Tongues Tied by Orofacial Myofunctional Therapy about Tongue Tie: A Narrative Review.

Aim and Background: The respective review articles aim is to provide an overview as well as describes and enlists different orofacial myofunctional therapy exercises as a modality for tongue tie secondary to surgery.Tongue tie is the basically a connection that joints base of tongue to the floor of mouth. This leads to difficulties various difficulties such as altered speech, oral habits, maligned teeth and many more. During formative years, most children successfully treated of tongue tie by releasing it, but problems start after its correction. That it may can reappear or may lead to same difficulties as prior. Parents and clinicians are only concerned about speech and aesthetics after release of tongue tie. But OMT plays important role ore and post-surgical procedure. OMT help in proper tongue posture along with reducing the probability of tissue reattachment after surgery by exercises. This therapy positively influenced functions by reducing deleterious habits. Methods: A review of relevant literature is predicated on articles found using free text terms, mesh terms, and some basic tongue tie as well as tongue tie release pamphlets that were published in English up until the year 2023 in the electronic databases PubMed, EBSCO, Scopus, Google Scholar, and Web of Science. With the aid of mesh keywords, the initial search yielded 38-40 articles; 20-35 were chosen depending on the requirements. Also we searched for orofacial myofunctional exercises or exercises recommended after tongue tie release. Results: Various exercises enlisted in our article that will guide a individual before and after tongue tie release which will give positive outcomes such as proper tongue posture, speech, swallow, regained aesthetics and self-esteem. Conclusion: Tongue plays an important role in development of perioral structures as well as in the swallow to good speech articulation and dental occlusion. So, as pediatric dentist its important know that after release of tongue tie what to do and how to maintain. This review article is focused on the various orofacial myofunctional therapy techniques employed for tongue tie but not a single one to describe them. Clinical significance: Our pertaining review act as a guide for clinicians as well as individuals to manage tongue tie after its release.

DISE with CPAP: a useful procedure to evaluate upper airway collapsibility.

PURPOSE: Drug-induced sleep endoscopy (DISE) is commonly performed in patients suffering obstructive sleep apnea (OSA) with continuous positive airway pressure (CPAP) intolerance. We aimed to evaluate the effects of adding CPAP to DISE to provide understanding of the reason of its failure and better guidance in future therapeutic decisions. METHODS: A retrospective observational descriptive study was conducted on CPAP-intolerant patients with moderate-severe OSA. DISE was used to evaluate upper airway collapsibility, and CPAP was tested to better describe anatomical sites of obstruction and to measure the opening pharyngeal pressure. RESULTS: Sample size consisted of 38 patients with a mean age of 49 ± 9 years. Mean BMI was 28.4 ± 2.4 kg/m2, mean apnea-hypopnea index (AHI) was 35.4 events per hour ± 20.1, and mean saturation under 90% (TSat90) was 14.5%. In DISE we found a collapse at Velum in 92% of patients, at Oropharyngeal level in 89%, at tongue in 42%, and at epiglottis in 36%. In the subgroup of patients with clinical failure with CPAP, we observed 100% of epiglottic collapse and 50% of tongue obstruction. In this specific population, we recommended personalized surgery and myofunctional therapy. CONCLUSION: DISE-CPAP is a useful tool to select the treatment that better fits to each patient taking care all information available. It improves our ability to prescribe a multilevel treatment with an exhaustive topographic evaluation of upper airway collapsibility that complements CPAP classic titration, and it can be helpful to distinguish better candidates for surgery, myofunctional therapy or CPAP.

Alternative Therapies for Ankyloglossia-Associated Breastfeeding Challenges: A Systematic Review.

