Özet:

Cholesteatoma frequently results in destruction of the ossicles and the surrounding structures. The most frequent consequence is erosion of the long process of the incus, however, necrosis may be observed anywhere along the ossicular chain. Isolated destruction of the short process of the incus is an extremely unusual condition. In this study, we describe a patient who presented with otorrhea and hearing impairment. The diagnosis of attico-antral cholesteatoma was established and surgery was performed. During surgery, it was observed that the ossicular chain was intact with the exception of an absent short process of the incus. In the odiometric analysis of the patient 6 months post-operatively, the air-bone gap had recovered from 15 dB preoperatively to a postoperative hearing threshold with an average of 5dB at the airline as well as the boneline. This case opens up new dimensions in the discussion of whether the incus short process contributes to hearing.
