INTRODUCTION: Our aim is to determine the incidence of the contralateral ear (CLE) pathologies in patients with chronic otitis media (COM) and to review the literature.
METHODS: Total of 271 patients who had been diagnosed as having COM with or without cholesteatoma were evaluated. Pathologic alterations such as tympanic membrane perforations, adhesive otitis, cholesteatoma, retraction pockets, and tympanosclerosis in the CLE were determined.
RESULTS: Of all patients, 39.1 % had pathologic alterations in their CLE. The 60.9% of the CLE s were normal. The most frequent finding in these patients was dry perforation of the tympanic membrane (26.9%). The remaining pathologies were retractions (7.3%), cholesteatoma (1.9%), sclerosis (2.2%), and adhesive otitis media (0.7%).
DISCUSSION AND CONCLUSION: A considerable percentage of the CLE s of the patients with COM were affected with a spectrum of pathologies at some degree.