Background: Ankyloglossia (AG) diagnoses are increasingly common, and management is not standardized. Nonsurgical alternative therapies are frequently recommended in conjunction with or instead of frenotomy, with uncertain evidence. Objective: To evaluate the efficacy of nonsurgical alternative therapies (chiropractic care, myofunctional therapy, and osteopathy) in improving breastfeeding for infants diagnosed with AG. Methods: PubMed, Embase, CINAHL, Scopus, Web of Science, Clinicaltrials.gov, and Google Scholar were searched (September-October 2023). Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. A librarian-designed search included the terms "Ankyloglossia," "Non-surgical," "myofunctional therapy," "chiropractic," "osteopathy," and related therapies, with no date restrictions. English language studies of infants <24 months with AG and alternative therapy were included. Risk-of-bias evaluation used Newcastle-Ottawa Scale (NOS). Results: Of 1,304 identified articles, four studies (2016-2022) met inclusion criteria (two cross-sectional, one case report, and one case series). All studies reported frenotomy in combination with alternative therapy yielded favorable outcomes for maternal pain, weight gain, feeding duration, and maintenance of latch. The risk of bias was moderate for two studies, low for the case series, and not calculated for the case report, which has an inherent high risk of bias. All studies lacked control or comparator groups preventing definitive conclusions about the role of alternative therapies in AG. Conclusion: Although some studies suggest the potential benefits of combining alternative therapies with surgery for AG-related breastfeeding issues, the lack of control groups renders the evidence inconclusive. Nonsurgical approaches alone currently lack sufficient evidence. As these alternative therapies gain popularity, rigorous research is crucial to determine their cost-effectiveness and role in managing AG.

Efficacy of the combination of myofunctional therapy (lip exercises) and activator high-pull headgear in the closure of interlabial gap in long-face skeletal class II patients with lip incompetence: A 6-8-month longitudinal randomized clinical trial.

Background: Lip incompetence is an important issue in orthodontics. No study has evaluated the effects of the combination of headgear + lip exercises on lip incompetence. Therefore, this study was conducted. Materials and Methods: This was a longitudinal randomized clinical trial on 29 subjects (16 controls and 13 experimental subjects). Both groups were treated with standardized activator high-pull headgear (and followed up monthly) for 6-8 months. In the experimental group, patients were also instructed to practice certain lip exercises 3 sessions a day, 5 times per session. Pre-/post-treatment interlabial gap, upper lip length and vermilion height, lower lip length and vermilion height, nasolabial angle, and profile convexity angle were measured clinically and photographically, immediately before treatment and after it. Data were analyzed using paired/unpaired t-tests (α = 0.025) and partial correlation coefficient controlling for the intervention type (α = 0.05). Results: Lip exercise plus activator headgear significantly changed/improved all parameters (P ≤ 0.006) over the 6-8-month course of treatment. Activator headgear alone changed/improved only 4 parameters: interlabial gap, upper and lower lip lengths, the lower lip vermilion height, and profile convexity (P ≤ 0.008). Compared to the control (activator headgear alone), in the experimental group, the changes observed in the interlabial gap closure (P = 0.011), upper lip lengthening (P = 0.002), and upper lip vermilion lengthening (P = 0.017) were significantly greater. Convexity angle corrections were more successful in cooperative patients (R = 0.469, P = 0.012). Cases with smaller pretreatment nasolabial angles may experience more changes in this angle after treatment (R = 0.581, P = 0.001). Conclusion: The addition of lip exercises to activator high-pull headgear can boost activator headgear's efficacy in treating lip incompetence.

Use of Ultrasound to Verify the Impact of Telemedicine Myofunctional Therapy on Sleep Apnea Syndrome: Study Protocol Proposal.

