儿童言语障碍原因及其与听力减退的量化关系

Quantitative relation between reasons of speech disorder and auditory dysesthesia in children

目的:探讨言语障碍病因及其与听力减退量化关系,为言语康复和听力补偿提供客观准确依据。方法:对各类言语障碍者进行临床及实验室检查,确定他们的病因及其各占比例数。并重点对听性言语障碍者行听性脑干反应(ABR)及40Hz相关电位反应阈dB(SPL)值测试和量化对比。结果:235例各类言语障碍者中有较明显的16种病因。暂找不出有其他病因而仅有听力减退者101例,占全部病例43%。对其中31例量化分析:不同言语障碍类型之间有的听力损失程度平均仅相差12dB左右(P<0.05)。结论:言语障碍原因较多,但仅就结果分析与听力减退有关者即达近半数,且有极大相关性,从量化角度分析他们的相关程度已不囿于ISO的分级关系。

AIM:To explore the quantitative relation of reasons of speech disorder with hearing dysesthesia, and to provide objective and correct evidence for speech rehabilitation and hearing compensation. METHODS:Children with all kinds of speech handicap were included for clinical and laboratory examinations,so as to know the causes of diseases and their percentages,respectively.The auditory speech handicapped were tested by Auditory brainstem response(ABR) and 40 Hz relative potential reaction limen db(SPL) and compared with quantitative relation. RESULTS:There were 16 obvious causes in 235 children with speech disorder,other causes couldn't been found in 101 cases with hypoacusis,which was 43%in all cases,and 31 of them were quantitatively analyzed:some hearing decrease among speech disorder types had deference only about 12 db on average(P< 0.05). CONCLUSION:There are many reasons for speech disorder, and half of them have great relation with auditory dysesthesia,and the correlative level is not less than ISO grades analyzed with quantity.
