Tympanometry with 226 and 1000 Hertz tone probes in infants.
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...
متن کاملAccoustic immitance measures in infants with 226 and 1000 hz probes : correlation with otoacoustic emissions and otoscopy examination Summary
Audi ological evaluation in infants should include the middle ear (immitance measures and otoscopy) and also a cochlear evaluation. Aim: To check which tympanometry tone test (226 Hz or 1000 Hz), transient otoacoustic emissions and otoscopy. Methods: Transient otoacoustic emissions were taken from sixty infants ranging from zero to four months of age. The babies were assigned to two groups of 3...

متن کاملMultifrequency tympanometry in infants
INTRODUCTION The use of conventional tympanometry is not sufficiently sensitive to detect all cases of middle ear changes, and this hinders accurate diagnosis. OBJECTIVE To characterize acoustic immittance measures of infants from 0 to 3 months of age using multifrequency tympanometry in a prospective study. METHOD 54 infants from 0 to 3 months of age were evaluated. The inclusion criter...
متن کاملNormative multifrequency tympanometry in infants and toddlers.
Multifrequency tympanometry data were measured multiple times between the ages of four weeks and two years from 33 infants/toddlers. Tympanograms were also measured from 33 adult participants. Tympanograms recorded with five probe-tone frequencies (226, 400, 630, 800, and 1000 Hz) were classified using the Vanhuyse et al model classification system (Vanhuyse et al, 1975). Admittance at +200 daP...
