语前聋人工耳蜗植入儿童术后1年言语识别能力分析

Analysis of Speech Recognition Ability in Children with Prelingual Deaf Cochlear Implant After 1 Year

目的探讨语前聋人工耳蜗植入儿童不同阶段言语识别能力的发展变化规律。方法选择2013~2015年度“七彩梦行动计划”语前极重度听障儿童70例,均行人工耳蜗植入和听觉口语法康复训练,按照年龄将其分为1~3岁组和4~6岁组,采用《听障儿童听觉语言能力评估标准及方法》比较两组术前及术后开机3、6、12个月时声母识别、韵母识别、双音节识别和短句识别能力。结果①术后开机3、6、12个月,两组儿童声母、韵母、双音节识别和短句识别能力均随康复时间的延长而提高;②1~3岁组术后的声母、韵母和双音节识别率均高于4~6岁组,但短句识别率低于4~6岁组,差异有统计学意义(P<0.05);③儿童的韵母识别率均高于声母识别率,差异有统计学意义(P<0.05)。结论手术年龄和术后康复时间是影响语前聋人工耳蜗植入儿童康复效果的重要因素;对于人工耳蜗植入儿童,声母比韵母难掌握,手术年龄越小,声母、韵母和双音节识别率提高的越快。

Objective To discuss the developmental characteristics of speech recognition in pre-lingual deafness children with cochlear implants over different period of time.Methods Choosing from the 2013-2015"Colorful Dream Action Plan"70 pre-lingual children with extremely severe hearing impairment,all of whom received cochlear implant and auditory oral grammar rehabilitation training.According to age,they were divided into 1~3 years old group and 4~6 years old group.Using"Assessment Standards and Methods for Hearing and Language Ability of Hearing Impaired Children",the two groups were compared with the initial recognition at 3,6,and 12 months before and after the operation finals recognition,double syllable recognition and short sentence recognition capabilities.Results①At 3,6,and 12 months after the operation,the initials,finals,disyllabic recognition and short sentence recognition ability of the two groups of children improved with the extension of the rehabilitation time;②The initials,finals and disyllabic syllables of the 1 to 3 years old group after surgery the recognition rate was higher than that of the 4-6 year old group,but the short sentence recognition rate was lower than that of the 4-6 year old group,the difference was statistically significant(P<0.05);③The recognition rate of vowels of the two groups of children was higher than the recognition rate of initials,the difference was statistically significant(P<0.05).Conclusion Operating age and postoperative recovery time are important factors affecting the rehabilitation effect of prelingual deaf cochlear implant children;for cochlear implant children,initials are more difficult to master than finals.The younger the surgical age,the recognition rate of initials,finals and disyllables The faster you improve.
