对40例全聋患者行人工耳蜗埋植,19例出现前庭反应,即刻反应16例,迟发反应3例。认为发生前庭反应的因素,前者可能与电极穿破圆窗膜导致外淋巴漏、内外淋巴压力改变和术中行电刺激试验有关,后者可能与应用人工耳蜗过程中反复长期电流刺激前庭神经元有关。但均与电极插入鼓阶的深度和前庭的功能状态无关。 Cochlear implants were implanted in 40 patients with total deafness, 19 cases had vestibular reaction, 16 cases responded immediately and 3 cases delayed reaction. That the occurrence of vestibular response factors, the former may lead to perforation of the round window membrane lead to extralymphatic leakage, changes in pressure inside and outside the row and row of electrical stimulation test, the latter may be associated with the application of repeated long-term current cochlear stimulation vestibular neurons related . But both have nothing to do with the depth of the electrode inserted into the scala tympani and the functional state of the vestibule.
