We present a 52-year-old male case of right trigeminal neurinoma at lateral cavernous sinus. The tumor was 40 mm in maximum diameter, obviously compressed temporal lobe and encased internal carotid artery. Extradural middle fossa and transcavernous approach was applied and the tumor was resected via Parkinson's triangle. This approach enabled safe and effective tumor resection, sufficient visualization, and operative field ( Figs. 1 and 2 ). We performed dissection of the tumor from trigeminal nerve, tentorium, and middle fossa and resect the tumor around internal carotid artery sufficiently. Postoperative course was good without any new neurological deficit. This surgical method is considered safe and effective for the resection of the tumor at lateral cavernous sinus.

我们报告一例52岁男性右侧海绵窦外侧三叉神经鞘瘤病例。肿瘤最大直径为40毫米，明显压迫颞叶并包绕颈内动脉。采用硬膜外中颅窝和经海绵窦入路，通过帕金森三角切除肿瘤。该入路实现了安全有效的肿瘤切除、充分的视野暴露以及术野（图1和图2）。我们从三叉神经、小脑幕和中颅窝分离肿瘤，并充分切除颈内动脉周围的肿瘤。术后病程顺利，无任何新的神经功能缺损。该手术方法被认为对于切除海绵窦外侧的肿瘤安全有效。视频链接可在：https://youtu.be/2ekuILIgEuo 找到。
