Acoustic-immittance screening for detection of middle-ear effusion in children.
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.
