通过对37例47耳C型鼓室曲线与声反射二者之间关系的分析证实,在咽鼓管功能不良导致鼓室负压,出现鼓室导抗曲线峰顶左移的同时,还可引起声反射的改变。这种改变包括声反射幅度(mmho=反射前声顺值—反射声顺值)的减弱和声反射的消失。报告如下。
Through the analysis of the relationship between 37 cases of 47-ear tympanogram and acoustic reflex, it is confirmed that while the eustachian tube dysfunction leads to tympanic negative pressure and the tympanogram peak shifts to the left, meanwhile it can cause acoustic reflex Change. Such changes include a reduction in the amplitude of acoustic reflections (mmho = reflectivity before reflectivity - reflectivity of reflectivity) and the disappearance of reflections. The report is as follows.
