以往多认为起自斜坡或向内耳道生长的桥小舾角肿瘤因受脑干和小脑的限制而不能手术。常规的经枕下,迷路或颅中窝进路不能全部切除肿瘤。六十年代后期,House等试图经腭、斜坡切除肿瘤,阻断肿瘤的血液供应,但因血管易向侧方回缩难于止血,并需经口腔故有感染的潜在威胁而受到限制。本文作者结合1,200多例经迷路切除桥小脑角肿瘤和切除颈静脉球体瘤时面神经改道的经验,开展了经耳蜗进路切除此类肿瘤的 In the past, it was thought that the small squamosular angle tumor arising from the slope or the inward ear canal cannot be operated due to limitations of the brain stem and cerebellum. Conventional suboccipital, labyrinth, or cranial fossa approaches do not completely remove the tumor. In the late 1960s, House and others tried to remove tumors by squatting or sloping and blocked the blood supply to the tumor. However, it was difficult to stop the bleeding because the blood vessels were easily retracted laterally and was limited by the potential threat of oral infection. The authors of this paper combined the experience of more than 1,200 cases of resection of bridge cerebello occlusal tumors and resection of jugular glomus tumors to experience the resection of facial nerves.
