青少年语前聋患者人工耳蜗植入术后语言理解能力康复效果评估

Evaluation on the Language Comprehension of Pre-lingually Deaf Adolescents with Cochlear Implants

目的：研究青少年语前聋患者人工耳蜗植入术后语言理解能力康复效果。方法选用《听力障碍儿童听觉语言能力评估标准及方法》中的听话识图项目，对75例7～18岁（男44例，女31例）青少年语前聋患者人工耳蜗植入术前、术后3、6、12个月进行语言理解能力评估，其中，A组：36例，7岁≤年龄＜12岁，术前27例曾佩戴助听器；B组：39例，12～18岁，术前21例曾佩戴助听器。结果75例患者术前语言理解能力为0．75±0．55岁，术后3、6、12个月分别为1．45±0．54、2．23±0．45、3．08±0．41岁，且A组语言理解能力均优于B组。患者性别、术前是否佩戴助听器对术后语言理解能力影响差异无统计学意义（P＞0．05）。结论青少年语前聋患者人工耳蜗植入术后能获得一定程度的语言理解能力改善，且植入时年龄越小、植入时间越长，效果越好；对于超过最佳植入年龄的语前聋青少年，仍建议尽早行人工耳蜗植入。

Objective To investigate the results of the language rehabilitation through the evaluation of the language comprehension of 75 cases of severe to profound pre -lingually deaf adolescents with cochlear implants . Methods Using＂evaluation criteria and methods on hearing and speech ability in deafened children＂as a test mate-rial ,and analyzed the outcome of the language comprehension test .Results The comprehension ability of entire pa-tients increased significantly as time went by .The entire comprehension ability was 0 .75y ,1 .45y ,2 .23y ,3 .08y before operations ,and 3 ,6 ,12 months after operations .The younger ,the more significant the improvements .There was no significant difference in rehabilitation outcomes in genders and wearing no hearing aids .Conclusion Cochlear implants can improve the comprehension ability of pre -lingual deaf adolescents ,and the longer they use implants , the better the results .If being implanted at younger age ,the improvement will be more significant .Patients who were beyond the best age were advised to get implant as soon as possible .
