| Abstrakt: | Although hemangiomas are common in the head and neck area, they are uncommon in the temporal bone. External auditory canal (EAC) hemangiomas are a relatively uncommon otologic condition. In the English literature, only 29 cases of temporal bone hemangioma have been reported. We also present the case of a 32-year-old male patient who presented with an 8-month history of decreased hearing, tinnitus, and aural fullness on the right side. Otoscopic examination of the right ear revealed a smooth, oval, well-circumscribed, reddish, pulsatile, nontender mass, which was about 1 cm in diameter and occupied two-thirds of the EAC. It was soft in consistency, compressible, and appeared to be arising from the right posterior-superior portion of the bony canal wall; the tympanic membrane seemed to be uninvolved. The patient had mild conductive hearing loss of the right ear with an average air-bone gap of 20 dB; the left side was normal. High-resolution contrast-enhanced computed tomographic scanning of the temporal bone showed well-defined, rounded, homogenously enhancing lesions at the posterior-superior aspect of right EAC measuring 0.7 × 0.8 cm. Angiography was performed and there was evidence of vascular blush in the region of the right EAC. Three blood vessels were identified and embolized. The mass was completely removed by the endaural approach, and a retroauricular skin graft to restore cutaneous integrity was not required. Histopathology indicated a capillary hemangioma without cytological atypia or mitotic activity. There was no recurrence 1 year after the surgery.
