Abstract:
We present a case of osteoma that was diagnosed incidentally in the middle ear. Osteomas are benign tumors and may occur as a solitary lesion in the squama, mastoid, middle ear and petrous pyramid. Even though osteomas in the middle ear are extremely rare, those lesions may be one of the causes of the conductive hearing loss by impinging upon the ossicular chain. There are only 22 cases of osteoma reported in the medical literature to date. In most patients, the diagnosis is confirmed by CT scan or at the time of surgery. CT scanning of these disorders is very useful, especially in examining the extent of the lesion and detailed bone destruction.