The anatomy of the upper airways influences the risk of obstructive sleep apnea (OSA). The size of soft tissue structures, such as the tongue, soft palate, and lateral walls of the pharynx, contributes to the pathogenesis of OSA. New lines of treatment for sleep apnea, such as myofunctional therapy (MT), aim to strengthen the oropharyngeal musculature to improve the defining parameters of apnea. The present protocol uses ultrasound imaging to measure the size of the lingual musculature non-invasively and cost-effectively and evaluates the changes in its morphology. Eligible patients include those with OSA who have undergone submental cervical ultrasound and drug-induced sleep endoscopy before starting MT with the AirwayGym app. Follow-up evaluations are conducted at 3 months after beginning treatment. Patients diagnosed with OSA via questionnaires and polysomnography or respiratory polygraphy are evaluated anatomically and functionally using the Iowa Oral Performance Instrument, a tongue digital spoon, somnoscopy, and submental cervical ultrasound to assess their responses to the AirwayGym app. The lingual thickness (mm) and volume (cm3) and the distance between both lingual arteries (mm) are measured. The AirwayGym app helps users and therapists monitor the patient performance of MT. Incorporating submental ultrasound can be a useful non-invasive tool to evaluate OSA and MT.

Assessment and rehabilitation of tongue motor skills with myofunctional therapy in obstructive sleep apnea: a systematic review and meta-analysis.

STUDY OBJECTIVES: The first objective was to compare tongue motor skills between patients with obstructive sleep apnea (OSA) and healthy subjects. Secondly, the effect of oropharyngeal myofunctional therapy (MFT) on the tongue muscular qualities of patients with OSA was evaluated. METHODS: Searches were conducted in five electronic databases until July 2023. Risk of bias was assessed via the Joanna Briggs Institute appraisal checklist for cross-sectional studies (aim #1) and the PEDro scale for randomized controlled trials (aim #2). Pooled standardized mean differences (SMD) and 95% confidence intervals were calculated using a random-effects model. RESULTS: Thirteen studies including 520 adults and one study including 92 children addressed aim #1. Compared to healthy adults, individuals with OSA had no significant difference in tongue protrusion strength (9 studies, n=366, SMD [95%CI]; -0.00 [-0.45, 0.44]) or endurance (5 studies, n=125; 0.31 [-0.26, 0.88]) but presented a lower tongue elevation strength (6 studies, n=243; 1.00 [0.47, 1.53]) and elevation endurance (3 studies, n=98; 0.52 [0.11, 0.94]). In pediatric, tongue elevation strength was lower but elevation endurance was higher in children with OSA than healthy children. Two randomized controlled trials (28 adults, 54 children) addressed aim #2 and were of poor methodological quality. In these studies, MFT improved tongue motor skills in patients with OSA. CONCLUSIONS: Tongue elevation motor skills are decreased in adults with OSA whereas tongue protrusion motor skills seem preserved. Very few data are available in children. There is also too little data about the impact of myofunctional therapy on tongue motor skills. SYSTEMATIC REVIEW REGISTRATION: Prospero registration number: CRD42022307148.

Use of Edibles as Effective Tools in Myofunctional Therapy: A Pilot Study.

AIM: The aim of this retrospective study is to explore the introduction of edible spread cream and small candies as tools to improve motivation and compliance in young children undergoing myofunctional therapy, with the purpose of optimizing oral functions, including swallowing. METHODS: Six patients, one female and five males, between the ages of 7 and 14 years, presenting with atypical swallowing, were evaluated and treated at the clinic of the University of L'Aquila. The patients included in the study were randomly divided into two groups and were treated with two different treatment protocols: Group A: traditional myofunctional therapy and traditional tools; Group B: same exercises as group A, but with edible tools (spreadable cream and small candies). RESULTS: As expected, the two patients who used edible tools demonstrated increased motivation and collaboration during myofunctional therapy. CONCLUSIONS: Patient compliance, especially in very young patients, limits the effectiveness of myofunctional therapy; therefore, creative solutions are needed to achieve greater cooperation, and edible tools can play a significant part in retraining correct swallowing. Although the sample of this pilot study is small, the results suggest that using actual edible tools in myofunctional therapy could increase compliance and provide better results in myofunctional therapy.

Orofacial Myofunctional Therapy for Obstructive Sleep Apnea: A Systematic Review and Meta-Analysis.

