神经内镜辅助经岩前入路显微手术治疗向后延伸的岩斜区脑膜瘤的疗效

目的 探讨神经内镜辅助经岩前入路显微手术治疗向后延伸的岩斜区脑膜瘤的疗效。方法 回顾性分析2015年7月至2020年1月神经内镜辅助经岩前入路显微手术治疗的13例向后延伸的岩斜区脑膜瘤的临床资料。结果 肿瘤全切除2例，次全切除9例，大部分切除2例。术后症状均有不同程度的缓解。2例术后出现短暂性复视，3个月内完全恢复。术后未出现脑脊液漏、听力损害、颅内出血。术后随访1个月～6.5年，平均2.5年；1例复发，无死亡病例。结论 神经内镜辅助经岩前入路显微手术治疗向后延伸的岩斜区脑膜瘤，效果良好。

Clinical efficacy of neuroendoscope-assisted microsurgery through anterior petroclinal approach for petroclival meningiomas with posterior extension

Objective To investigate the effectiveness of neuroendoscope-assisted microsurgery through anterior petroclinal approach for petroclival meningiomas with posterior extension. Methods The clinical data of 13 patients with petroclival meningiomas with posterior extension who underwent neuroendoscope-assisted microsurgery through anterior petroclinal approach from July 2015 to January 2020 were retrospectively analyzed. Results Total resection of tumors was achieved in 2 patients, subtotal in 9 and greatly partial in 2. Symptoms were relieved in all patients after operation. Transient diplopia occurred in 2 patients after operation, and recovered completely within 3 months. There were no cerebrospinal fluid leakage, hearing damage or intracranial hemorrhage after operation. The postoperative follow-up ranged from 1 month to 6.5 years, with a mean time of 2.5 years. Recurrence of tumor occurred in 1 patient, and there was no death. Conclusions Neuroendoscope-assisted microsurgery through anterior petroclinal approach can obtain good outcmes in patients with petroclival meningiomas with posterior extension.
