摘要
目的探讨大前庭水管语前聋患儿人工耳蜗植入手术方法及可行性,并对术后听觉言语康复效果进行评估。方法回顾性分析2001年7月~2011年9月收治的27例大前庭水管语前聋患儿的临床资料,均为极重度聋或全聋,其中男19例,女8例,年龄1.6~4.0岁,平均2.5岁。均行右耳人工耳蜗植入,于术后6个月行声场测听,测试言语频率平均听阈,开机训练1年后,进行限定词表言语测听及非限定词表言语测听评估听力康复效果。结果 27例患儿中,术中发生"井喷"者4例,经术中采用小块肌肉或筋膜严密封堵电极周围空隙,有效防止了外淋巴漏。术后经开机康复训练6个月后,声场测听言语频率平均听阈为25~30dB nHL,平均27.5±4.5dBnHL;开机训练1年后,限定词表言语测听言语识别率平均为83.3%,非限定词表言语测听言语识别率平均为81.6%。结论大前庭水管语前聋患者可行人工耳蜗植入;术前完善的影像学评估、良好的手术视野以及术中严密封堵电极周围空隙是预防"井喷"及手术成功的关键;术后听觉言语康复效果满意。
