Osteoplastic surgery of the sinus maxillaris--the "bone lid"-method.

During osteoplastic surgery of the maxillary sinus the surgical defect in the lateral wall of the maxillary sinus is re-closed by means of free reimplantation of the "bone lid", which had been temporarily removed together with the integral mucosa, during creation of the access. This "bone lid"-method has so far been employed successfully in approx. 600 cases. For covering the basal area of the bone lesion of the drainage window to the lower nasal passage, created during surgery by means of a flap of mucosa and periosteum, a novel type of tamponade using an inflatable balloon was tested. The following pages report on the surgical techniques employed and on systematic follow-up investigations.

Histologic changes in the sinus membrane after maxillary sinus augmentation in goats.

PURPOSE: Previous studies have reported on the morphologic aspects of bone regeneration after maxillary sinus grafting. However, no previous studies have examinated the morphology of the maxillary sinus mucosa after grafting. The purpose of this study was to evaluate the histologic changes in the lining membrane after sinus augmentation. MATERIALS AND METHODS: A unilateral osteotomy of the lateral maxillary wall, medial displacement of the bony segments, and elevation of the sinus mucosa were performed in 12 goats. An autogenous bone graft combined with coralline particles was placed on the floor of the sinus in three animals, and coralline particles alone were placed in three other goats. Six goats were not grafted and were used as controls. Samples were harvested at 2.5, 4.5, and 6.5 months. The maxillary sinus mucosa was examined using light microscopy and scanning and transmission electronic microscopy. RESULTS: The coralline particles were surrounded by fibrous connective tissue when used alone. The addition of iliac crest bone to the coralline particles stimulated bone formation. After the sinus augmentation, the mucosal lining showed a lack of glands in the lamina propria, and the epithelium showed an increase in goblet cells. CONCLUSION: It was concluded that the sinus mucosa undergoes physiologic adaptations and remains healthy and free of chronic sinusitis after maxillary sinus grafting.

[Maxillary sinus hypoplasia].

Maxillary sinus hypoplasia is rare, with an estimated prevalence of 1-5%. Out of the CT scans performed in sinusal patients between March 1998 and June 1999, we report on 4 isolated maxillary sinus hypoplasia, 4 maxillary sinus hypoplasia associated to concha bullosa, and 10 isolated conchae bullosas. All cases were evaluated by nasosinusal endoscopy and CT scan. Size, location and uni/bilateral presentation of concha bullosa is correlated to maxillary sinus hypoplasia presence, specially with regards to uncinate process presence, medial or lateral retraction. The pathogenesis of maxillary sinus hypoplasia is reviewed, and its relation to concha bullosa, evaluating how this could explain some cases of the so called chronic maxillary sinus atelectasia, as an acquired and progressive variant of maxillary sinus hypoplasia in adults.

[Comparative microbiological, macro- and microscopic and x-ray findings in iatrogenic perforation of the maxillary sinus depending on the time of its lancing].

To determine whether the inflammation afflicting the sinus mucosa shortly after oroantral communication is due to an injury or an infection, microbiological studies of two biopsy preparations each were performed simultaneously in 20 patients with the diagnosis: radix in antro. As a rule, notwithstanding the time of oroantral communication aerobe micro-organisms corresponding to the local conditions of oral and nasal flora. Primary asepsis of the sinus mucosa being assumed, an infection of the sinus maxillary has to be taken into account only one hour after the dislocation of a root of the tooth into the sinus maxillary. After six hours the infection will be followed by an inflammatory reaction.

Measurement of velocity of air flow in the sinus maxillaris.

Anemometry with the hot wire and hot film technique previously described, enables the rhinologist to record slow and rapidly changing air flow in the maxillary sinus. The advantages and disadvantages of this method are considered. Anemometry together with manometry may be designated sinumetry and used as a diagnostic procedure following sinuscopy in chronic maxillary sinus disease. The value of the function from velocity of time allows the estimation of flow-volume in the sinus. Furthermore, the method is useful to evaluate the optimal therapy to restore ventilation in the case of an obstructed ostium demonstrated before and after surgical opening in the inferior meatus.

[A case of recurrent untreated non-hodgkin's lymphoma localized in the nasopharynx and maxillary sinuses after a 10-year remission].

We present the case of non-Hodgkin lymphoma (lymphoma malignum lymphocyticum) localised in nasal cavity and paranasal sinus (maxillary sinus). The patient suffered from weakness, fever and rhinorrhoea. We applied the chemotherapy (grade IV degrees) in COP, achieving partial remission. We also place emphasis on 10-year period of idiopathic neoplasm remission since the establishment of diagnosis.

[Mucocele of maxillary sinus].

The term mucocele designates a cyst developing from a sinus mucosa, generally the frontal and/or ethmoidal sinuses. Maxillary sinus localization is exceptional however and raises numerous diagnostic problems in daily practice. The antral mucoceles are potentially destructive lesions, often secondary to Caldwell-Luc procedure. In this article are described in some detail the clinical, radiological and histopathological features of true antral mucoceles.

