Abstract

The purpose of this survey is determining of the prevalence of different lesions of MIDDLE EAR, with special respect to CHRONIC OTITIS MEDIA (COM) in our society, and also searching about predicting of MIDDLE EAR lesions before surgery with the use of PREOPERATIVE AUDIOMETRY. In this study, which is consisted of 50 cases, 88% of surgical procedures on MIDDLE EAR has been done because of COM. The prevalence of chronic perforations with and without CHOLESTEATOMA was 18% ant 52%, respectively. In the cases of COM without CHOLESTEATOMA, granulation tissue, tympanosc1erosis, chronic perforation without any of them was 16%, 14%, 26%, retraction. The prevalence 'of retraction pocket with CHOLESTEATOMA was 10% and without CHOLESTEATOMA was 8% . CHOLESTEATOMA existes in almost half of the eases of COM. Ossicular erosions were found at 40% of all patients and 45% of COM. As a result when there is air - bon gap of 30 dB or more we should think with 70% of confidence about serious lesions. Sensorineural hearing loss (SNHL) was prevalent at 20% of all patients and 18% of COM. The most common form of SNHL was sloping loss. When there were other kinds of pathology at MIDDLE EAR the effect of size of perforations of tympanic membran was not significant.
