A 51-year-old woman had a traffic accident on Nov. 15, 1973. She complained of the tinnitus and loss of hearing on the left side on Dec. 10, 1973. She was referred to this hospital on Jan. 29, 1974. Her audiogram showed a hearing loss for the lower frequencies on the left side. A roentgenologic examination revealed considerable increased density in the left external auditory canal. A red membrane, resembling granulation tissue, appeared at the bottom of the canal adjacent to the drum and coalescent with it at the anterior part of the drum. It was removed. The tinnitus was disappeared after the operation, but the loss of hearing was severer after the operation. Histologically the tumor was diagnosed as the capillary hemangioma.
