低频和高频探测音鼓室声导抗测试在诊断婴儿中耳功能异常中的作用分析

Low Frequency and High Frequency Probe Tone Tympanic Cavity Acoustic Immittance Test in the Diagnosis of Middle Ear Dysfunction in Infants

目的分析低频和高频探测音鼓室声导抗测试在诊断婴儿中耳功能异常中的作用。方法收集我院诊治的15例(20耳)中耳功能异常患儿,同期收集中耳功能正常的小儿15例(30耳),纳入对象均进行低频(226 Hz)和高频(1 000 Hz)探测音鼓室声导抗测试,测试结果进行对比分析。结果 226 Hz(低频)正常组与异常组多项指标差异无统计学意义(P>0.05);1 000 Hz(高频)异常组多见无锋型,检测结果分析对诊断中耳功能异常的准确度较高。结论高频探测音鼓室声导抗测试能辅助诊断婴儿中耳功能异常,而低频探测音鼓室声导抗测试却不能提供出准确诊断信息。

Objective To analyze low frequency and high frequency probe tone tympanic cavity acoustic immittance test in the diagnosis of abnormal middle ear function of baby. Methods To collect the hospital make a diagnosis and give treatment of 15 cases （20 ears） children with abnormal middle ear function, at the same time to collect normal middle ear function of pediatric 15 cases （30 ears）, its objects were to take low frequency （226 Hz） and high frequency （1 000 Hz） detection of tympanic cavity acoustic immittance test, the test results were analyzed. Results 226 Hz （low frequency） of normal and abnormal group multiple indicators had no significant difference （P 〉 0.05）. 1 000 Hz （high frequency） abnormal group had no obvious frontal type, and the accuracy of the results was high. Conclusion High frequency probe tone tympanic cavity acoustic immittance test can auxiliary diagnosis of dysfunction of middle ear, and low frequency probe tone tympanic cavity acoustic immittance test was not able to provide the accurate diagnostic information.
