Case Discussion
External auditory canal osteoma is a slow growing benign neoplasm involving the temporal bone comprising of discrete and pedunculated bone lesion arising along the tympano-squamous suture 1.
They need to be differentiated from exostoses of external auditory canal, which are often bilateral, bony elevations involving the tympanic bone 2.