OBJECTIVE: Orofacial myofunctional therapy (OMT) is an alternative form of treatment of obstructive sleep apnea (OSA), that incorporates various exercises to optimize tongue placement and increase oropharyngeal tone. The objective of this systematic review and meta-analysis is to determine the efficacy of OMT in OSA patients. DATA SOURCES: PubMed/Medline, EMBASE, Cochrane, Web of Science. REVIEW METHODS: Using PRISMA guidelines, a directed search strategy was performed for randomized control trials (RCTs) published prior to March 24, 2023, featuring 10+ patients with OSA undergoing mono-therapeutic OMT. The primary outcome of interest was apnea-hypopnea index (AHI). Secondary outcomes included subjective sleepiness, sleep-related quality-of-life, and snoring frequency. RESULTS: Of the 1244 abstracts that were identified, 7 RCTs involving 310 patients met inclusion criteria. Adult OMT patients had a statistically significant improvement in AHI (MD -10.2; 95% CI, -15.6, -4.8, p < 0.05), subjective sleepiness (Epworth Sleepiness Scale; MD -5.66; 95% CI, -6.82, -4.5, p < 0.05), sleep-related quality-of-life (Pittsburgh Sleep Quality Index; MD -3.00; 95% CI, -4.52, -1.49, p < 0.05), and minimum oxygen saturation (MD 2.71; 95% CI, 0.23, 5.18, p < 0.05) when compared with sham OMT or no therapy. Within the single RCT featuring pediatric OMT patients, patients had poor compliance (<50%) and did not show any improvements in AHI, minimum oxygen saturation, or snoring frequency. CONCLUSION: OMT may provide a reasonable alternative for OSA patients who cannot tolerate CPAP or other more established treatment options. OMT benefits appear limited in children due to poor compliance. More studies are required to evaluate compliance and the long-term effects of OMT on OSA outcomes. LEVEL OF EVIDENCE: 1 Laryngoscope, 134:480-495, 2024.

Effect of comprehensive rehabilitation on apnea hypopnea index in patients with obstructive sleep apnea: a protocol for randomized controlled trial.

PURPOSE: The aim of this study is to investigate the effect of comprehensive rehabilitation on apnea hypopnea index (AHI) in patients with obstructive sleep apnea (OSA). METHODS: Patients diagnosed with OSA and meeting the eligibility criteria will be randomly allocated in the groups. The experimental group will receive comprehensive rehabilitation, and the control group will receive myofunctional therapy. CPAP will be continued by all the participants. Both the groups will receive the interventions for 12 weeks. The primary outcome measures are AHI and Epworth Sleepiness Scale (ESS), and secondary outcomes are Pittsburg Sleep Quality Index (PSQI), Oxygen Desaturation Index (ODI), Snoring Index (SI), Manual Assessment of Respiratory Motion (MARM), Breath Hold Test (BHT), and Self Evaluation of Breathing Questionnaire (SEBQ). The outcomes will be assessed at baseline and at the end of 12 weeks. A follow-up will be taken at the end of 24 weeks. Power analysis suggests that enrollment of 118 patients will required. Repeated measures ANOVA will be used to analyze the effect of the intervention. CONCLUSION: By performing this research, we may develop insights on a novel comprehensive approach for treatment of patients with OSA. TRIAL REGISTRATION: CTRI/2023/10/058486.

Salivary biomarker C-reactive protein levels in children with sleep problems and Class II malocclusion before and after twin-block therapy.

