Abstract
Objective: The object of the study was to determine the effect of the middle ear (ME) inflation and to clear up the factors affecting the results of conservative treatment of secretory otitis media (SOM) in adults. Methods: A total of 146 adult patients were treated by middle ear inflation (group A) or by inflation and antibiotics (group B) for 10±2 days. Pneumootoscopy, pure tone audiometry and impedansometry were carried out on the 3rd–5th, 10th and 60th day of the study. To determine the relative importance of analyzed findings as a prognostic contributive factor, stepwise logistic regression was carried out and positive/negative prognostic value of these factors was assessed. Results: The effectiveness of treatment was 50.6% in group A and 58.7% in group B (control group—11%, p<0.001). The results of treatment were stable and were found unchanged 6 weeks after the treatment. The most important prognostic criteria were defined by analyzing the dynamics of tympanometry (OR-2.17) and pure tone audiometry (OR-10.27) during conservative treatment and after it. The results of the treatment were related to the mastoid pneumatization, the pathology of paranasal sinuses, the previous history of SOM, the age and the pre-treatment otoscopic data.
