内镜结合锁孔技术在微血管减压术中的应用

目的 探讨神经内镜结合锁孔技术在微血管减压术治疗原发性三叉神经痛中的应用.方法 回顾性分析65例应用神经内镜结合锁孔微血管减压术治疗的原发性三叉神经痛患者的临床资料、手术资料及随访结果.手术方式为经乳突后锁孔入路,并在垫入隔片前后均置入神经内镜行多角度观察.结果 1例用神经内镜探查时发现并存的责任动脉,11例内镜探查后调整隔片位置.65例患者中术后62例(95.4%)疼痛消失,2例(3.1%)疼痛减轻,总有效率98.5%.治疗有效的64例均获得随访,随访时间8～55个月,平均34个月.术后3年内2例复发,复发率3.1%.结论 锁孔技术手术创伤小,能减少术后并发症的发生;应用神经内镜探查能避免遗漏责任血管、协助调整隔片位置,提高手术有效性,降低术后复发率.

Application of neuroendoscope and keyhole technique in microvascular decompression

Objective To explore the neuroendoscope-assisted microvascular decompression (MVD) by keyhole approach for the idiopathic trigeminal neuralgia (ITN).Methods The clinical and operation data and follow-up results of 65 patients with ITN underwent neuroendoscope-assisted MVD via keyhole approach were analyzed. Neuroendoscope was used for the exploration via retromastoid keyhole approach before and after the placement of Teflon.Results A coexistent offending artery was found in 1 case and Teflon replacement was...
