目的 :总结手术治疗外耳道囊性腺样癌的疗效。方法 :回顾分析 1 978至 1 995年收治的外耳道囊性腺癌 1 2例的临床资料。结果 :4例术前病理诊断为耵聍腺瘤 ,行单纯肿瘤切除术 ,术后 2～ 8年复发 ,分别行 2～ 4次手术 (乳突根治、下颌骨切除、颞骨次全切除术 ) ,术后病理诊断为囊性腺样癌 ,术后随访 2～ 8年 ,1例死亡。 6例术前诊断为囊性腺样癌 ,其中 2例行乳突根治术 ,1例行乳突根治加腮腺切除术 ,3例行颞骨次全切术 ,随访 2～ 1 0年 ,2例死亡。 2例术前未行病理检查 ,行单纯肿瘤切除术 ,2～ 3年后复发再行乳突根治术 ,术后病理诊断为囊性腺样瘤 ,随访 5年无复发。结论 :早期就诊和彻底手术是治疗外耳道囊性腺样癌延长患者生命的关键。
Objective: To summarize the curative effect of surgical treatment of cystic adenoid carcinoma of external auditory canal. Methods: The clinical data of 12 cases of external auditory canal adenocarcinoma admitted from 1978 to 1995 were retrospectively analyzed. Results: Four cases of Adenocarcinoma were diagnosed preoperatively and underwent simple tumor resection. The recurrence was performed 2-8 years after operation. The operation was performed on 2 to 4 surgeries (radical mastectomy, mandibular resection and subtotal resection of the temporal bone) Postoperative pathological diagnosis of cystic adenoid carcinomas, followed up for 2 to 8 years, 1 patient died. Six cases were diagnosed cystic adenoid carcinomas preoperatively, including 2 cases of radical mastoidectomy, 1 case of radical mastoidectomy and parotidectomy, and 3 cases of subtotal temporal bone resection. The patients were followed up for 2 to 10 years and 2 died . Two cases had no preoperative pathological examination, simple tumor resection, 2-3 years after the recurrence of radical mastoidectomy, postoperative pathological diagnosis of cystic adenoidosis, no recurrence after 5 years of follow-up. Conclusion: Early treatment and thorough surgery are the key to prolonging the life of patients with external auditory canal adenoid carcinoma.
