目的:探讨外耳道恶性肿瘤的临床特征,诊断、治疗方法。方法:对1987年～1996年间38例外耳道恶性肿瘤进行分析。结果:外耳道恶性肿瘤以鳞癌最常见,59％患者首次手术前误诊为良性疾病;35例患者手术前后结合放疗,3例仅放疗;T_1期肿瘤生存率为66.7％,T_2期为35.7％,7例患者发现远处转移。结论:外耳道恶性肿瘤局部切除和放疗后进行化疗可提高患者的生存率。 Objective: To investigate the clinical features, diagnosis and treatment of external auditory canal malignant tumors. Methods: Thirty-eight cases of external auditory canal malignancy from 1987 to 1996 were analyzed. Results: The most common external auditory canal malignancy was squamous cell carcinoma, 59% of patients were misdiagnosed as benign diseases before the first operation. 35 cases were combined with radiotherapy before and after operation and 3 cases were treated with radiotherapy only.
