The border zone of the surgery of neoplasm arising in and around the ear is the lateral skull base surgery. If the malignant neoplasm involves the middle ear, the mastoid, the dura of the middle or posterior fossa, the carotid artery and the jugular vein, the prognosis drops off significantly. In cases with benign neoplasm, it is sometimes possible to remove them without neurological deficit if the neoplasm involved surrounding area of the temporal bone. Between 1999 and 2001, 13 patients with neoplasm of the external auditory canal and middle ear were treated at the Department of Otolaryngology, Kanazawa University. Seven patients with malignant tumors and 6 patients with benign tumors were registered. Within these 13 cases, two cases (a case with squamous cell carcinoma of the external auditory canal and with giant cell tumor of the temporal bone) were described and discussed about the philosophy of treatment of neoplasm arising from the ear.
