Presentation
Growth in the right external auditory meatus and partial conductive hearing loss
Patient Data
Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.
A single pedunculated bony growth arises from the posterior wall of the right external auditory meatus at the tympanomastoid suture line causing narrowing of the external auditory canal. Imaging features are suggestive of extracanalicular osteoma.
Osteoma is shown in red color, its pedunculated and obstructing the EAM.
Case Discussion
Extracanalicular osteomas of the temporal bone are rare, slow-growing, benign neoplasms. Although they may occur anywhere in the temporal bone, they are most common in the mastoid area. Often, symptoms are negligible and treatment is unnecessary. However, surgical removal is indicated when growth of the osteoma causes distressing symptoms or cosmetic issues.