Context: Disturbances in sleep affects the overall quality of a child's life, with several short- and long-lasting consequences. Hence, early diagnosis and monitoring is crucial in the management of sleep disorders in children. Aims: The aim of this study was to evaluate salivary C-reactive protein (CRP) levels in a group of children with Class II malocclusion and sleep problems before and after twin-block appliance therapy. Settings and Design: The study was a prospective clinical study with a 9-month follow-up period. Subjects and Methods: Eleven children aged 8-12 years with skeletal Class II malocclusion and at least one sleep disorder were enrolled in the study. All children were subjected to a recording of their sleep history and a clinical as well as radiographic examination. Pretreatment levels of salivary CRP were recorded. A twin-block appliance was custom made and delivered to every child. At the end of 9-month follow-up, all children were recalled for a re-evaluation of salivary biomarker levels. Statistical Analysis: Pretreatment and posttreatment changes in biomarker levels were assessed statistically using the students paired t-test. Results: Levels of salivary biomarker CRP were significantly decreased in children following myofunctional therapy using a twin-block appliance (P < 0.001). There was a considerable improvement in the clinical symptoms such as a decrease in snoring and noisy breathing in most children post-twin-block therapy. Conclusion: The measurement of salivary biomarker CRP could be used as an alternative and noninvasive method to evaluate prognosis of oral myofunctional therapy for children with sleep disordered breathing.

A Multidisciplinary Approach to Swallowing Rehabilitation in Patients with Forward Head Posture.

(1) Background and Objectives: The forward head posture (FHP) is characterized by increased extensions of upper cervical vertebrae and flexion of the lower cervical vertebrae and upper thoracic regions, associated with muscle shortening. The compressive loading on the tissues in the cervical spine negatively impacts suprahyoid and infrahyoid muscles and generates increased tension of the masticatory muscles. The tongue has relations with the suprahyoid and the infrahyoid muscles. The pattern of swallowing evolves gradually from birth to the age of four. If this developmental transition does not occur, the result is persistent infantile or atypical swallowing-an orofacial myofunctional disorder with the tongue in improper position during swallowing, causing strain and stress on the jaw, face, head and neck. In FHP, muscles crucial to swallowing are biomechanically misaligned. The lengthening of the suprahyoid muscles necessitates stronger contractions to achieve proper hyolaryngeal movement during swallowing. This study assesses the added benefits of physiotherapy to the traditional myofunctional swallowing rehabilitation for patients with FHP. The underlying hypothesis is that without addressing FHP, swallowing rehabilitation remains challenged and potentially incomplete. (2) Materials and Methods: A total of 61 participants (12-26 years) meeting the inclusion criteria (FHP and atypical swallowing) were divided into two similar groups. Group A attended one orofacial myofunctional therapy (OMT) and one physiotherapy session per week, group B only one OMT session per week, for 20 weeks. Exclusion criteria were as follows: ankyloglossia, neurological impairment affecting tongue and swallowing, cervical osteoarticular pathology, other previous or ongoing treatments for FHP and atypical swallowing. (3) Results: There is a significant improvement in terms of movement and use of the orofacial structures (tongue, lips, cheeks), as well as in breathing and swallowing in both groups. Group A achieved better outcomes as the CVA angle was directly addressed by manual therapy and GPR techniques. (4) Conclusions: The combined therapy proved to be more effective than single OMT therapy.

An Update on Obstructive Sleep Apnea Syndrome-A Literature Review.

Obstructive sleep apnea syndrome (OSAS) is the most common breathing-related sleep disorder. It is characterized by recurrent episodes of partial or complete airway obstruction during sleep, resulting in a reduction in or the total cessation of airflow, despite ongoing respiratory efforts, leading to oxygen desaturation and arousal. The purpose of this literature review is to evaluate the most common characteristics of this pathology, as well as to investigate the most effective treatment options, providing an update on the management of OSA patients.

The Effects of the Myobrace® System on Peripheral Blood Oxygen Saturation (SpO2) in Patients with Mixed Dentition with Oral Dysfunction.

