperatively were: nasal stenosis, chronic secretion, anosmia, frontal pain, headache and maxillary pain. All patients had the operation performed under general anaesthesia. 86% of the patients have been operated bilaterally. In 72% the posterior ethmoid was opened, and in 54% the sphenoid was opened. The maxillary ostium has been enlarged in 82% of the patients and the frontal recess opened in 51% of the cases. No serious complications were registered. Annoying bleeding was experienced in 21%, hampering the intended procedure. In three patients rhinoliquore was observed. One case was treated during the procedure; the last two patients were in no need of surgical treatment. At the 1-year follow-up study, 45% of the patients were totally satisfied with the results and without symptoms, and 44% were definitely feeling better.

Antimicrobial resistance in the nasopharyngeal flora of children with acute maxillary sinusitis and maxillary sinusitis recurring after amoxicillin therapy.

OBJECTIVE: To investigate the antimicrobial susceptibility of the organisms isolated from the nasopharynx of children who present with acute maxillary sinusitis (AMS) or maxillary sinusitis that recurred (RMS) after amoxicillin therapy. METHODS: Analysis of nasopharyngeal cultures obtained from 70 patients, 42 with AMS and 28 with RMS. RESULTS: Thirty-eight potentially pathogenic organisms were recovered in 36 (86%) of the children from the AMS group, and 40 were isolated from 26 (93%) of the children from the RMS group. The organisms isolated were Streptococcus pneumoniae (21 isolates), Haemophilus influenzae non-type b (17), Moraxella catarrhalis (15), Streptococcus pyogenes (13) and Staphylococcus aureus (12). Resistance to the eight antimicrobial agents used was found in 34 instances in the AMS group compared to 93 instances in the RMS group (P < 0.005). The difference between AMS and RMS was significant with S. pneumoniae resistance to amoxicillin (P < 0.0025), to co-amoxiclav (P < 0.0025), to trimethoprim-sulfamethoxazole (P < 0.05), to cefixime (P < 0.05), and to azithromycin (P < 0.05), and for H. influenzae to amoxicillin (P < 0.025). CONCLUSIONS: These data illustrate the higher recovery rate of antimicrobial-resistant S. pneumoniae and H. influenzae from the nasopharynx of children who had maxillary sinusitis that recurred after amoxicillin therapy than those with AMS.

Normal sinus heart rate: appropriate rate thresholds for sinus tachycardia and bradycardia.

Conventional rate limits for sinus rhythm--100/min as the tachycardia threshold and 60/min as the bradycardia threshold--were established by consensus and never formally examined. Because clinical experience indicated that both figures were too high, we investigated this formally in 500 normal individuals. Results were consistent with normal data from the Framingham Study 5,000-subject cohort and the EPICORE Center cohort of more than 18,000 normal persons. Therefore, rounded tachycardia and bradycardia thresholds of 90/min and 50/min for normal sinus rhythm should improve the sensitivity of tachycardia detection and the specificity of bradycardia detection. The appropriate rate range (rounded) for sinus rhythm is 50/min to 90/min.

Reappearance of persistent normal sinus rhythm in a patient with the sick sinus syndrome following cardiac pacing for 10.5 years.

A patient with symptomatic sick sinus syndrome which manifested as a brady-tachy syndrome, was admitted to our institute in 1969. Following cardiac pacing for 10.5 years, the brady-tachy syndrome disappeared and normal sinus rhythm was restored. Her stable normal sinus rate has persisted up to the present, 2.5 years after termination of pacing.

Recovery of sinus node function after pacemaker implant for sinus node disease following cardiac transplantation.

In a 4-year interval, 3/55 (7.8%) heart transplant recipients developed (greater than 4 weeks) severe sinus node dysfunction. An epicardial ventricular pacemaker was implanted at 90, 40, and 38 days after operation. Follow-up ranged from 7 to 20 months. In two of the three cases, failure of stimulation or sensing was detected at the 3rd and 4th month after pacemaker implantation. Sinus rhythm reappeared in two of the three patients at the 2nd and 4th months after transplantation. Severe sinus node disease requiring pacemaker implantation can improve following the first 3 months after transplantation. Failure of stimulation or sensing may not be uncommon.
