Evaluation of attic retraction pockets by microendoscopy.

Abstract

Attic retraction pockets (RPs) are one of the important sequelae of otitis media with effusion and are classified on the basis of the findings of otoscopy or otomicroscopy. It is unclear when and how RPs turn into cholesteatomas. We compared the findings of RPs obtained with the use of a microendoscope with those from an otomicroscope to determine the extension of RPs.
