Review the histopathology in 12 cases of reoperation of maxillary sinus

Objectives: Review the maxillary sinus of 12 operated patients by surgical evaluation, Nasal-sinus endoscopy and histopathological tests for finding the fiber tissue whether distributes the maxillary sinus mucosa or not after the radical operation. Results: there is a regeneration of maxillary sinus mucosa following radical operation. This mucosa distributed the infected mucosa that to be removed. The epithelium was regenerated well (8/12 cases) and poor (4/12 cases). The intestinal mucosa was regenerated well (6/12 cases) and poor (6/12 cases)

Histopathological lesions in chronic maxillary sinusitis

94 patients who were 15 years or more were involved in study. These patients were underwent histological examinations. Histopathological revealed variable and complex lesions, with multiple lesions in the same sinus such as mucous degeneration, hyperplasia, dysplasia, atrophy, papiloma, fungus. Lesions in buffer tissues include significant edema, bleeding, congestion, gland proliferation and structural abnormalities.

Microbial in the chronic maxillary sinusitis

A study on the bacterials in the chronic maxillary sinusitis among patients more than 15 years has shown that patients with ages of 15-35 accounted for 78.48%. The antibiogram for microbial isolated from sinus found that sensitivity of microbial to Ciprofloxacin, gentamicin, Cephalexin, erythromycine, chloramphenicols, ampicilline, penicillin, Augmentine, Thiophenicole was 100%, 76%, 63.5%, 15.62%, 17.75%, 8.37%, 6.25%, 5.25% and 2.12%, respectively.
