Between 1980 and 2006, 20 patients with malignant tumors of the external auditory canal and middle ear were treated at the Department of Otolaryngology, Shiga University of Medical science. Eleven patients with tumors of the external auditory canal and nine patients with tumors of the middle ear were registered. Lymph nodes metastasis and distant metastasis were not observed in all cases. In the external auditory canal tumors, partial resection of the external auditory canal was performed in one case, total resection of the external auditory canal in 4 cases, and partial temporal bone resection in 6 cases. No recurrence was noted in all cases with external auditory canal tumor by the en bloc resection. Surgical treatments were performed in five of nine patients in the middle ear tumors, radical mastoidectomy in three cases, partial temporal bone resection in one case, curettage of the tympanic tumor in one case. The prognosis of the middle ear tumors was very poor. Only the case that enforced curettage in tympanic tumor was alive. For the treatment of malignant temporal bone tumor, the precise diagnosis of the tumor involvement and en bloc surgical resection is important.
