The main objectives of microsurgery for vestibular schwannoma are total tumor removal and preservation of facial and cochlear nerve function. For giant tumors, total tumor removal and facial nerve function preservation are challenging. The semisitting position has some advantages. In this video the authors show the removal of a giant vestibular schwannoma with the patient in a semisitting position. They demonstrate the advantages of the semisitting technique, such as the two-handed microsurgical dissection technique and a clear operative field. Finally, a small residual tumor in the internal auditory canal was removed by endoscopy. The patient's facial function was House-Brackmann grade I at discharge.

前庭神经鞘瘤显微手术的主要目标是完全切除肿瘤并保留面神经和听神经功能。对于巨大肿瘤，完全切除肿瘤并保留面神经功能具有挑战性。半坐位有一些优势。在本视频中，作者展示了在患者处于半坐位时切除巨大前庭神经鞘瘤的过程。他们展示了半坐位技术的优势，如双手显微手术解剖技术和清晰的手术视野。最后，通过内镜切除了内听道内的一小部分残留肿瘤。患者出院时面部功能为House-Brackmann I级。视频可在此处查看：https://stream.cadmore.media/r10.3171/2021.7.FOCVID2176 。