INTRODUCTION: Myobrace® is an orthodontic device that has the purpose of correcting oral dysfunctions, thus predisposing the physiological growth of the jaws, aligning teeth, and optimizing face development. This device is usually associated with Myobrace® Activities to reach this target. Considering the lack of studies in the literature about peripheral blood oxygen saturation (SpO2) and the use of preformed oral devices, the aim of this study is to quantify the change in blood oxygen saturation (SpO2) in patients treated with the Myobrace® System in mixed dentition. MATERIALS AND METHODS: In this study, 23 children (11 females and 12 males) were involved, who were affected by different oral dysfunctions and were treated with a Myobrace®. Blood oxygen saturation measurements were taken at baseline and after every four months for a year. The SpO2 measurements were taken in the rest position and with a closed mouth for a total of 12 min-6 min with and 6 min without the Myobrace® oral device. All data points were anonymized and recorded on an Excel spreadsheet. A statistical analysis was carried out. RESULTS: Therapy with a Myobrace® in patients with mixed dentition resulted in a statistically significant increase in oxygen saturation. In particular, in patients with a closed mouth, a statistically significant increase in oxygen saturation was observed, bringing it from 97.66% to 99.00%, while in the rest position, the increase was from 98.03% to 99.07%. CONCLUSIONS: The use of Myobrace® devices in patients with mixed dentition could lead to a significant improvement in blood oxygen saturation.

[Effect of maxillary expansion combined with orofacial myofunctional therapy on the position of the tongue of children with mouth breathing].

Objective:This study aimed to investigate the change of the position of the tongue before and after combined treatment of maxillary expansion and orofacial myofunctional therapy in children with mouth-breathing and skeletal class Ⅱmalocclusion. Methods:A total of 30 children with skeletal class Ⅱ malocclusion and unobstructed upper airway were selected. The 30 children were divided into mouth-breathing group（n=15） and nasal-breathing group（n=15） and CBCT was taken. The images were measured by Invivo5 software. The measurement results of the tongue position of the two groups were analyzed by independent samples t-test. 15 mouth-breathing children with skeletal class Ⅱ malocclusion were selected for maxillary expansion and orofacial myofunctional therapy. CBCT was taken before and after treatment, the measurements were analyzed by paired sample t test with SPSS 27.0 software package. Results:The measurement of the tongue position of the mouth-breathing and nasal-breathing groups were compared, the differences were statistically significant（P<0.05）. The measurement of the tongue position showed significant difference after the combined treatment of maxillary expansion and orofacial myofunctional therapy in children with mouth-breathing and skeletal class Ⅱmalocclusion（P<0.05）. Conclusion:Skeletal class Ⅱ malocclusion children with mouth-breathing have low tongue posture. The combined treatment of maxillary expansion and orofacial myofunctional therapy can change the position of the tongue.

The efficacy of orofacial myofunctional therapy in oral dysphagia accompanying temporomandibular dysfunction.

OBJECTIVE: Patients with temporomandibular dysfunction (TMD) may develop oral-stage dysphagia (OD) in the chronic phase. METHODS: This study investigated the effect of orofacial myofunctional therapy (OMT) in individuals with TMD-related OD. Fifty-one patients aged 18-65 years with TMD-related OD were separated into three groups using a simple randomization method: the control group (n = 12) underwent patient education and a home-exercise program; additionally, to an exercise program the manual therapy (MT) group (n = 19) received MT; and the OMT group (n = 20) received the OMT program. MT and OMT were applied in two sessions per week for 10 weeks. The patients were re-evaluated after treatment and at 3 months. RESULTS: The OMT group showed the most improvement in jaw functionality, swallowing-related quality of life, pain, and dysphagia (p < .05). DISCUSSION: OMT was superior to MT and exercises alone in reducing dysphagia and improving the swallowing-related quality of life.

The Effects of Orofacial Myofunctional Therapy on Children with OSAHS's Craniomaxillofacial Growth: A Systematic Review.

