宽频声导抗测试声能吸收率对儿童分泌性中耳炎诊断的研究
Research the diagnosis of wide band acoustic absorbance in children otitis media with effusion
摘要
Abstract
Objective To research the diagnostic value of the wide band acoustic absorbance rate in children otitis media with effusion. Methods The wide band acoustic absorbance rate was tested in 114 children (a control group of 30 healthy children;50 patients shown middle ear effusion during tympanotomy;and 34 patients with chronic effusion shown no middle ear effusion during tympanotomy).The data of each group were analyzed, and the diagnostic value of wide band absorbance was analyzed with the receiver operating characteristic curve.Results The wide band acoustic absorbance rate of otitis media with effusion group was notably lower than that of non-effusion group and control group at the 0.5～4 kHz averaged absorbance (P＜0.05).After analyzing the receiver operating characteristic curve, it showed that the diagnosis value was highest in the range of 0.5～2 kHz (area under the curve0.984), followed by 1 kHz and 1.5 k Hz (area under the curve:0.973 and 0.967). Conclusion Compared with the conventional 226 Hz tympanometry, the wide band tympanometry is more accurate for the diagnosis of children otitis media with effusion.It can be used as a better method for the diagnosis of otitis media exudative lesions.关键词
