Canine fossa puncture and clearance of the maxillary sinus for the severely diseased maxillary sinus.

OBJECTIVES: To assess the impact of canine fossa puncture (CFP) with clearance of the maxillary sinus during endoscopic sinus surgery on the subjective and objective outcomes as defined by quality of life questionnaires, endoscopic findings, endoscopic aspirate for culture and sensitivity, and magnetic resonance imaging (MRI) evaluation. STUDY DESIGN: Retrospective, cross-sectional study. METHODS: Twenty-five patients who had undergone canine fossa were compared to 12 patients who had undergone routine endoscopic middle meatal clearance of the maxillary sinus. At an average postoperative time point of 19.9 months, all patients were administered the chronic sinusitis survey (CSS) and a visual analogue scale (VAS). At this visit, patients underwent nasendoscopy, sampling of the ostial region for bacterial and fungal cultures, and MRI of the sinuses. RESULTS: There were 42 sides for analysis from 25 patients on the study arm; the control arm comprised 12 patients with completely opacified maxillary sinuses and 17 sides for analysis. The CSS symptom subscore was better in the CFP group (Mann-Whitney test, P = .02). The overall VAS score was less in the CFP group (Mann-Whitney test, P = .01), indicating better symptom control. No opacification was evident in 61.9% of patients in the CFP group compared with 11.8% in the control arm (chi, P < .001). CONCLUSION: CFP is a useful technique to address the severely diseased maxillary sinus and is associated with significantly better symptom control compared with the transnasal middle meatal antrostomy clearance of the maxillary sinus.

[Surgery of the odontogenic-diseased maxillary sinus. Technic and experiences with the bone cover method].

In the well known extranasal surgical methods described by Caldwell-Luc and Denker, the opening of the bone of the facial wall created during surgery remains open. Scar tissue contract around the infraorbital nerve, fistulae, invasion of soft cheek tissue through the bone defect, and closure of the drainage window may result. The "Bone Lid" method avoids these disadvantages. During osteoplastic surgery of the maxillary sinus routinely performed by the author in more than 700 cases since 1973 a piece of bone (the "Bone Lid") including the attached mucosa is cut out of the anterior wall of the maxillary sinus in such a fashion that it serves perfectly to close the opening again as a free graft at the end of the operation. This procedure simplifies treatment of circumscribed changes in the mucosa, and facilitates precise creation of a drainage window essential for the healing of inflamed mucosa of the maxillary sinus. Coverage of the basal bony lesion initially present at the site of this window by a flap of muco-periosteum is simplified and secured by packing using an inflatable balloon. This stops bleeding reliably in the area of the inferior turbinate and around the window and simultaneously assures ventilation and drainage of the maxillary sinus during the healing period. The techniques used and the experience gained with this method are reported in detail.

[Ultrahigh-frequency radiometry and endoscopy in the diagnosis of maxillary diseases].

The potential of SHF-radiometry was investigated in the diagnosis of maxillary inflammation. Altogether 90 patients and 30 controls underwent routine infrared thermography and SHF-radiometry. Normal thermal distribution in the maxillary sinuses was featured by its picture in normal subjects. SHF-radiometry proved more informative in bilateral localization of the inflammation foci, in sluggish processes in the maxillary sinuses, allowed more significant follow-up of the thermogenic activity of the maxillary deep tissues. SHF-radiometry findings were verified at maxillary endoscopy. The results correlated in 77.9% of the cases. The method can be introduced to make early diagnosis of maxillary inflammation, in mass health check-ups.

[Value of the "Dentascanner"al in dento-maxillary diseases (infectious and cystic)].

MATERIAL AND METHODS: From July 1993 to April 1994, forty dentascans were performed at Bicetre Hospital, on an Elscint Elite Plus scanner for: chronic sinusitis (18 cases); cystic pathologies (8 cases); pre-operative assessment for dental implantation (14 cases). RESULTS: Dentascan images permitted a precise analysis of dentomaxillary anomalies. In all cases they demonstrated the anatomical relationships of the lesions, permitting a determination of potential complications. In chronic sinusitis dental pathology was demonstrated including peri-apical granulomas or cysts breaks or elevations of the floor of the maxillary sinus, malplaced dental filling material in the maxillary antrum and fistula tracks. Among the 14 pre-operative assessments, four cases of infectious lesions were demonstrated, thereby counter-indicating dental implantation. CONCLUSION: The dentascan appears to be very useful for dentomaxillary pathology by facilitating diagnosis and the formulation of treatment and operative strategies.

Penetration of antibiotics into the normal and diseased maxillary sinus mucosa.

A micro-method was developed for determination of the concentrations of antibiotics in the mucous membranes of the maxillary sinus in man. At different times after the administration of antibiotics (potassium phenoxymethylpenicillin, lymecycline and bacampicillin) the concentration was determined in serum and in pieces of maxillary sinus mucosa obtained at operation. It was found that the concentrations in the mucosa varied within wide ranges during the first 60 minutes after the operation but in samples taken at 90 minutes the fluctuations between the individuals were within the standard error of the method. Concentrations well above the MIC values for the majority of bacterias found in sinusitis were registered in the peaks. Six hours after the administration considerable amounts of active antibiotics were still detected in the maxillary sinus mucosa.

The role of the ostiomeatal unit anatomic variations in inflammatory disease of the maxillary sinuses.

OBJECTIVE: The purpose of the study was to determine the correlation between bony anatomic variations of the ostiomeatal unit (OMU) and chronic maxillary sinusitis. The study was based on the hypothesis that the mucosal contact caused by the variations represents the critical factor in increasing the risk of maxillary sinusitis. MATERIALS AND METHODS: Thin section high resolution computerised tomography (CT) examinations of the paranasal sinuses in 73 consecutive patients with 113 anatomic variations of the OMU were retrospectively reviewed. The following CT features were assessed: (1) Type of anatomic variations, (2) presence of a mucosal contact in the OMU and (3) presence of maxillary disease. Statistical evaluation was carried out using chi 2-test. RESULTS: The following bony anatomic variations were found: Concha bullosa (67 cases), abnormalities of the uncinate process (18 cases), Haller's cells (24 cases) and large ethmoidal bulla (four cases). Only 52 of the 113 anatomic variations were associated with ipsilateral maxillary disease (mucosal thickening, mucous retention cysts, polyps, retained secretions). Of 113 variations, 44 caused a mucosal contact, 35 of these were associated with maxillary abnormalities, while in nine cases there were no pathologic changes. Of 69 variations, 17 did not cause mucosal contact (P < 0.05). CONCLUSION: Our data shows that, in the presence of anatomic bony variations, a contact between the mucosal surface of the OMU is valuable in predicting the likelihood of a maxillary inflammatory disease.
