Reliability of tympanometric measures obtained with children.
Conductance and susceptance measurements at probe frequencies of 220 and 660 Hz from eleven children's ears at intervals of 1 min, 10 min, 1 day, and 1 week (7 to 10 days) were obtained utilizing the Grason-Stadler Otoadmittance Meter model 1720. All test-retest correlation coefficients were found to be statistically significant (p less than 0.05); therefore, reliability of tympanometric measures using this instrument with children seems to be adequate for clinical use.
