Hypoglossal schwannomas are rare cranial base neoplasms that originate in the posterior cranial fossa and extend through the hypoglossal canal in a dumbell fashion. Recent experience with this unusual neoplasm prompted a search for an operative approach to remove the lesion with a minimization of postoperative morbidity from bleeding and iatrogenic cranial nerve deficits. This report describes the use of the transcondylar approach with monitoring of the lower basal cranial nerves to totally remove a transcranial hypoglossal schwannoma with no new-onset cranial nerve palsies. The regional anatomy of the hypoglossal nerve and canal is reviewed in relation to the operative approach.
舌下神经鞘瘤是一种罕见的颅底肿瘤，起源于后颅窝，并以哑铃状延伸穿过舌下神经管。最近对这种不寻常肿瘤的治疗经验促使人们寻找一种手术方法，以尽量减少因出血和医源性颅神经缺损导致的术后发病率。本报告描述了采用经髁入路并监测低位颅底神经，以完全切除经颅舌下神经鞘瘤且无新发颅神经麻痹的情况。结合手术入路对舌下神经和神经管的局部解剖结构进行了回顾。
