          SUMMARY

          Osteomas as well as exostoses of the internal auditory canal are rare, benign, usually slow-growing lesions. The most common localizations of these temporal bone lesions are the mastoid cortex and the external auditory canal. A rare case is reported of bilateral osseous stenosis of the internal auditory canal, in the absence of clinical (auditory, vestibular and facial nerve) symptoms. In the absence of auditory, vestibular and/or facial nerve symptoms, long-term follow-up should be assessed; surgical intervention may be warranted only if symptoms are present.

          RIASSUNTO

          Gli osteomi e le esostosi del condotto uditivo interno rappresentano una condizione patologica di raro riscontro, benigna e di solito caratterizzata da un lento accrescimento. Le localizzazioni più frequenti di tali lesioni dell'osso temporale sono la corticale mastoidea e il condotto uditivo esterno. Gli autori riportano un raro caso di stenosi bilaterale ossea del condotto uditivo interno, in assenza di sintomi o segni audiologici. In assenza di sintomatologia uditiva, vestibolare o deficit del faciale, è necessario sottoporre il paziente a follow-up a lungo termine, mentre l'opzione chirurgica è da considerarsi solo qualora vi siano manifestazioni cliniche importanti.

              Osteoma of the internal auditory canal.

              We present a case of an osteoma of the internal auditory canal, which was surgically removed with symptomatic improvement. We describe CT, MRI, histological and operative findings, with a review of the proposed aetiology. The implications for imaging in the investigation of retrocochlear lesions are discussed.
