ABSTRACT

Objective: To evaluate the reproducibility of acoustic pharyngometries performed in the pediatric population.
Materials and Methods: Analytical, observational, longitudinal prospective study. Children from 3 to 14 years were evaluated with Eccovision Acoustic Pharyngometer, with guidelines based in previously published works. Three readings with oral maneuver and three readings with nasal maneuver were registered per visit, with the first visit at recruitment, the second two to three hours later and the third a week later. ANOVA, intraclass correlation coefficient (ICC) and coefficient of variation were used for analysis.
Results: There were included 24 children, 7.9 ± 3.3 years old, that performed the nasal maneuver and 14 oral maneuver. Intraclass correlation coefficient in the oral maneuver for all measures spanned from 0.75 to 0.94, all ANOVA analysis did not show statistically significant differences between measures across time, and the coefficient of variation encompassed from 0.09 to 0.17 for all three measures.
Conclusions: Acoustic pharyngometry, performed with standard procedures, produces reproducible results in children.
