Effect of Bimaxillary Orthognathic Surgery on Pharyngeal Airway Volume

Int. j. morphol; 41 (5), 2023
SUMMARY: Subjects with maxillary skeletal classes II and III not only express alterations in the hard and soft maxillofacial tissues, but also in the morphology and dimensions of the upper airway. A small space in the upper airway has been associated with sleep disorders, such as snoring and mainly obstr...

Three-dimensional pharyngeal airway space changes after bimaxillary advancement

ABSTRACT Introduction: The probability of improvement in the upper airway space (UAS) with orthognathic surgery should be considered during the surgical-orthodontic treatment decision, providing not only an esthetic, but also a functional benefit for the patient. Objective: The purpose of this study wa...

Nova análise das vias aéreas superiores através de radiografias Panorâmicas: correlacionando seus locais de estreitamento, fluxo respiratório e de dor Orofacial

A pesquisa teve como objetivo avaliar se radiografias panorâmicas de boca fechada podem ser usadas para observação dos tecidos moles e resistência do fluxo aéreo nas vias aéreas (VA), principalmente da faringe (naso, velo, oro e hipofaringe). Para averiguação do potencial obstrutivo das vias aér...

Avaliação do volume das vias aéreas superiores conforme o padrão facial

RFO UPF; 25 (1), 2020
Objetivo: analisar o volume da via aérea superior (VAS) em pacientes adultos saudáveis, a partir de exames de tomografia computadorizada de feixe cônico, comparando os padrões faciais esqueléticos I, II e III, considerando a idade e o sexo. Método: um estudo retrospectivo de análise do banco de da...

3-D airway analysis related to facial morphology

Int. j. morphol; 38 (2), 2020
The aim of this investigation was to define the volume and area of the airway in subjects with Class II and Class III skeletal deformity. A cross-sectional study was designed including subjects with facial deformity defined by Steiner's analysis in subjects with indication of orthognathic surgery who pre...

State-dependent changes in the upper airway assessed by multidetector CT in healthy individuals and during obstructive events in patients with sleep apnea

J. bras. pneumol; 45 (4), 2019
ABSTRACT Objective: To determine whether airway narrowing during obstructive events occurs predominantly at the retropalatal level and results from dynamic changes in the lateral pharyngeal walls and in tongue position. Methods: We evaluated 11 patients with severe obstructive sleep apnea (OSA) and 7 h...

Volumetric reconstruction and determination of minimum crosssectional area of the pharynx in patients with cleft lip and palate: comparison between two different softwares

J. appl. oral sci; 26 (), 2018
Abstract Objective: The aim of this study was to assess the accuracy of volumetric reconstruction of the pharynx by comparing the volume and minimum crosssectional area (mCSA) determined with open-source applications (ITK-Snap, www.itksnap.org ; SlicerCMF) and commercial software (Dolphin3D, 11.8, Dolph...

Cone-beam computed tomography evaluation of upper airway, dental arches dimensions and buccolingual inclination through of cases treated with Damon system

Introduction: The aim of this study was to assess changes in upper airway, dental arches dimensions and buccolingual inclinations of teeth in patients treated orthodontically with the Damon system. Material and Methods: Twenty-one patients of both sexes, mean initial age of 14.99 ± 1.97 years, with comp...

Videofluoroscopic evaluation of swallows in anorexia nervosa

Arq. gastroenterol; 53 (3), 2016
ABSTRACT Background There are some studies in the literature about the feeding behavior and masticatory process in patients with feeding disorders; however, it is not very well known if there are alterations in oral-pharyngeal swallowing dynamics in subjects with anorexia nervosa. Objective To evaluate...

Evaluation of morphological changes in pharynx with dynamic CT and MRI in snoring patients

Rev. méd. Chile; 144 (9), 2016
Background: Identifying the craniofacial abnormalities that cause snoring and the narrowest area of the upper airway creating obstructions can help to determine the proper method of treatment. Aim: To identify the factors that can cause snoring and the areas of the airway that are the most likely to coll...
