Abstract
Osteomas of the external auditory canal are considered clinically to be discrete, benign, pedunculated bone lesions arising along the tympanosquamous suture. They present as solitary, unilateral, and slow-growing tumors. It is usually asymptomatic, but symptoms can arise if a canal obstruction occurs. We report an osteoma occurring in the external auditory canal of a 14-yearold female patient who presented to the ENT Outpatient clinic with a 1-year history of progressive hearing loss affecting the right ear. On physical examination, the right external auditory canal was completely occluded by a hard mass, which was fixed and covered with wax. The Osteoma was removed surgically through the transcanal approach. Histopathological findings confirmed osteoma.
