目的:探讨唇腭裂术后患儿的听力学特征。方法:对62例唇腭裂术后患儿进行DPOAE、ABR和声导抗检查,分析其听力学检查结果。结果:以ABR阈值为诊断标准,诊断为听力异常者共51耳,以轻度和中度异常为主;63耳鼓室导抗图异常,表现为不同程度的中耳功能障碍;26耳DPOAE检查未通过。结论:唇腭裂术后患儿听力异常的比例高。3种客观听力学检查方法在唇腭裂术后的患儿检查中具有高度一致性。
Objective: To investigate the audiological features of children with cleft lip and palate. Methods: Sixty-two children with cleft lip and palate postoperatively underwent DPOAE, ABR and acoustic impedance tests, and their audiological findings were analyzed. Results: ABR threshold was used as the diagnostic criteria, 51 ears were diagnosed as abnormal hearing, with mild and moderate abnormalities as the main diagnostic criteria. 63 were abnormal echocardiogram, which showed different degrees of middle ear dysfunction. 26 ears DPOAE Did not pass. Conclusion: The rate of abnormal hearing in children with cleft lip and palate is high. Three objective methods of hearing tests in children with cleft lip and palate postoperative examination with a high degree of consistency.
