Sixty patients were selected for cochlear implantation and 50 of them received an intracochlear implant (Nucleus). Vestibular function was evaluated before and after surgery using a caloric test and a velocity step test. Sixteen patients had normal or residual vestibular function before surgery, 11 bilateral and 5 unilateral; in 3 of the latter patients, the ear with vestibular areflexia was elected for implantation, which reduced the number of patients at risk for vestibular dysfunction to 13. Vestibular function was preserved in all of these patients except for 4; the risk of vestibular function loss can therefore be rated at about 31%.
60名患者被选作人工耳蜗植入对象，其中50名接受了鼓室内植入（Nucleus）。术前和术后使用冷热试验和速度阶跃试验对前庭功能进行评估。16名患者术前前庭功能正常或有残余功能，其中11名双侧正常，5名单侧正常；在这5名单侧正常的患者中，有3名选择在前庭无反射的耳进行植入，这使得前庭功能障碍风险患者数量降至13名。除4名患者外，所有这些患者的前庭功能均得以保留；因此，前庭功能丧失的风险可评定为约31%。
