Shilpi Sujata | Kapil K. Singh | Amrit P. Singh

Abstract: Osteoma of external auditory canal is benign overgrowth. The incidence of osteoma of temporal bone is very low. Osteomas of external ear commonly present as bony outgrowth originating from tympanomastoid or tympanosquamous suture lines near the bony and cartilagenous junction. Osteomas are usually single, slow growing, unilateral tumors. osteomas are slow growing tumors, asymptomatic when small in size. Small size osteomas can be removed via trans canal approach or the larger one with broad base via postaural approach. The patient described in this case report underwent surgery due to symptoms of conductive hearing loss in right ear. The patient got immediate relief in symptoms after surgery and in follow up, there was no hearing loss on pure tone audiometry and no recurrence seen after 3 months.
