Background/Objectives: Obstructive sleep apnea (OSA) is a prevalent sleep-related breathing disorder characterized by repeated episodes of upper airway obstruction during sleep, leading to intermittent hypoxia and fragmented sleep architecture. Orofacial myofunctional therapy (OMT) has emerged as a promising non-invasive approach to improving airway patency in individuals with mild-to-moderate OSA. However, the role of sleep ergonomics—including sleep posture and pillow support—in enhancing OMT outcomes remains underexplored. This study aimed to evaluate whether ergonomic interventions could augment the therapeutic effects of OMT in adult patients with mild-to-moderate OSA. Methods: A 12-week prospective cohort study was conducted involving 60 adult participants diagnosed with mild-to-moderate OSA. All participants underwent a structured orofacial myofunctional therapy (OMT) program comprising exercises for tongue elevation, lip seal enhancement, and soft palate strengthening. In addition, ergonomic instructions were provided regarding optimal sleeping posture and pillow adjustment. Compliance with ergonomic practices was monitored weekly using infrared night-vision cameras and reviewed by a blinded sleep technician. Pre- and post-intervention assessments included apnea–hypopnea index (AHI), Pittsburgh Sleep Quality Index (PSQI), and Ep-worth Sleepiness Scale (ESS). Results: Statistically significant improvements were observed in all measured parameters following the intervention. AHI scores reduced from 18.2 ± 4.5 to 10.6 ± 3.9 events/hour (p < 0.001), PSQI scores improved from 11.3 ± 2.1 to 6.5 ± 1.8 (p < 0.001), and ESS scores declined from 13.7 ± 2.6 to 7.4 ± 2.0 (p < 0.001). Participants with high adherence to ergonomic recommendations demonstrated significantly greater clinical improvements compared to less adherent individuals. Conclusions: The combination of ergonomic sleep posture interventions with OMT was associated with positive improvements in sleep-related outcomes, comparable to or in some cases better than those reported in previous studies evaluating these interventions independently. As an observational cohort without a control arm, this study cannot establish causality but provides preliminary evidence to guide the design of future randomized clinical trials.

(1) Background/Objectives: Obstructive Sleep Apnea (OSA) in childhood is a significant health concern with potential adverse effects on daytime function, behavior, education, and overall development. Early intervention is crucial to ease these consequences. Myofunctional therapy (MT) has emerged as a treatment modality, particularly in young children, to address OSA. This highlights the importance of early detection and intervention by pediatric dentists and other healthcare providers who frequently interact with the pediatric oral and facial structures. This study aimed to investigate the knowledge, attitudes, and practices of Lebanese pediatric dentists regarding pediatric OSA and MT. (2) Methods: A cross-sectional survey was distributed to 103 Lebanese Pediatric dentists registered with the Lebanese Society of Pediatric Dentistry (LSPD). The survey assessed familiarity with OSA, diagnostic practices, treatment approaches, and utilization of MT. (3) Results: Out of 103 pediatric dentists, 62 responded (60.2%). Most respondents were familiar with OSA (86.8%). However, the number of diagnostic symptoms used varied. MT was not pediatric dentists’ primary choice in treating OSA. (4) Conclusions: Lebanese pediatric dentists demonstrate a good understanding of OSA, but there is potential for improvement in diagnostic comprehensiveness and exploration of MT as a treatment option.

Background: Mouth breathing and obstructive sleep apnea (OSA) in children are interrelated conditions that can negatively impact neurocognitive development and overall quality of life. This study aimed to critically analyze the available evidence regarding the relationship between these conditions, highlighting their prevalence, clinical consequences, and therapeutic approaches. Methods: To this end, an umbrella review was conducted, including systematic reviews and meta-analyses retrieved from scientific databases, following rigorous inclusion criteria. Results: A total of six systematic reviews met the inclusion and exclusion criteria and were included in the final analysis. These studies explored various aspects of the topic and underwent a thorough assessment of methodological quality. Conclusions: The findings indicated that mouth breathing may act as both a predisposing and aggravating factor for OSA, while OSA itself may contribute to the persistence of this breathing pattern. However, the methodological heterogeneity among the included studies posed a challenge to synthesizing the findings, underscoring the need for more standardized research. It is concluded that early interventions and multidisciplinary approaches are essential for the effective management of these conditions. Furthermore, this review provides a foundation for future research in this area.
