Abstract
Two patients were treated surgically for adenoid cystic carcinoma of the external auditory canal. A 24-year-old woman complained of pain and preauricular swelling. The diagnosis was confirmed by biopsy of the posterior wall of the right external auditory canal. Histopathological study revealed typical tubular type of adenoid cystic carcinoma. She was treated primarily with en bloc resection of the external auditory canal, radical mastoidectomy, parotid gland extirpation and regional lymphnode resection for the purpose of complete surgical removal of the tumor. Thereafter, irradiation was done. The second patient was an 80-year-old man, who complained of earache. The diagnosis was confirmed by biopsy of the anterior wall of the left external auditory canal. Histopathological study revealed cribriform type of adenoid cystic carcinoma. He was treated only with en bloc resection of the external auditory canal because of his age and because his tumor was limited to the cartilagenous part of the external auditoryanal.
