摘要

目的分析蜗神经管狭窄患者人工耳蜗植入术(cochlear implantation,CI)后康复效果。方法对30例术前颞骨高分辨率CT诊断为蜗神经管狭窄的双耳极重度感音神经性聋患者术中和CI术后3、6、9个月行听神经复合动作电位(evoked compound action potential,ECAP)和电刺激脑干诱发电位(evoked auditory brainstem response,EABR)检测,并于术前、术后3、6、9个月行声场测听,其中17例3岁以上(含3岁)患者行封闭式言语识别率测试,分析其听觉康复效果。结果 130例患者术后3、6、9个月ECAP和EABR的波形均无明显变化。2术后3、6、9个月声场听阈分别为65±8、62±4、61±7dB HL,较术前(100±5dB HL)明显改善。317例术后3、6及9个月的单韵母识别率分别为55%±7%、56%±8%、80%±4%,术后9个月时较术前(52%±8%)明显改善;单声母识别率分别为9%±3%、8%±4%、9%±2%,较术前(8%±2%)无明显改善。结论双侧蜗神经管狭窄患者CI术中、术后ECAP与EABR检测均不能引出典型波形,术后主观听力及言语识别率较差,语言交流存在障碍。
