Osteoma External Auditory Canal
| Description | : | Osteomas of the ear canal are benign tumors which differ from exostoses both clinically and histologically. The osteoma is relatively rare and usually solitary. It may arise from any portion of the bony external canal, although osteomas are usually attached to the tympanosquamous suture line and located close to the isthmus. In this patient, a large osteoma has trapped a mass of cerumen and desquamated keratin causing a conductive hearing loss |
