Morphofunctional changes following adenotonsillectomy of obstructive sleep apnea children: a case series analysis.

Objective: To perform a case series analysis of the changes in the pulmonary artery systolic pressure (PASP), nasal inspiratory flow (NIF), upper airway volume, obstructive apnea/hypopnea index (OAHI), and the maxillomandibular three-dimensional (3D) morphology after adenotonsillectomy (T&A) of obstructive sleep apnea children (OSA).

Materials And Methods: Retrospective assessment of files from 1002 children screened between 2012 and 2020 in a hospital-based mouth-breather referral center. From this universe, 15 obstructive sleep apnea children (7 females; 8 males), ages 4.

Pulmonary arterial pressure and nasal obstruction in mouth-breathing children: Similarities between adenotonsillar hypertrophy and allergic rhinitis.

Background: Upper airway obstruction may cause pulmonary hypertension in childhood. In this study we aimed to identify a possible correlation of systolic pulmonary arterial pressure (SPAP), using Doppler echocardiography, with nasal patency (NP), as measured by rhinomanometry, in mouth-breathing (MB) children with allergic rhinitis (AR) and adenotonsillar hypertrophy (ATH).

Methods: In this cross-sectional study we evaluated 183 patients, from 2 to 12 years of age, at an MB referral clinic in Brazil, from December 2013 to 2017.

Impact of adenotonsilectomy on nasal airflow and pulmonary blood pressure in mouth breathing children.

Introduction: Adenotonsillar hyperplasia (ATH) causing upper airway obstruction (UAO) may increase pulmonary artery systolic pressure (PASP). Early diagnosis and mouth breathing (MB) management may help in cases of high PASP. Total inspiratory nasal airflow (TINAF) obtained by active anterior rhinomanometry (AARM) is a means to quantify nasal patency.

Evolution of obstructive sleep apnea syndrome, nasal flow and systolic pressure of the pulmonary artery in children with indication for adenoidectomy and/or tonsillectomy over 18 months.

Background: Obstructive sleep apnea syndrome in childhood has aroused great interest due to its cardiovascular repercussions and its adverse effects on the quality of life of the affected individuals. However, fundamental aspects of the syndrome remain unknown.

Objective: Herein we prospectively assessed pulmonary artery systolic pressure (PASP) and nasal flow in children with obstructive oral breathing with an indication for adenoidectomy and/or tonsillectomy and their relationship to the obstructive apnea and hypopnea index (OAHI).

Base of the skull morphology and Class III malocclusion in patients with unilateral cleft lip and palate.

Objective: The aim of the present study was to determine the morphological differences in the base of the skull of individuals with cleft lip and palate and Class III malocclusion in comparison to control groups with Class I and Class III malocclusion.

Methods: A total of 89 individuals (males and females) aged between 5 and 27 years old (Class I, n = 32; Class III, n = 29; and Class III individuals with unilateral cleft lip and palate, n = 28) attending PUC-MG Dental Center and Cleft Lip/Palate Care Center of Baleia Hospital and PUC-MG (CENTRARE) were selected. Linear and angular measurements of the base of the skull, maxilla and mandible were performed and assessed by a single calibrated examiner by means of cephalometric radiographs.