Orofacial myofunctional therapy (OMT) is one of the therapeutic methods for neuromuscular re-education and has been considered as one of the auxiliary methods for obstructive sleep apnea hypopnea syndrome (OSAHS) and orthodontic treatment. There is a dearth of comprehensive analysis of OMT's effects on muscle morphology and function. This systematic review examines the literature on the craniomaxillofacial effects of OMT in children with OSAHS. This systematic analysis was carried out using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) standards, and the research was scanned using PICO principles. A total of 1776 articles were retrieved within a limited time, with 146 papers accepted for full-text perusing following preliminary inspection and 9 of those ultimately included in the qualitative analysis. Three studies were rated as having a severe bias risk, and five studies were rated as having a moderate bias risk. Improvement in craniofacial function or morphology was observed in most of the 693 children. OMT can improve the function or morphology of the craniofacial surface of children with OSAHS, and its effect becomes more significant as the duration of the intervention increases and compliance improves. In the majority of the 693 infants, improvements in craniofacial function or morphology were seen. The function or morphology of a kid's craniofacial surface can be improved with OMT, and as the duration of the intervention lengthens and compliance rises, the impact becomes more pronounced.

Agreement between telerehabilitation and face-to-face orofacial myofunctional assessment in persons with acquired brain injury.

BACKGROUND AND OBJECTIVE: Orofacial myofunctional disorders are common in persons with acquired brain injury. A new way for early detection of orofacial myofunctional disorders via information and communication technologies may improve accessibility. The purpose of this study was to evaluate the level of agreement between face-to-face and tele-assessment of an orofacial myofunctional protocol in a sample of persons with acquired brain injury. METHODS: A masked comparative evaluation was conducted in a local association of patients with acquired brain injury. Twenty-three participants (39.1% female, mean age of 54 years) with a diagnosis of acquired brain injury were included in the study. The patients followed a face-to-face and a real-time online assessment using the Orofacial Myofunctional Evaluation with Scores protocol. This is a protocol for evaluation with numerical scales that assess the physical characteristics and the main orofacial functions of patients including appearance, posture, and mobility of lips, tongue, cheeks, and jaws, respiration, mastication, and deglutition. RESULTS: The analysis showed excellent interrater reliability (ρ ≥ 0.85) for all the categories. In addition, most confidence intervals were narrow. CONCLUSIONS: This study reveals excellent interrater reliability of an orofacial myofunctional tele-assessment in patients with acquired brain injury in comparison with a traditional face-to-face evaluation.

Manipulating facial musculature with functional electrical stimulation as an intervention for major depressive disorder: a focused search of literature for a proposal.

BACKGROUND: Major Depressive Disorder (MDD) is associated with interoceptive deficits expressed throughout the body, particularly the facial musculature. According to the facial feedback hypothesis, afferent feedback from the facial muscles suffices to alter the emotional experience. Thus, manipulating the facial muscles could provide a new "mind-body" intervention for MDD. This article provides a conceptual overview of functional electrical stimulation (FES), a novel neuromodulation-based treatment modality that can be potentially used in the treatment of disorders of disrupted brain connectivity, such as MDD. METHODS: A focused literature search was performed for clinical studies of FES as a modulatory treatment for mood symptoms. The literature is reviewed in a narrative format, integrating theories of emotion, facial expression, and MDD. RESULTS: A rich body of literature on FES supports the notion that peripheral muscle manipulation in patients with stroke or spinal cord injury may enhance central neuroplasticity, restoring lost sensorimotor function. These neuroplastic effects suggest that FES may be a promising innovative intervention for psychiatric disorders of disrupted brain connectivity, such as MDD. Recent pilot data on repetitive FES applied to the facial muscles in healthy participants and patients with MDD show early promise, suggesting that FES may attenuate the negative interoceptive bias associated with MDD by enhancing positive facial feedback. Neurobiologically, the amygdala and nodes of the emotion-to-motor transformation loop may serve as potential neural targets for facial FES in MDD, as they integrate proprioceptive and interoceptive inputs from muscles of facial expression and fine-tune their motor output in line with socio-emotional context. CONCLUSIONS: Manipulating facial muscles may represent a mechanistically novel treatment strategy for MDD and other disorders of disrupted brain connectivity that is worthy of investigation in phase II/III trials.

