A Study of the Facial Soft Tissue Morphology in Nasal- and Mouth-Breathing Patients

Abstract

In participants with skeletal Class II pattern, MB children compared with NB children showed different facial morphology in the same sex group. The children with MB showed a more protruded upper lip and increased lower facial height, accounting for a larger proportion of the facial height. However, no significant correlation was found between facial morphology and breathing pattern. Only correlative trends were found.
