Vestibular schwannoma (acoustic neuroma) most commonly presents with ipsilateral disturbances of acoustic, vestibular, trigeminal and facial nerves. Presentation of vestibular schwannoma with contralateral facial pain is quite uncommon.
Among 156 cases of operated vestibular schwannoma, we found one case with unusual presentation of contralateral hemifacial pain.
The presentation of contralateral facial pain in the vestibular schwannoma is rare. It seems that displacement and distortion of the brainstem and compression of the contralateral trigeminal nerve in Meckel's cave by the large mass lesion may lead to this atypical presentation. The best practice in these patients is removal of the tumour, although persistent contralateral pain after operation has been reported.
前庭神经鞘瘤（听神经瘤）最常见的表现是同侧听觉、前庭、三叉神经和面神经功能障碍。前庭神经鞘瘤表现为对侧面部疼痛的情况相当罕见。
在156例接受手术治疗的前庭神经鞘瘤病例中，我们发现1例表现异常，出现对侧面部疼痛。
前庭神经鞘瘤出现对侧面部疼痛的情况很罕见。似乎是脑干的移位和变形以及巨大肿块病变对梅克尔腔中对侧三叉神经的压迫可能导致这种非典型表现。尽管有报道称术后对侧疼痛持续存在，但对这些患者的最佳治疗方法仍是切除肿瘤。
