Purpose: This article presents a narrative review of current recommendations for the clinical evaluation and management of adult patients with obstructive sleep apnea (OSA) to identify points missing from a myofunctional perspective.

Methods: The authors reviewed current official guidelines for adult patients with OSA, searching clinical evaluation and treatment recommendations for myofunctional therapy.

Results: None of the current guidelines for evaluation of adult OSA recommend performing a myofunctional evaluation. Only two guidelines consider myofunctional therapy (MFT) as a treatment modality for adult patients with OSA.

Conclusion: Despite the role of the pharyngeal dilator muscles as an essential contributor to the pathogenesis of OSA, this review has shown that myofunctional assessment is still not a standard recommendation in current guidelines for adult OSA. Recent guidelines occasionally include MFT as a therapeutic tool for OSA. To strengthen the knowledge base and evidence for including MFT treatment for adult patients with OSA, the authors encourage physicians to incorporate myofunctional evaluation into their regular clinical practice.
