Osteoma in the external auditory canal is an uncommon benign lesion, which presents as a solitary, unilateral, and slow-growing pedunculated mass in the outer half of the bony canal.

It is usually asymptomatic, but symptoms can arise if a canal obstruction occurs.

Osteomas of the middle ear are rare lesions.

These are small, single, usually unilateral, peduncular growths, off-white in colour, with smooth  or multilobular surface, asymptomatic or causing functional disorders (progressive hearing loss, pathological appearance of the eardrum, vertigo and otorrhea), of unclear or unknown etiology.

Histopathologically, the osteoma of the middle ear is much the same as an external auditory canal osteoma.
