摘要
目的总结Ⅲ型内耳不完全分隔患者耳蜗植入的临床特点。方法分析10例Ⅲ型内耳不完全分隔患者的临床资料。结果 10例患儿产后检查均为重度感音神经性听力损失,颞骨磁共振及电子计算机断层扫描成像诊断单纯IP-Ⅲ畸形7例、IP-Ⅲ合并大前庭水管综合征1例;IP-Ⅲ合并IP-Ⅱ型耳蜗畸形2例。10例患者均成功植入人工耳蜗,术中井喷9例,术中CT示电极位置均正常,术后超声示皮下均无大量渗液;1~4周内开机调机正常,12个月后听力测试稳定,听阈测试平均为(39.11±6.61)dB HL,语言识别率平均为45%,扬扬格词表平均为61%。结论Ⅲ型内耳不完全分隔患儿植入耳蜗有井喷风险,应做好预防及补救措施,植入耳蜗后随访患者听力恢复效果佳。
