Schwannomas of the lower cranial nerves are rare tumours. We have surgical experience in six patients.
We have retrospectively reviewed the files of the six patients with jugular foramen schwannomas that were treated in multidisciplinary collaboration in the departments of neurosurgery and ENT.
From a clinical point of view, the most important finding was that these tumours usually mimic a vestibular schwannoma. The imaging findings however always allowed the differentiation. The surgical technique included in all cases a suboccipital approach for the intracranial part. When large, the extracranial extension had to be removed through a lateral cervical or transfacial approach. There was no mortality and minor morbidity, with good functional outcome. In subtotally removed tumours, recurrence occurred.
A combined neurosurgical and ENT approach allows for safe removal of these often large skull base tumours.
下颅神经鞘瘤是罕见肿瘤。我们有6例患者的手术经验。
我们回顾性分析了6例经神经外科和耳鼻喉科多学科协作治疗的颈静脉孔区神经鞘瘤患者的病历。
从临床角度来看，最重要的发现是这些肿瘤通常类似前庭神经鞘瘤。然而，影像学表现总能实现鉴别诊断。所有病例的手术技术均包括对颅内部分采用枕下入路。肿瘤较大时，颅外延伸部分必须通过颈外侧或经面部入路切除。无死亡病例，轻度并发症发生率低，功能预后良好。次全切除的肿瘤出现了复发。
神经外科和耳鼻喉科联合入路可安全切除这些通常较大的颅底肿瘤。
