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.

Purpose: Ankyloglossia (tongue-tie) can lead to oromyofascial dysfunction which affects breathing, swallowing, speech, and posture. This study presents the evolution and outcomes of a refined lingual frenuloplasty protocol that integrates individualized myofunctional therapy to address compensatory patterns. Methods: A prospective cohort of 445 patients (≥4 years) was treated between 2021 and 2023 using a fascia-preserving CO2 laser protocol with structured pre- and postoperative myofunctional therapy. Patients were stratified as pediatric (<12 years) or adolescent/adult (≥12 years). Key refinements included fascia-sparing dissection, reduced suture tension with cyanoacrylate adhesive, defined functional endpoints, structured myofunctional therapy, and standardized wound-healing strategies. Results: Among 379 patients (85% response) with >2 months follow-up, the 2025 protocol achieved an 86% satisfaction rate and significantly fewer complications compared with 2019 (pain 3.7% vs. 15.8%; bleeding 1% vs. 13%; revision 2.1% vs. 6.6%). Deeper genioglossus dissection increased swelling risk (OR = 4.0, p < 0.0001) but did not affect satisfaction. Conclusions: The refined 2025 protocol represents an outcome-tracked advancement in ankyloglossia management. By emphasizing fascia preservation, functional diagnostics, and integrated myofunctional therapy, the approach improves safety, efficacy, and patient-centered outcomes.

Background: Orofacial myofunctional therapy (OMT) is frequently applied to correct atypical swallowing, yet its therapeutic strategies remain heterogeneous and poorly standardized. Objective: This scoping review aimed to characterize the strategies described in the literature for OMT in individuals diagnosed with atypical swallowing. Methods: Following Joanna Briggs Institute and PRISMA-ScR guidelines, and with a registered protocol, we included clinical and experimental studies without age restriction, conducted in clinical or research contexts. Studies were retrieved from PubMed, EMBASE, and Cochrane Library using MeSH terms and specific keywords. Data were extracted using a standardized form and summarized descriptively. Results: Twelve studies published between 1989 and 2024, involving 164 participants aged 5–26 years, were included. Interventions were mainly performed by speech-language pathologists in pediatric and adolescent populations, combining tongue posture exercises, muscle strengthening, orofacial mobility, and functional swallowing training. Treatment duration ranged from 8 weeks to 6 months, with weekly sessions and home practice recommendations. In 83% of studies, improvements in swallowing patterns and tongue posture were reported, especially when combined with orthodontic treatment. Conclusions: OMT is characterized as a multifactorial intervention integrating muscle training and functional re-education, but variability in protocols and lack of standardization limit clinical comparability. Future multicenter studies with greater methodological control are needed.

Objective: Accurate measurement of orofacial muscle strength is essential for phenotyping patients with obstructive sleep apnea (OSA), and particularly those with hypotonic phenotypes. High costs associated with gold standard devices such as the Iowa Oral Performance Instrument (IOPI®) limit their clinical use. This study aims to validate the Sandway® manometer, a low-cost alternative to the IOPI®, by comparing its performance against the IOPI® and the Tongue Digital Spoon (TDS) in both laboratory and clinical settings. Methods: We conducted a two-phase study. In the laboratory phase, pressure readings from the IOPI® and Sandway® devices were compared using standardized force application methods. In the clinical phase, 60 patients with moderate-to-severe untreated OSA underwent orofacial strength evaluation using IOPI®, Sandway®, and TDS devices. Intraclass Correlation Coefficient (ICC), Bland–Altman analysis, and Pearson correlation were used to assess reliability and agreement. Results: The Sandway® showed excellent reliability for anterior tongue and lip strength measures (ICC = 0.978). Bland–Altman plots revealed minimal bias and narrow limits of agreement compared to the IOPI®, indicating strong agreement for both tongue and lip measurements. A high correlation was also observed between Sandway® and TDS results (r = 0.863, p < 0.001), supporting secondary validation. Conclusions: The Sandway® manometer demonstrates high reliability and strong agreement with gold standard instruments, representing a valid, accessible alternative for objective assessment of orofacial muscle strength in clinical practice.

