Microsurgical treatment of trigeminal neurinoma under frontotemporal arch-subtemporal approach

CHEN Dong , SHI Jun-Wei , XIONG Wen-de ［目的］探讨经额颞-颞下入路对中颅凹型三叉神经鞘瘤的手术优点。［方法］回顾分析5例经额颞-颞下入路手术切除中颅凹型三叉神经鞘瘤临床资料。4例全切，1例大部切，海绵窦内有残留。2例断颧弓。［结果］术后病人临床症状不同程度改善，其中1例病人术后出现一过性动眼神经麻痹，术后1月恢复；1例出现脑脊液漏，经抗炎治疗和腰大池置管引流痊愈。本组无死亡病例。1例大部切病人术后行γ刀治疗，复查MRI，残存肿瘤无增大。［结论］经额颞-颞下入路对切除中颅凹型三叉神经鞘瘤具有创伤小，距离近，显露好等优点。 三叉神经鞘瘤 Abstract: ［Objective］To investigate the effect in middle cranial fossa trigeminal neurinoma under frontotemporal arch-subtemporal approach.［Methods］Five patients with trigeminal neurinoma resection via subtemporal approach were retrospectively analyzed.［Results］Total resection was achieved in 4 patients and subtotal resection was performed in 1 patient with small portion neurioma remained in the cavernous sinuses. The cranial nerve deficits were improved after operation. Transient oculomotor paralysis happened in 1 case. Leakage of cerebrospinal fluid occurred in another patient, which was fully recovered by lumber draining and antibiotic therapy.［Conclusion］Subtemporal approach can provide better exposure of these tumors with minimal brain retraction. The treatment for middle cranial fossa trigeminal neurinoma is complete microsurgical removal of the tumor through frontotemporal arch-subtemporal approach.
