Introduction This consensus aimed to develop a structured document presenting the role of sleep-focused Speech-Language-Hearing (SPH) Sciences (SPHS). 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. Methods A Delphi method was conducted with 49 SLH pathologists (SLHP), four sleep physicians, one dentist, one physical therapist, and one methodologist. Four Delphi panel rounds were conducted in Google Forms. The items were analyzed based on the panelists' percentage of agreement; consensuses were reached when ⅔ (66.6%) of valid responses were on a same on a same answer (either “agree” or “disagree”). Results Participants voted on 102 items. The mean consensus rate was 89.9% ± 10.9%. The essential topics were the importance of professional training, the SLH diagnosis, and the SLH treatment of sleep disorders. It was verified that all fields of the SLHS are related to the area of sleep; that sleep-focused SLH pathologists (SLHP) are the responsible for assessing, indicating, and conducting specific orofacial myofunctional therapy for sleep-disordered breathing alone or in combination with other treatments; that SLHP are included in interdisciplinary teams in the area of sleep in public and private services. Discussion The Brazilian consensus on sleep-focused SLHS is a landmark in this area. This consensus described the scope of action of sleep-focused SLHP and systematized recommendations being useful as a reference for the professional practice in the area of sleep.

ABSTRACT Introduction: Previous diagnosis and intervention in patients with sleep-disordered breathing involves several health professionals. Speech-Language and Hearing Sciences (SLHS) performance has been solidified through scientific production. Objective: To describe the inclusion of Brazilian Speech-Language Pathologists (SLP) in the field of sleep disorders, through the description of studies, scientific publications and participation in scientific events. Data Synthesis: A search and an analysis of the Brazilian SLP publications in the field of sleep disorders were carried out, including articles, monographs, dissertations, thesis and abstracts published in annals of events. The databases Lilacs, SciELO, Pubmed, Google Scholar tool and Lattes platform were accessed, with final search in January 2018. The analysis consisted of a description of the year of publication, type of publication, area of the SLHS, place of publication and/or event. 40 articles were found in national and international journals, from 1999 to 2017. In relation to publications in books, one book about the subject was published in 2009 and eight chapters of books were published. In the monograph format, 21 studies were carried out, there are 13 dissertations and eight thesis. A total of 151 abstracts were published in annals of scientific events, from 2001 to 2017 and 63 lectures were conducted by SLP. Conclusion: The inclusion of Brazilian SLP in the area of sleep disorders has been supported by scientific publications in the format of articles in national and international journals, monographs, thesis, dissertations, books and publications in event annals. Keywords: Speech; Language; Hearing; Sleep Disorders, Intrinsic; Sleep Apnea, Obstructive.

Orofacial myofunctional therapy has been shown to be effective in the multidisciplinary management of obstructive sleep apnoea syndrome in children, adolescents, and adults, and is prescribed at several stages of such management. However, given the lack of consistency in treatment protocols and outcome measures, the lack of research on the type, frequency and duration of myo-functional exercise and the specific phenotypes that may benefit from it, there is a need to define best practice guidelines. A Delphi consensus guideline on orofacial myofunctio-nal assessment and treatment for patients with OSA was initiated by Marc Richard Moeller. The first two stages of the Delphi consensus recommendations have been completed. The third stage, the development of the questionnaire , will take place at the joint meeting of the World Sleep Society and the Academy of Applied Myofunctional Sciences in March 2022 in Rome. The conclusions of the Delphi consensus recommendations will be published in the following year and widely disseminated.