Background: The aim of this article is to describe the protocol of a large, multicenter randomized controlled trial evaluating the effects of orofacial myofunctional therapy with auto-monitoring (OMTa) versus auto-monitoring alone on obstructive sleep apnea (OSA) assessed by the apnea–hypopnea index and other pre-specified outcomes. Method: The OMTaOSA study protocol was registered at ClinicalTrials.gov (NCT06079073) in August 2023, and data collection ended in January 2025. One hundred and four participants with mild and moderate OSA were included. Randomization was conducted in a 1:1 ratio, using sex-stratified blocks. The intervention was a standardized protocol of OMT exercises previously shown to be effective, auto-monitoring with a Withings scan watch, and feedback from self-reports. Controls received watches and access to the same application without the exercise module. Sleep was measured over three nights at baseline and after three months. The sleep scorer and researchers evaluating other outcomes were blinded to the treatment allocation. Change in the apnea–hypopnea index was defined as the primary outcome. Secondary outcomes are published on Clinicaltrials.gov. Results: The results of the trial are still in preparation. Conclusions: By addressing the limitations of previous OMT studies, this trial may clarify the effectiveness of digitally delivered OMT for patients with mild to moderate OSA.

Background/Objectives: Tongue thrust (TT) occurs when abnormal tongue movements cause anterior tongue placement with pressure and contact against or between the teeth, potentially affecting the oral phase of swallowing, impacting eating, breathing and speaking. There is limited literature on the diagnostic and treatment approaches for TT, as well as involvement of health practitioners in its management. This study aims to examine the current knowledge and practices related to TT diagnosis and treatment among health professionals in Australia. Methods: A two-phase explanatory sequential mixed methods approach was adopted, comprising an online survey that collected participants’ demographic information and details on assessment, diagnosis, management, referral practices, and relevant experience and training. Phase one involved 47 health professionals from various disciplines in Australia who completed an online survey in its entirety. Phase two included in-depth interviews with seven speech-language pathologists (SLPs) to gain further insights into their experiences in managing TT. Survey data were analysed descriptively, and interview data was analysed thematically. Results: Most participants diagnosed TT using clinical assessments, such as general observation and oral motor examinations. Treatment approaches commonly included orofacial myofunctional therapy and the use of myofunctional devices. Interviews with SLPs identified four key themes: tongue thrust as a symptom rather than a diagnosis, facilitators to effective treatment, multidisciplinary approaches to management, and training and education gaps in clinical practice. Conclusions: This study provides valuable insights into how TT is identified, assessed, diagnosed, and managed by health professionals in Australia. It highlights the perspectives of SLPs on treatment approaches, as well as their views on the availability and adequacy of training and education in this field. The findings suggest the need for a broader understanding of TT management, emphasising the importance of multidisciplinary collaboration and professional development. These insights are globally relevant, as they stress the shared challenges and the value of international collaboration in improving TT diagnosis and treatment practices.

Orofacial myofunctional therapy (OMT) for obstructive sleep apnea (OSA) is a promising, new treatment. We aimed to study patients’ experiences and adherence to OMT. Twelve patients with OSA were included in the study, and they engaged in OMT exercises three times daily for 12 weeks. Participants tracked their sleep and OMT exercise activities in an electronic diary. Exercise techniques were guided by a certified therapist. Patients’ experiences with OMT were assessed through semi-structured individual interviews conducted after a 12-week intervention, and the transcripts were analyzed using thematic analysis. The findings revealed an overarching theme that captured both facilitators of and barriers to OMT, organized into three subthemes: (1) motivation, (2) perceived support, and (3) perceived effects. Motivation was driven by a desire to improve general health and avoid continuous positive airway pressure treatment, and was supported by a sense of mastery and perceived effectiveness. Key facilitators included a trusting patient–therapist relationship, as well as developing routines and a sense of control. Barriers involved managing the comprehensive treatment protocol, insecurities around exercise execution and the potential impact of OMT, sickness burden, and previous negative healthcare experiences. These themes were supported by quantitative findings, which demonstrated high treatment adherence, while sleep data indicated modest individual improvements in subjective sleep quality and efficiency. By recognizing facilitators and barriers and addressing the individual differences among OSA patients, healthcare providers can better tailor their approach to meet diverse patient needs. This personalized approach, supported by emerging sleep improvements, may enhance patient engagement and improve adherence to OMT.