[The value of maxillary sinus irrigation in children with maxillary sinusitis using the Waters film].

Eighty children with chronic sinusitis receiving a conservative treatment were followed. They found that without any further therapy the Waters view of 30 children became normal. The usefulness of irrigation of the maxillary sinus was studied in the other 50 children. In one group of 25 children a sinus endoscopy and sinus irrigation was performed. In a control group of another 25 children no further treatment was performed. A comparison between the Waters view and sinus endoscopy is also included in the study. The authors found little difference in the treatment results in the two groups. Furthermore, when the Waters view is normal, then exists little chance of finding a pathological mucous membrane during sinus endoscopy. In doubt the clinical picture is most important. The control of the roentgenogram should be performed one month after the first one. Antroscopy is better for the diagnosis but in view of its traumatic aspect and the finding that it does not result in a better therapeutic response, the authors advise sinus irrigation only in problematic cases.

Penetration of erythromycin stearate into maxillary sinus mucosa and secretion in chronic maxillary sinusitis.

The penetration of oral erythromycin stearate (Abboticin), administered in a dosage of 500 mg three times a day, into the maxillary sinus mucosa and secretion was studied in 15 patients (22 sinuses) operated on for chronic maxillary sinusitis. The average concentration in serum was 2.3 microgram/ml, 1.2 microgram/ml in secretion, and 1.8 microgram/ml in mucosa. These concentrations are highly effective against diplococci and most aerobic and anaerobic streptococci (MIC value 0.06 microgram/ml) but not against Haemophilus influenzae (MIC value for 80% of 2 microgram/ml).

Carcinoma of maxillary sinus, palate and maxillary gingiva: occurrence of jaw destruction.

A comparison was made between the frequency of alveolar bone-palate destruction caused by carcinomas originating in the maxillary sinus (31 patients), palate (15) and maxillary gingiva (9). Radiographic examination included conventional sinus projections, supplemented with hypocycloid tomography (47), computed tomography (28) and orthopantomography (11). Almost every second tumor presenting with alveolar bone involvement appeared to be a maxillary sinus cancer. Gingival and palatal cancers also caused frequent bone destruction. Radiographic examination, including tomography, was of great value in demonstrating the extent of these tumors. Three cases clinically diagnosed as gingival cancers proved to originate in the maxillary sinus.

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.

Molecular analysis of bacterial flora associated with chronically inflamed maxillary sinuses.

Chronic maxillary sinusitis is a chronic inflammatory condition in which the role of microbial infection remains undefined. Bacteria have been isolated from chronically inflamed sinuses; however, their role in the chronicity of inflammation is unknown. The objective of this study was to determine whether bacteria are present in clinical samples from chronic maxillary sinusitis and to assess the diversity of the flora present. Washes and/or tissue samples from endoscopic sinus surgery on 11 patients with chronic maxillary sinusitis were subjected to PCR amplification of bacterial 16S rDNA using three universal primer pairs, followed by cloning and sequencing. The samples were also assessed for the presence of bacteria and fungi by conventional culture methods. Viable bacteria and/or bacterial 16S rDNA were detected from maxillary sinus samples of five of the 11 patients examined (45 %). Three sinus samples were positive by both PCR and culture methods, one was positive only by PCR, and one only by culture. Thirteen bacterial species were identified: Abiotrophia defectiva, Enterococcus avium, Eubacterium sp., Granulicatella elegans, Neisseria sp., Prevotella sp., Pseudomonas aeruginosa, Serratia marcescens, Staphylococcus aureus, Stenotrophomonas maltophilia, Streptococcus gordonii, Streptococcus mitis/Streptococcus oralis and Streptococcus sp. Fungi were not detected. In one patient Streptococcus mitis/Streptococcus oralis, and in another patient Pseudomonas aeruginosa, were detected from both the sinus and the oral cavity using species-specific PCR primers. These results suggest that both aerobic and anaerobic bacteria can be detected in nearly half of chronic maxillary sinusitis cases.

A cadaveric study of maxillary sinus size as an aid in bone grafting of the maxillary sinus floor.

PURPOSE: This study measured maxillary sinus volume as an aid in determining graft bone volume before grafting of the maxillary sinus floor. MATERIALS AND METHODS: Maxillary sinus size was measured in 32 cadavers (59 sinuses) using casts of the maxillary sinus made using dental impression material. RESULTS: Anteroposterior length, height, width, and volume of the maxillary sinus (mean+/-SD) were 30.1+/-5.65 mm, 34.6+/-7.71 mm, 25.4+/-5.71 mm, and 11.3+/-4.60 cm3, respectively. When the sinus-lift procedure was simulated, inferior sinus volumes (mean +/- SD) were 3.51+/-1.23 cm3 for a 15-mm lift and 5.66+/-1.71 cm3 for a 20-mm lift. CONCLUSIONS: In bone grafting of the maxillary sinus floor, taking into consideration individual differences in maxillary sinus volume and resorption of the grafted bone, 4.74 cm3 or more of the graft is required for a 15-mm lift, and 7.37 cm3 or more is required for a 20-mm lift.
