作者回顾了136例侵及外耳道及颞骨的恶性肿瘤患者,其中多数过去曾接受过治疗,因肿瘤复发而就医。其中鳞状细胞癌85例,基底细胞癌39例,涎腺癌12例。根据肿瘤侵及的范围将患者分为三组。第1组:肿瘤侵及耳甲腔及/或外耳道软骨部,共76例。5例行放疗,71例作广泛切除,五年生存率57％。第2组:肿瘤侵及颞骨表面部分,包括骨性外耳或乳突皮质区,共22例。
The authors reviewed 136 patients with malignant tumors that invaded the external auditory canal and sacrum, most of whom had received treatment in the past and had sought medical attention because of recurrent tumors. There were 85 cases of squamous cell carcinoma, 39 cases of basal cell carcinoma, and 12 cases of parotid adenocarcinoma. Patients were divided into three groups according to the extent of tumor invasion. The first group consisted of 76 tumors invading the concha and/or cartilage of the external auditory canal. Five patients underwent radiotherapy and 71 underwent extensive resection. The five-year survival rate was 57%. Group 2: The tumor invaded the surface of the sacrum, including the osseous outer ear or mastoid cortex, a total of 22 cases.
