The purpose of this investigation was to evaluate the sensitivity and specificity of the following acoustic-immittance protocols and their constituent measures for detection of middle-ear effusion in children: (a) tympanometric width; (b) absent ipsilateral acoustic reflex; (c) ASHA guidelines; (d) tympanometric peak pressure; and (e) static-acoustic middle-ear admittance. The middle-ear sample was composed of 82 ears of 54 subjects ranging in age from 3 to 11 years. The control (normal-hearing, normal middle-ear) sample was composed of 53 ears of 53 subjects ranging in age from 3 to 10 years. Each subject was given a complete otolaryngologic evaluation (including pneumotoscopy and/or microtoscopy) and audiologic (including acoustic-immittance) evaluation. In the group of middle ears with normal-hearing sensitivity, the sensitivity and specificity of the ASHA guidelines were 63 percent and 79 percent, respectively. An acoustic-immittance screening protocol, based on all of the individual acoustic-immittance measures, and characterized by high sensitivity and specificity, is proposed.
(a) 鼓室图宽度；(b) 同侧声反射消失；(c) 美国言语语言听力协会（ASHA）指南；(d) 鼓室图峰压；以及 (e) 静态中耳声导纳。中耳样本由54名年龄在3至11岁之间的受试者的82只耳朵组成。对照组（听力正常、中耳正常）样本由53名年龄在3至10岁之间的受试者的53只耳朵组成。对每名受试者进行了全面的耳鼻喉科评估（包括鼓膜镜检查和/或显微镜检查）和听力学（包括声导抗）评估。在听力敏感度正常的中耳组中，ASHA指南的敏感性和特异性分别为63%和79%。本文提出了一种基于所有个体声导抗检测指标的声导抗筛查方案，该方案具有高敏感性和特异性。