Efficacy of orofacial myofunctional therapy combined with myofascial release in patients with mild obstructive sleep apnoea: a randomized controlled trial.

BACKGROUND: Obstructive sleep apnoea (OSA) is characterized by repetitive narrowing and collapse of pharyngeal airway during sleep, leading to apnoea or hypopnoea. In this context, myofunctional therapy and myofascial release might be effective, despite the literature on the combination of these approaches is still scarce. OBJECTIVES: This randomized controlled trial aimed to assess the efficacy of oro-facial myofunctional therapy combined with myofascial release in terms of functioning in patients with mild OSA. METHODS: Patients aged from 40 to 80 years with diagnosis of mild OSA were randomly allocated into intervention group (oro-facial myofunctional therapy plus myofascial release) and control group (only oro-facial myofunctional therapy). At the baseline (T0), after 4 weeks (T1), and after 8 weeks (T2), the following outcomes were assessed: apnoea/hypopnoea index (AHI), average oxygen saturation (SpO2 ), sleep time spent with oxygen saturation < 90% (T90), snoring index, and Pittsburgh Sleep Quality Index (PSQI). RESULTS: Out of the 60 patients enrolled, 28 (aged 61.46 ± 8.74 years) complete the treatment in the intervention group and 24 (aged 60.42 ± 6.61 years) in the control group. There were no significant differences in AHI between groups. A significant difference was reported for ΔT0-T1 SpO2 (p = .01), T90 (p = .030), ΔT0-T1 and ΔT0-T2 snoring index (p = .026 and <.001 respectively), and ΔT0-T1 and ΔT0-T2 Pittsburgh Sleep Quality Index (p = .003 and <.001 respectively). CONCLUSION: Taken together, a combination of oro-facial myofunctional therapy and myofascial release showed a potential treatment for sleep quality in patients with mild OSA. Future studies are necessary to better investigate the role of these interventions in OSA patients.

Assessment of Muscular Weakness in Severe Sleep Apnea Patients: A Prospective Study.

OBJECTIVE: There are no official diagnostic tools to evaluate the weakness of the genioglossus muscle. We have developed a protocol for muscular assessment in patients with severe obstructive sleep apnea-hypopnea syndrome (OSAHS) and evaluated its effectiveness. STUDY DESIGN: Case and controls prospective study. SETTING: Sleep Unit Hospital Quironsalud Marbella (Spain). METHODS: Twenty-nine cases and 20 controls were recruited. Patients were examined by a phonoaudiologist that performed biometric measurements and the Orofacial Myofunctional Evaluation With Scores (OMES), Friedman, and Epworth Sleepiness Scale (ESS). In addition, upper airway muscle strength measures were performed using the Iowa Oral Performance Instrument (IOPI) and Tongue Digital Spoon (TDS). RESULTS: The final cohort consisted of 49 subjects, including 29 cases and 20 controls. According to the univariate and multivariate logistic regression analyses, ESS, OMES protocol, IOPI score, and TDS were associated with severe OSAHS. Multivariate regression revealed an IOPI score below 48 kps with an adjusted odds ratio (OR) of 9.96 (95% confidence interval [CI] 2.5-39.1, p = .001), and a 0.72 specificity (Spe), a 0.79 sensitivity (Sens), and a 0.82 area under the curve (AUC). Similarly, an OMES score lower than 200 had an adjusted risk ratio of 4.02 (95% CI 2-7, p < .001), 1 Spe, 0.79 Sens, and 0.98 AUC; and finally, TDS scores lower than 201 g/cm2 showed an adjusted OR of 27 (95% CI 4.74-153.6, p = .0001), 0.66 Spe, a 0.93 Sens, and a 0.86 AUC. CONCLUSION: Our findings suggest that severe OSAHS patients present different muscle patterns than controls.
