影响语前聋患儿人工耳蜗植入术后前语言交流能力的因素分析

目的 探讨影响语前聋患儿人工耳蜗植入术后前语言交流能力的相关因素.方法 对接受人工耳蜗植入术的语前聋患儿 31例进行随访调查,平均植入年龄为46.71±24.78月,术后1个月开机进行康复训练;采用视频分析法于开机后12个月对患儿的轮流交流、主动交流、视觉交流及听觉注意等进行分析,并根据以下方面分组:按植入年龄分为≤36个月组16例,>36个月组15例;按术前有无正规康复训练(时间超过3个月)分为康复组14例,未康复组17例;按术前残余听力分为≤80 dB HL组6例,>80 dB HL组25例;按术前是否使用助听器(时间超过3个月)分为使用组21例,未使用组10例.应用Wilcoxon秩和检验分析各组前语言交流能力的差别.结果 术前进行康复训练、术前佩戴助听器、术前残余听力好的人工耳蜗植入患儿的前语言交流能力得分高于术前未进行康复训练、术前未佩戴助听器、术前残余听力差的人工耳蜗植入患儿(P<0.05);植入年龄≤36个月组与>36个月组间比较差异无统计学意义(P>0.05).结论 术前残余听力好、佩戴助听器、进行过正规康复训练的语前聋患儿人工耳蜗植入术后其前语言交流能力较好,而植入年龄对其无明显影响.

Factors Affecting the Preverbal Communication Skill in Prelingually Deaf Children with Cochlear Implants

Objective To study the factors affecting preverbal communication skill in prelingually deaf children with cochlear implants.Methods A total of 31 prelingually deaf children with cochlear implantation participated in the study.They received cochlear implantation the age of 12 months with a mean of 46.71 months.The video analysis were applied to assess the preverbal communication skill including rurn-taking,autonomy,eye contact and auditory awareness.According to the implant age,preoperative use of hearing aids,preoperative speech rehabilitation training,preoperative surgerg ear averrage residual hearing.Wilcoxon signed-rank test was used to evaluate the differences among the groups.The implant age distribution:16 cases in ≤36 months group;15 cases in >36 months group.Preoperative speech rehabilitation training (recovery time more than 3 months) : 14 cases in rehabilitation group, 17 case in no rehabilitation group.Preoperative surgerg ear averrage residual hearing:6 cases in ≤80 dB HL group;25 cases in >80 dB HL group.Preoperative use of hearing aids (use time more than 3 months) distribution: 21 cases in use group, 10 cases in no use group.Results There was statistical signifficance in preoperative use of hearing aids,preoperative speech rehabilitation training,preoperative surgerg ear averrage residual hearing(P<0.05)and there was no statistics significance group of implant age(P>0.05).Conclusion Preoperative use of hearing aids,preoperative speech rehabilitation training,preoperative surgerg ear averrage residual hearing in prelingually deaf children with cochlear implants relate with better preverbal communication still.
