The recommendations were based on the expertise of specialists and on evidence in the literature, aiming to guide the coverage of this area and the consequent improvement in the quality of the professionals' approach.  A Delphi method was conducted with 49 SLH pathologists (SLHP), four sleep physicians, one dentist, one physical therapist, and one methodologist.

Rapid maxillary expansion in pediatric patients with obstructive sleep apnea: an umbrella review.

Objective: To compare polysomnographic parameters with others from the literature in order to provide more accurate information about Rapid Maxillary Expansion (RME) for treating Obstructive Sleep Apnea (OSA) in children, through raising the question: Is RME a good option for treating OSA in children? Prevention of mouth breathing during children's growth remains a challenge with significant clinical consequences. In addition, OSA induces anatomofunctional changes during the critical period of craniofacial growth and development.

Methods: The Medline, PubMed, EMBASE, CINAHL, Web of Science, SciELO and Scopus electronic databases were searched up to February 2021 for systematic reviews with meta-analysis in the English language.

Effectiveness of a Uniquely Designed Oral Appliance on Obstructive Sleep Apnea Control: A Pilot Study.

Objectives:  Obstructive sleep apnea is an inflammatory, chronic, and evolutive disease often needing adequate treatment and follow-up. The oral appliance (OA) is an accepted alternative therapy for obstructive sleep apnea (OSA) control. Due to greater adherence, OA with mandibular advancement (OA) is being recommended treatment for patients who refuse or do not tolerate continuous positive airway pressure.

Is ankyloglossia associated with obstructive sleep apnea?

Objectives: To investigate the evidence on the association between ankyloglossia and obstructive sleep apnea.

Methods: An integrative literature review was carried out in the databases. Observational and interventional studies that assessed the lingual frenulum in children with sleep-disordered breathing were included.

Home sleep apnea testing: an accuracy study.

Aim: There are no studies comparing tests performed at home with those carried out in the laboratory, using the same device. The only studies that have been performed have compared the device used at home with the standard polygraph used in the laboratory. The purpose of this study was therefore to verify the accuracy of the home diagnosis of obstructive sleep apnea syndrome (OSAS) via unassisted type 2 portable polysomnography, compared with polysomnography using the same equipment in a sleep laboratory.

Quality of sleep, health and well-being in a population-based study.

Objective: To estimate the prevalence of poor self-rated sleep and to identify the population subgroups most susceptible to the problem.

Methods: This is a cross-sectional, population-based study developed with data from the Health Survey conducted in the city of Campinas (ISACamp 2014/2015). Data from a sample of 1,998 individuals aged 20 years or older were analyzed.

Cultural adaptation and evaluation of the measurement properties of the Berlin Questionnaire for Brazil.

Objective: to produce the Brazilian version of the Berlin Questionnaire (BQ) with evidence of reliability and validity.

Method: The cultural adaptation was carried out in the following stages: translation, synthesis of translations, back-translation, evaluation by an expert committee and pre-test with 30 participants. Next, the psychometric properties were evaluated with 104 participants who answered the Brazilian version of the BQ and underwent polysomnography (PSG).

Napping, functional capacity and satisfaction with life in older adults: A population-based study.

Aim And Objective: To analyse the association between napping, functional capacity and satisfaction with life in older adult residing in the community.

Method: A cross-sectional population-based study using data from a health survey conducted in a city of the state of São Paulo. Information on sociodemographic and clinical variables was collected through a questionnaire, as well as the occurrence or not of napping and satisfaction with life.

Objective: To correlate cephalometric data with the apnea-hypopnea sleep index.

Obstructive sleep apnea prevents the expected difference in craniofacial growth of boys and girls.

Objectives: It was to compare cephalometric measures of mouth-breather boys and girls and with the cephalometric pattern observed in obstructive sleep apnea syndrome (OSAS) patients.

Methods: Craniofacial measurements of lateral cephalometric radiographs obtained from 144 children aged 7-14 years were compared between boys and girls, and both were compared to cephalometric pattern of OSAS patients.

Results: Mouth-breather boys and girls had no gender differences regarding to craniofacial morphology while nose-breather boys and girls showed those expected differences.

Swallowing dysfunction related to obstructive sleep apnea: a nasal fibroscopy pilot study.

Purpose: Patients with obstructive sleep apnea (OSA) may have subclinical swallowing abnormalities due to progressive mechanical trauma of the pharyngeal tissues caused by snoring. There are few trials on swallowing among OSA patients, and most of them used videoradiography. The aim of this trial was to show swallowing function in OSA patients by nasal fibroscopy.

Polysomnographic findings are associated with cephalometric measurements in mouth-breathing children.

Objectives: Children with adenotonsillar hypertrophy and those with an abnormal craniofacial morphology are predisposed to having sleep disordered breathing; many of these children are mouth breathers. The aim of this study was to determine whether an association exists between polysomnographic findings and cephalometric measures in mouth-breathing children.

Methods: Twenty-seven children (15 mouth-breathing children and 12 nose-breathing children [control subjects]), aged 7 to 14 years, took part in the study.
