我们的目的是确定在我们机构的儿童人工耳蜗（CI）植入者中，内耳畸形对手术难度和术后听力结果的影响。我们回顾了1985年至2009年6月间78例连续的儿童CI病例的医疗和听力学记录。30例患者的高分辨率颞骨计算机断层扫描成像可用于回顾性解释。这30例患者中有7例（23%）有耳蜗前庭发育不良。50%的严重异型增生患者术中出现脑脊液涌出，而无异型增生患者的这一比例为13%。在具有可用听力学结局数据的患者中，26例正常/轻度/中度发育不良患者中有17例能够完成CNC测试，而2例重度发育不良患者均无法完成开集测试。我们的经验表明，手术困难和听力结果在小儿CI收件人可能会受到影响的存在和严重程度的耳蜗前庭异常。
Our aim was to determine the influence of inner-ear anomalies on surgical difficulty and postoperative audiologic outcomes among pediatric cochlear implant (CI) recipients at our institution. We reviewed medical and audiologic records from 78 consecutive pediatric CI cases between 1985 and June 2009. Thirty patients had high-resolution temporal bone computed tomography imaging available for retrospective interpretation. Seven of these 30 patients (23%) had cochleovestibular dysplasia. Fifty percent of patients with severe dysplasia had a cerebrospinal fluid gusher intraoperatively, compared with 13% of patients with no dysplasia. Of patients with available audiologic outcome data, 17 of 26 patients with normal/mild/moderate dysplasia were able to complete CNC testing, whereas neither of the 2 patients with severe dysplasia could complete the open set test. Our experience suggests that surgical difficulty and audiologic outcomes in pediatric CI recipients may be affected by the presence and severity of a cochleovestibular anomaly.
