| Popis: | The acoustic reflectometer, a diagnostic tool for detecting middle ear effusion, allows for noninvasive testing that is not affected by cerumen, crying, or client cooperation. This study assessed the predictive accuracy, sensitivity, and specificity of acoustic reflectometry versus tympanometry in the middle ear screenings for 357 children. Results were analyzed according to sex, age, and sensorineural hearing status. Intratest reliability was highly significant and the device was easily used with difficult-to-test clients. While positive predictive accuracy and specificity rates were excellent , sensitivity rates were extremely poor. It was concluded that the acoustic reflectometer is a poor screening device for standard hearing screenings. The lower prevalence of middle ear effusion found in the normal population greatly affected the device's sensitivity or ability to detect diseased ears. The percentage of ears with middle ear effusion that would go undetected undermines the tool's utility for standard school hearing screenings. |
