Postural alterations in children with mouth breathing assessed by computerized biophotogrammetry.

Objectives: To determine and compare the posture of children with obstructive (OMB) and functional mouth breathing (FMB) and children with nasal breathing (NB) using computerized biophotogrammetry, as well as to determine the viability and efficacy of this method.

Methods: Evaluative and personalized methods were used for the capture and analysis of angle images obtained from 19 NB, 26 FMB and 17 OMB children of either gender aged 8 to 10 years on anterior, posterior and profile views. The nonparametric Kruskal-Wallis test was applied to analyze the three groups as a whole and the Mann-Whitney test was used for pairwise comparison of the groups (p = 0.
