Abstract

 

Osteomas of the middle ear are rare benign tumors. Their consequences and symptoms are due to their specific location, such as the promontory or the epitympanum and their contact with the facial nerve, the semicircular canal, the ossicles, and the oval or round windows.

We report a very unusual case of middle ear osteoma (MEO) in a 23-year-old male patient causing a right mixed hearing loss by contacting and overwhelming the incus and stapes. The lesion was also closely attached to the tympanic portion of the fallopian canal. Since the stapes was not clearly visible behind the lesion, careful observation was preferred to surgery owing to the high risk of inner ear damage and facial palsy with removal of the lesion.

MEOs are rarely situated at this critical site. Regular clinical and computerized tomography monitoring is warranted to check their growth. This case also supports the etiological theory of chronic middle ear inflammation causing osteomas.
