【摘要】：目的:探讨单侧人工耳蜗植入聋儿声电双模式下听觉康复效果及特点。方法:将36例行单侧人工耳蜗植入的双耳重度-极重度耳聋的婴幼儿随机分配到单纯人工耳蜗植入组(A组,18例)及单侧人工耳蜗加对侧耳助听器组(B组,18例),在康复3个月(T1)、6个月(T2)、12个月(T3)时间点对2组聋儿分别进行声场助听听阈评估、音节要素识别(韵母识别、声母识别、声调识别)及词语识别率(单音节识别、双音节词识别、三音节识别)和选择性听取等测试。结果:T2测试时间点B组500 Hz助听听阈低于A组,T3测试时间点B组500、1 000Hz助听听阈均低于A组(P0.05)。T1测试时间点A组音节要素的3项评估指标、单音节识别率及双音节识别率均高于B组(P0.05),2组在T2测试时间点音节要素及词语识别的3项评估指标均差异无统计学意义(P0.05)。在T3测试时间点B组的声母识别率及声调识别率、双音节及三音节识别、双音节词选择性听取能力均高于A组(P0.05)。结论:人工耳蜗植入聋儿声电双模式的优势会随康复进程逐渐显现,应充分利用双耳聆听的优势,采用最适宜的助听模式。
[Abstract]:Objective: to investigate the effects and characteristics of auditory rehabilitation in deaf children with unilateral cochlear implantation. Methods: Thirty-six infants with unilateral cochlear implantation were randomly assigned to cochlear implant group (group A, n = 18) and unilateral cochlear implantation plus contralateral hearing aid group (group B, n = 18). At the time points of 3 months (T1), 6 months (T2), 12 months (T3) of rehabilitation, the deaf children in the two groups were evaluated for the threshold of sound field hearing aid, the recognition of syllable elements (vowel recognition, consonant recognition). Tone recognition), word recognition rate (monosyllabic recognition, two-syllable word recognition, three-syllable recognition) and selective listening. Results: at T 2 test time point B group 500 Hz hearing aid threshold was lower than A group, and T 3 test time point B group 5001 000Hz hearing aid threshold was lower than A group (P0.05). The rate of monosyllabic recognition and double syllable recognition was higher than that of group B (P0.05). There was no significant difference in the three evaluation indexes of syllable elements and word recognition between the two groups at T2 test point (P0.05). The initial recognition rate, tone recognition rate, two-syllable and three-syllable recognition and selective listening ability of binosyllabic words in group B were higher than those in group A at T3 test time point (P0.05). Conclusion: the advantages of acoustic and electric double mode of cochlear implantation in deaf children will gradually appear with the rehabilitation process, and the most suitable hearing aid mode should be used to make full use of the advantages of binaural listening.
