The effect of adenoidectomy or adenotonsillectomy on occlusal features in mouth-breathing preschoolers.

Purpose: The purpose of this study was to evaluate mouth-breathing and nasal-breathing children prior to surgical intervention and 28 months postoperatively, comparing the occlusal features obtained pre- and postoperatively through orthodontic study casts.

Methods: The mouth-breathing (MB) group consists of 33 MB children who underwent surgery and presented a nasal-breathing (NB) pattern after surgery. The control group comprised 22 NB children.

Changes in facial morphology after adenotonsillectomy in mouth-breathing children.

Background: Morphological and dentofacial alterations have been attributed to impaired respiratory function.

Objective: To examine the influence of mouth breathing (MB) on children facial morphology before and after adenoidectomy or adenotonsillectomy.

Methods: Thirty-three MB children who restored nasal breathing (NB) after surgery and 22 NB children were evaluated.

Skeletal and occlusal characteristics in mouth-breathing pre-school children.

This study verified the influence of chronic mouth breathing on dentofacial growth and developmental in pre-school children. The study evaluated 73 children, both sexes, ranging from 3 to 6 years of age. After the otorhinolaryngological breathing diagnosis, 44 mouth-breathing children and 29 nasal-breathing children were compared according to facial and occlusal characteristics.

Muscular, functional and orthodontic changes in pre school children with enlarged adenoids and tonsils.

Introduction: Hypertrophy of the adenoids and palatine tonsils is the second most frequent cause of upper respiratory obstruction and, consequently, mouth breathing in children. Prolonged mouth breathing leads to muscular and postural alterations which, in turn, cause dentoskeletal changes.

Objective: The aim of this study was to determine muscular, functional and dentoskeletal alterations in children aged 3-6 years.
