Abstract
|
|
|
Malignant tumors of the external auditory canal (EAC) are uncommon. It is a rare malignant neoplasm with an aggressive nature and an overall poor prognosis. The primary goal of the treatment of EAC tumors is to remove the primary tumor without recurrence and with maximal preservation of function. At this point, lateral temporal bone resection can achieve
preservation of hearing and facial nerve function when the tumor is confined to the EAC. We report two cases of squamous cell carcinoma of EAC treated by lateral temporal bone resection. In the first case, the patient underwent surgery, and subsequently he underwent radiotherapy. In the second case, the patient underwent only surgical treatment without
radiation therapy. The 2 patients showed no evidence of recurrence during the follow-up period. In this report, we compare treatment of malignant tumors limited to the EAC by lateral temporal bone resection only and surgery with adjuvant radiotherpy.
