目的:探讨外耳道腺样囊性癌的临床及病理特点,以提高诊断和治疗水平。方法:回顾性分析6例外耳道腺样囊性癌患者的临床表现、治疗及随访结果,其中5例行颞骨次全切除术(含外耳道全切除),1例行外耳道后下壁广泛切除及鼓室成形术。结果:全部患者术后随访8~21个月无复发。结论:外耳道腺样囊性癌生长缓慢,可长期带瘤生存,但远期预后不佳,首次治疗应该采用扩大根治性手术以提高治愈率。
Objective: To explore the clinical and pathological features of external auditory canal cystic carcinoma in order to improve the diagnosis and treatment. Methods: The clinical manifestations, treatment and follow-up results of 6 cases of extra-ductal adenoid cystic carcinoma were retrospectively analyzed. Five cases underwent subtotal temporal resection (including external auditory canal resection), one case underwent extensive resection of the inferior wall and the tympanic cavity Angioplasty. Results: All patients were followed up for 8 to 21 months without recurrence. Conclusion: Adenoidoid cystic carcinoma of the external auditory canal grows slowly and can survive for a long time. However, the long-term prognosis is poor. The first radical treatment should be extended radical surgery to improve the cure rate.