Ankyloglossia causes impairment of normal tongue motility and disrupts the average balance of the muscle forces that form the orofacial complex. Inadequate swallowing from birth can cause long-term anatomical and functional consequences in adult life. Using the video presented herein, we describe the current knowledge about the long-term implications of ankyloglossia. After a literature review of the Medline, Google Scholar, and Embase databases on the relations between ankyloglossia and sleep-disordered breathing, we designed and created a three-dimensional (3D) video using Adobe After Effects based on the anatomical and functional changes produced by repeated deglutition, with and without ankyloglossia, from childhood to adulthood. The animated video (Blender 3D, Amsterdam, The Netherlands, 2024) presented herein was based on the most recent literature review of dentition, breathing, posture, and abnormal swallowing, emphasizing the importance of the potential consequences of sleep-disordered breathing. The resulting animated 3D video includes dynamic sequences of a growing child, demonstrating the anatomy and physiology of deglutition with and without ankyloglossia, and its potential consequences for the surrounding structures during growth due to untreated ankyloglossia. This visual instructional video regarding the impacts of ankyloglossia on deglutition/swallowing may help motivate early childhood diagnosis and treatment of ankyloglossia. This instrument addresses the main myofunctional aspects of normal deglutition based on the importance of free tongue motion and can be used by students or professionals training in myofunctional disorders.

Orofacial myofunctional therapy (OMT) is an intervention approach used to remediate orofacial myofunctional disorders (OMDs). OMDs are abnormal patterns involving the oral and orofacial musculature that can subsequently interfere with the normal growth, development, or function of orofacial structures, including speech production. Historically, articulation therapy is used to remediate speech sound disorders (SSDs). Currently, there is a dearth of literature on the use of OMT to treat non-developmental (organic) SSDs in children. The aim of this systematic review is to examine the effectiveness of OMT in treating organic SSDs in children and adolescents between 4 and 18 years of age. A search of five electronic databases (ProQuest, Scopus, Ovid, CINAHL, and Embase) was conducted, including backward (identifying and reviewing references from earlier studies from sources) and forward searching (reviewing newer studies that have cited a source). Only primary research including OMT with post-treatment outcome measures for speech production were included. Thirteen studies were reviewed, including a total of 397 participants between 4 and 17 years of age. A range of study designs, diagnoses, and intervention approaches were discussed. Studies yielded mixed results on the effectiveness of OMT to treat organic SSDs. OMT alone, and in combination with articulation therapy, was not found to be more effective than articulation therapy alone. The methodological quality of the studies ranged from limited to strong. Findings from high quality studies showed no improvement to speech that could be directly attributed to OMT, and lower quality studies yielded mixed results. This review found no conclusive evidence supporting the use of OMT as a standalone treatment for the effective remediation of SSDs. This is attributed to significant variability in speech outcomes, small sample sizes, limited comparison groups, diverse participant diagnoses, and inconsistent methodologies and treatment protocols, yielding mixed results. In addition, while the term OMT was used in the papers to designate treatment methodology, an analysis of the exercise descriptions revealed that some reported OMT exercises were non-speech oral motor exercises (NSOMEs) and oral motor therapies. Overall, many of the techniques utilized across studies did not provide speech-like movements in their therapeutic interventions based on their description. Finally, traditional articulation therapy, including speech drills to work on articulation disorders, was not included in many of the included studies. SLPs using OMT as a modality would typically combine this with articulation practice to treat the SSD. This study highlights the need for robust future studies including prospective cohort studies to compare OMT, combined OMT and articulation therapy, and articulation therapy alone to provide clearer guidance for future clinical practice.

