Tumors at the petrous apex are associated with a variety of symptoms, which most often involve the trigeminal nerve. The authors present a rare case of a small epidermoid tumor in Meckel's cave that caused medically refractory trigeminal neuralgia. The surgical challenge associated with approaches to such lesions is discussed. The skull base tumor was excised completely through a small temporal craniotomy. The practicality of neuronavigation in reaching the petrous apex using a small extradural window is presented.
岩尖部肿瘤会引发多种症状，其中最常见的是累及三叉神经。作者报告了一例罕见病例，即位于 Meckel 腔内的小型表皮样囊肿导致药物难治性三叉神经痛。文中讨论了针对此类病变的手术入路所面临的挑战。通过小型颞部开颅术完整切除了颅底肿瘤。介绍了使用小型硬膜外窗口借助神经导航到达岩尖部的可行性。
