Background and Objectives Wideband tympanometry (WBT) provides information additional to what can be provided by the relms of traditional tympanometry, such as absorbance, resonance frequency, peak pressure. We investigated characteristics WBT in various middle ear disorders, especially for chronic otitis media (COM), otosclerosis, patulous eustachian-tube disorder (ETD). Subjects Method recrui...

BACKGROUNDS AND OBJECTIVE The hearing assessment of the newborns ideally should detect both middle and inner ear functions. The aim of this study is to control the association between otoscopic evaluation, multifrequency tympanometry and TEOAE results. METHODS Fifty new-borns otherwise healthy were tested after the otolaryngological evaluation by 226 and 1000 Hz tympanometries and transient e...

This study examined the test performance of distortion product otoacoustic emissions (DPOAEs) when used as a screening tool in the school setting. A total of 1003 children (mean age 6.2 years, SD = 0.4) were tested with pure-tone screening, tympanometry, and DPOAE assessment. Optimal DPOAE test performance was determined in comparison with pure-tone screening results using clinical decision ana...

OBJECTIVE We sought to further examine the relationship between tympanometry and mortality after noting an unexpected association on assessment of baseline data of a study whose primary aim was to investigate the utility of noninvasive tympanic membrane displacement measurement for monitoring intracranial pressure in childhood coma. METHODS We recruited children who presented with acute nontr...

UNLABELLED This study aimed at describing and analyzing tympanometric results obtained with 226 Hz and 1000 Hz probe tones; checking for correlations between tympanometry, otoacoustic emissions and otoscopic examination; describing abnormal results found in the evaluation procedures. METHODS Double-blind and prospective study. Our sample included 70 babies, between 7 days and one month and 13...

BACKGROUND Tympanometry can indicate middle ear effusion in children referred for tympanostomy tube placement. In outpatient setting, objective adjunctive tools are needed to diagnose the otitis media spectrum. METHODS We enrolled and followed 515 children aged 6-35 months at primary care level. We compared tympanometry with pneumatic otoscopy and evaluated the proportions of type A, C1, C2, ...
