Solitary Osteoma of the External Auditory Canal Causing Conductive Hearing Loss: A Case Report

Osteomas of the external auditory canal (EAC) are rare, benign bony tumors that may remain asymptomatic or cause conductive hearing loss when large enough to obstruct the canal. We report a case of a young adult male presenting with progressive hearing impairment secondary to a solitary osteoma obstructing the right EAC. Clinical examination, pure tone audiometry, and computed tomography (CT) enabled diagnosis. The imaging features and differential diagnoses are discussed, emphasizing the role of surgical resection in symptomatic cases.
