分析确诊为中耳积液的74例110耳声阻抗测定结果。B型及C_3型鼓室图104耳(94.5％),肯定鼓室图是耳镜检查的有力补充,鼓室图类型与中耳积液量无规律性关系。鼓室压<-1.48kPa者100耳,占90％;声顺值<0.28者73耳,占66.4％。镫骨肌反射均消失。由此提出:鼓室图B型或C_3型、鼓室压<-1.48kPa、声顺值<0.28、曲线坡度<15％、镫骨肌反射消失等五项联合应用,再结合病史,打气耳镜检查,可提高中耳积液早期诊断的准确性,作为普查筛选和诊断渗出性中耳炎的常规辅助方法之一。
Analysis of 74 cases of middle ear effusion confirmed 110 acoustic impedance measurements. Type B and C_3 tympanograms 104 ears (94.5%), sure tympanogram is a strong supplement otoscopy, tympanogram and the amount of irregular middle ear fluid relationship. Tympanic pressure <-1.48kPa 100 ears, accounting for 90%; acoustic compliance <0.28 73 ears, accounting for 66.4%. Stapelgia reflex disappeared. It is proposed that: tympanogram B or C_3 type, tympanic pressure <-1.48kPa, acoustic compliance value <0.28, the slope of the curve <15%, the disappearance of stapedius muscle and other five joint application, combined with medical history, inflatable otoscopy , Can improve the accuracy of the early diagnosis of middle ear effusion, screening and diagnosis of exudative otitis media as a common auxiliary method.
