本文对406例儿童作声阻抗测试。测试结果,A 型鼓室图226例,其中124例声反射阈值在正常范围内,142例声反射阈值不是提高就是消失,占全部受检者的65.51%。B 型27例,占6.65%,其声反射全部消失。C 型83例和As 型29例,前者占20.44%,后者占7.14%,均发现少数几耳或某一频率,出现声反射阈值提高。作者认为,声阻抗测试在临床上只能作为听力学方面的一种重要的辅助诊断工具。
In this paper, 406 cases of children for acoustic impedance test. Test results, type A tympanogram of 226 cases, of which 124 cases of acoustic reflex threshold in the normal range, 142 cases of acoustic reflex threshold is not increased or disappeared, accounting for 65.51% of all subjects. B type in 27 cases, accounting for 6.65%, the acoustic reflex disappeared. 83 cases of type C and 29 cases of type As, the former accounted for 20.44%, the latter accounted for 7.14%, found a few ears or a certain frequency, the threshold of acoustic reflex appears increased. The authors believe that the acoustic impedance test clinically only as an important audiology diagnostic tools.
