Abstract:

Excluding those of the external ear canal, most temporal bone osteomas are found in squama and mastoid. Osteomas of the internal auditory canal are rare and seldon symptomatic. There are, however, some case reports with compression of the eighth nerve causing vertigo, tinnitus, and hearing loss; therefore, they all require clinical and radiological follow-up. Theoretically, compression of the seventh nerve is also possible, although, to the best of our knowledge, it's nerver been reported. We present a case of an osteoma of the internal auditory canal with sudden sensorineural hearing loss and tinnitus.
