![]() The mass was excised under general anaesthesia through a postauricular approach. High resolution computed tomography of the Temporal bone revealed a bony outgrowth 7x7mm in the Rt. A pure tone audiogram revealed 35 db conductive hearing loss while the other ear was normal. The almost complete occlusion of the EAC did not enable examination of the tympanic membrane. It was non tender, firm, did not bleed on touch and the probe could be passed anteriorly, inferiorly but not postero- superiorly. A physical examination revealed that the right EAC was almost completely occluded by a single, about 0.5x0.5cm, pinkish, spherical, pedunculated polypoidal mass arising from the postero-superior wall. He denied ear pricking, trauma or swimming. There was no history of ear discharge, ringing in the ears, vertigo or earache. Case ReportĪ 18 year-old man presented to the ENT Outpatient Department with decreased hearing and aural fullness in the right ear for one and a half year. A brief review of the literature follows thereafter. A case of osteoma of the EAC in an eighteen years old male mimicking an aural polyp is being reported. Osteomas presenting as a polyp have rarely been reported in the literature. Aural polyps are commonly a consequence of chronic suppurative otitis media, tuberculous otitis media or neoplastic as in adenoma or a carcinoma. It may rarely present with conductive hearing loss, recurrent otitis externa, headache or a mass in the EAC. Because it is solitary, unilateral and slow-growing, it usually is asymptomatic and discovered incidentally. Osteomas have been described in all regions of the temporal bone, including the middle ear, internal auditory canal, semicircular canals, squamous temporal bone, mastoid and in the external auditory canal. In the head and neck, they most often arise in the fronto-ethmoidal region and rarely in the temporal bone. An osteoma of the external auditory canal (EAC) is an uncommon benign tumor with an incidence estimated to be 0.05% of total Otologic surgery.
