经鼻内镜鼻咽切除及带血管蒂鼻腔粘膜瓣修复术 治疗T1/T2a和选择后T2b/T3鼻咽恶性肿瘤 陈明远 博士, 副教授 中山大学肿瘤防治中心鼻咽癌科 广州市东风东路651号 Email: chenmy@mail.sysucc.org.cn
研究背景 鼻咽癌首选放射治疗,放疗后单纯局部复发率约10%; 救援性外科治疗是局部复发鼻咽癌最佳治疗手段之一; 鼻咽切除术也是鼻咽腺癌、肉瘤等的治疗方法之一; 鼻外进路:空间大但创伤大 外科切除:广泛切除但操作难度大 消融治疗:操作简便但适应症狭窄 ? 鼻内进路:微创但空间狭窄

结论 创新的经鼻内镜鼻咽切除术治疗rT1/T2a和选择后rT2b/T3期局部复发鼻咽癌微创、安全并且有效; 创新的带血管蒂鼻腔粘膜瓣能有效而微创地修复局部复发鼻咽癌的手术创面; 基于经鼻内镜鼻咽切除术的单纯外科治疗,为部分拒绝放射治疗的高选择后的非鳞癌初治鼻咽恶性肿瘤患者提供一个新的备选治疗方法。
