Measuring resonance frequency of the middle ear in school-aged children: potential applications for detecting middle ear dysfunction.

WBT-estimated RF had fair diagnostic accuracy for predicting PTS and tympanometry results, but had excellent accuracy for predicting the presence of middle ear dysfunction, indicated by a Type B tympanogram. WBT-estimated RF does not require age-, gender-, ear- or ethnicity-specific normative data for clinical use with children.
