ABSTRACT
BACKGROUND:
Wideband absorbance (WBA) measured at ambient pressure (WBAA) does not directly account for middle ear pressure effects. On the other hand, WBA measured at tympanometric peak pressure (TPP) (WBATPP) may compensate for the middle ear pressure effects. To date, there are no studies that have compared WBAA and WBATPP in ears with surgically confirmed otitis media with effusion (OME).PURPOSE:
The purpose of this study was to compare the predictive accuracy of WBAA and WBATPP in ears with OME. RESEARCHDESIGN:
Prospective cross-sectional study. STUDY SAMPLE A total of 60 ears from 38 healthy children (mean age = 6.5 years, SD = 1.84 years) and 60 ears from 38 children (mean age = 5.5 years, SD = 3.3 years) with confirmed OME during myringotomy were included in this study. DATA COLLECTION ANDANALYSIS:
Results were analyzed using descriptive statistics and analysis of variance. The predictive accuracy of WBAA and WBATPP was determined using receiver operating characteristics (ROC) analyses.RESULTS:
Both WBAA and WBATPP were reduced in ears with OME compared with that in healthy ears. The area under the ROC (AROC) curve was 0.92 for WBAA at 1.5 kHz, whereas that for WBATPP at 1.25 kHz was 0.91. In comparison, the AROC for 226-Hz tympanometry based on the static acoustic admittance (Ytm) measure was 0.93.CONCLUSIONS:
Both WBAA and WBATPP showed high and similar test performance, but neither test performed significantly better than 226-Hz tympanometry for detection of surgically confirmed OME.
