聋儿助听器佩戴前后听力检测在WHO和ANSI分级标准中的应用

The applied research of WHO and ANSI Grading standard in the Audiometric Tests for the deaf and the Speech Intelligibility Tests for the aided

目的:通过常规的听力检查,对聋儿使用助听器的效果作出评估,结合WHO和ANSI的分级标准,寻找最佳的听障分级。方法:选择中度至极重度感音神经性聋儿17例,均为从小开始佩戴助听器的语前聋儿童,佩戴年龄为15～44月(平均为33月),于相同的聋儿学校进行早期的言语训练。依据世界卫生组织(WHO)及美国国家标准协会(ANSI)的分级标准,分析其使用助听器后的听力测试及言语理解能力测试的结果。结果:WHO和ANSI分级标准在人工耳蜗手术分类结果,一致性较差(P<0.05);WHO和WHO+言语理解能力测试在人工耳蜗的手术分类结果,一致性较差(P<0.05);ANSI和ANSI+言语理解能力测试在人工耳蜗的手术分类结果,一致性较好(P<0.001)。结论:ANSI和WHO的两种分级标准中以ANSI更科学,ANSI能更清晰反映不同程度的听力水平,可以帮助估计聋儿助听器验佩后其言语理能力效果。

Objective：To conclude the relevant assessment by studying the impacts on the deaf children＇ when using the hearing aids through regular inspections, to obtain the best hearing disability grading with the combination of WHO and ANSI grating criterion. Methods： To target at moderate to profound sensorineural hearing loss deaf children＇ s, who are pre-linguistic deafness and have been wearing hearing aids from childhood, of 15 to 44 months （ an average 33 months） , attending early speech training at the same school, with the WHO and ANSI assessment criterions, Totally 17 items： To examine all audiological indexes that derive from the deaf children＇ s aided and unaided and speech intelligibility test results. Results：WHO and ANSI grading criterion is more suitable for the cochlear implant surgery, share result is not uniformity （ P 〈 0.05 ） ; WHO and WHO ＋ Speech Intelligibility test grading criterion is more suitable for the cochlear implant surgery, share result is not uniformity（ P 〈 0.05 ） ; ANSI and ANSI ＋ speech intelligibility test grading criterion is more suitable for the cochlear implant surgery, share the same result in uniformity （ P 〈 0. 001 ）. Conclusions： Within the ANSI and WHO assessment standard, ANSI is more scientific to reflect the different hearing level in a more distinct way. Can help estimate the deaf children with hearing aids processing power of speech after the results of the assessment.