Purpose: Ankyloglossia or tongue-tie (TT) occurs when the lingual frenulum is visually altered and accompanied by restricted tongue mobility causing feeding and other difficulties for infants. Pre- and post-operative stimulation techniques are known to be effective in preventing tissue reattachment and ensuring feeding success. The aim of this study was to gather feedback from parents and health professionals for an experimental evidence-based pre- and post-operative care protocol for breastfeeding infants undergoing surgical management for TT. Methods: A qualitative approach was used to evaluate an experimental pre- and post-operative care protocol for infants with TT, through virtual semi-structured interviews with clinicians and parents of children with TT. Five parents and eight current practicing clinicians were interviewed to obtain feedback on the protocol in development. The results were analyzed using thematic analysis. Results: Four themes were generated from participants: (1) parental confidence and competence, (2) the need for individualized and adaptable instruction; (3) supporting the parent and infant equally; and (4) regular and periodic support and adjustment to protocol. Conclusions: The findings from the qualitative interviews highlighted the importance of fostering parental confidence and education, adaptability and flexibility in care, and clinician reassurance throughout the process. The participants suggested these factors would contribute to greater adherence to care protocols and improved outcomes for both infants and their families. This research emphasizes the importance of providing care that extends beyond logistics of oral stimulation techniques and instead recommends a mindful, family-centered approach that empowers and motivates families throughout the process.

Purpose: The purpose of this systematic review was to systematically explore improvements in gastrointestinal symptoms 1 week and 1 month following the frenotomy procedure, compared to before the procedure for infants under 12 months of age using meta-analysis calculations. Methods: Studies were selected that presented data on breastfed infants under 12 months of age, with gastrointestinal symptoms and reflux, who underwent surgical correction for restricted maxillary labial frenum and/or ankyloglossia, and/or maxillary buccal frena. Case reports, letters to editors, previous systematic reviews, in vitro and animal studies, and only abstracts were excluded. An integrative literature review was carried out in MEDLINE via PubMed, EBSCOhost, Scopus Embase, Web of Science & Cochrane Library from April 2016 to March 2023. Risk of bias was evaluated using the Modified Newcastle‐Ottawa Scale. GRADE profiler (GRADEpro) was used to rate the quality of evidence. We conducted meta-analysis using random effects modelling with the RevMan Software 5.4. Results: Out of the 90 studies identified, nine studies were included, seven were prospective cohort studies, one was a prospective randomized trial, and one was a retrospective analysis. Gastroesophageal reflux symptoms showed statistically significant improvement in I-GERQ-R scores after 1 week (effect size = 3.40, p < 0.00001) and 1 month (effect size = 6.37, p < 0.00001) as compared to before release. Kotlow Class 3 and Class 4 lip tie, Coryllos Type 3 and Type 4 tongue tie showed maximum symptoms and the greatest improvement after release. Conclusion: Tethered oral tissues should be considered as a potential etiology in the differential diagnosis of gastrointestinal reflux in infants.

Objectives: The aims of this study were to (1) evaluate if there were any significant differences in gastrointestinal (GI) and/or feeding symptoms for infants with tethered oral tissues (TOTs) pre-frenotomy compared to infants with untreated TOTs and infants without TOTs, and (2) evaluate if treatment via frenotomy led to improvements in symptoms that more closely align with GI and/or feeding symptoms in infants with untreated TOTs and/or infants without (TOTs). Methods: This study utilized a pretest-only control group design. The Infant Eating Assessment Tool (InfantEAT) and Gastrointestinal and Gastroesophageal Reflux (GIGER) Scale were used to evaluate infant feeding and GI symptoms, respectively. Multiple linear regression was used to compare scores between the three groups at baseline, controlling for age and gestational age at birth. Treatment group’s average score after intervention was compared to the mean baseline score of the other two groups. For the treatment group, paired t-test was used to evaluate changes in scores before and after the treatment. Results: All subscales of both the InfantEAT and GIGER demonstrated statistically significant differences for infants with TOTs before intervention when compared with infants with TOTs who did not undergo treatment and infants without TOTs. Conclusion: This study demonstrates the importance of considering structure along with function for infants with tongue- and/or lip-tie. Clinicians must evaluate maternal symptoms alongside infant factors. The decision to treat TOTs via frenotomy is multifactorial and is not necessary in every mother-infant dyad.
