Changes in vertical dentofacial morphology after adeno-/tonsillectomy during deciduous and mixed dentitions mouth breathing children--1 year follow-up study.

Objective: The aim of this 1 year follow-up study was to investigate, in mouth breathing children, the impact of respiration normalization on vertical dentofacial growth during two stages of dental development after adeno-/tonsillectomy.

Method: Linear and angular cephalometric measurements, as well as tracing superimposition of serial lateral cephalograms of 39 patients in the treatment group were compared with those of 31 untreated mouth breathing controls. Cephalometric records in the treatment group comprised registrations made at baseline before surgery (T(0)), and then at approximately 1 year post-operatively (T(1)).

Prevalence of malocclusion among mouth breathing children: do expectations meet reality?

Objective: The aim of this study was to report epidemiological data on the prevalence of malocclusion among a group of children, consecutively admitted at a referral mouth breathing otorhinolaryngological (ENT) center. We assessed the association between the severity of the obstruction by adenoids/tonsils hyperplasia or the presence of allergic rhinitis and the prevalence of class II malocclusion, anterior open bite and posterior crossbite.

Methods: Cross-sectional, descriptive study, carried out at an Outpatient Clinic for Mouth-Breathers.
