摘　　要：目的:分析腭裂患儿脑干听力阈值特征。方法:使用电反应测听法检测120例腭裂患儿听力阈值,采用分组对照研究,进行X2检验。结果:①240耳中141耳听力阈值异常,听力障碍发生率为58.8%;②Ⅱ°与Ⅲ°腭裂患儿听力障碍发生率有极显著性差异,P<0.005;腭裂程度与听力障碍程度之间无相关性,P>0.75;③3岁前后比较,听力障碍发生率差异极显著,P<0.005,3～6岁与>6岁比较无显著差异,P>0.05。结论:①58.8%腭裂患儿存在不同程度听力障碍;②腭裂程度越重听力障碍发生率越高,但与听力障碍程度无相关性;③患病年龄越小听力障碍发生率越高,3岁前后有极显著性差异。Objective： To study the characteristics of brainstem auditory threshold in children with cleft palate. Method： The auditory threshold of 120 children with cleft palate were detected by electrical response audiometry. The results were compared with Χ^2 test. Results： The incidence of hearing loss was 58. 8% （141/240） and the difference of that between children with Ⅱ° and Ⅲ° cleft palate was very significant （P 〈 0. 005） ; There was no correlation between the degree of cleft palate and that of hearing loss （P≈0. 75） ： the difference of incidence of hearing loss between the children under 3 years old and the one over 3 years old was very significant （P 〈 0. 005）. There was no significant difference between the hearing loss of the children with 3 - 6 years old and the one over 6 years old （P 〉 0. 05）. Conclusion： 58.8% of children with cleft palate had hearing damage. The more severe the degree of cleft palate was, the higher incidence of hearing damage was. But there was no correlation between the degree of cleft palate and that of hearing loss. The smaller age in children with cleft palate was, the higher incidence of hearing damage was. The difference of incidence of hearing loss between the children under 3 years old and the one over 3 years old was very significant.
