Impact of rapid maxillary expansion on mouth-breathing children and adolescents: A systematic review.

Background: Rapid maxillary expansion (RME) is an orthodontic procedure used to correct transverse maxillary deficiency. Due to the anatomical relationship between the palate and the nasal cavity, RME promotes an increase in nasal dimensions, which should hypothetically improve nasal respiratory function. Objective: This review aimed to systematically verify studies that assessed the effects of RME on nasal patency in mouth-breathing children and adolescents.

Correlation between acoustic rhinometry, computed rhinomanometry and cone-beam computed tomography in mouth breathers with transverse maxillary deficiency.

Introduction: To provide clinical information and diagnosis in mouth breathers with transverse maxillary deficiency with posterior crossbite, numerous exams can be performed; however, the correlation among these exams remains unclear.

Objective: To evaluate the correlation between acoustic rhinometry, computed rhinomanometry, and cone-beam computed tomography in mouth breathers with transverse maxillary deficiency.

Methods: A cross-sectional study was conducted in 30 mouth breathers with transverse maxillary deficiency (7-13 y.
