Background: The neuromuscular activity has a critical role in the permeability of the upper airways.
Objective: The present study aimed to conduct a detailed and comparative investigation of the orofacial musculature and motor skills of children with obstructive sleep apnea (OSA).
Materials And Methods: Children aged 7 to 12 years with OSA (OSA group, n = 12) and without OSA (Control group, n = 12) were compared.
Objective: Dentofacial deformities (DFD) require orthodontic treatment, orthognathic surgery, and speech therapy for aesthetic and functional problems. This longitudinal study analyzed changes in masticatory function and three-dimensional (3D) facial soft tissue in patients with Class II and Class III DFD after orthognathic surgery. In addition, the study investigated the relationship between facial measurements, maximum bite force (MBF), and orofacial myofunctional status (OMS).

Objective: To evaluate the oral motor function in obese individuals.
Material And Methods: Three observational cross-sectional studies were performed.
The treatment of a complex temporomandibular disorder (TMD), such as disk displacement with reduction (DDR) associated with arthralgia and myalgia, may depends on understanding the impairments in muscle function. The aim of this study was to investigate the behavior of the anterior temporalis, masseter and sternocleidomastoid muscles in the time and frequency domains during chewing in patients with chronic painful TMD-DDR using electromyographic (EMG) analysis. Thirty-three patients who met the diagnostic criteria for TMD and 32 volunteers without TMD (control group) underwent clinical examination, chewing pattern classification and EMG analysis.

Objective: To investigate whether chronic TMD patients had any changes in tongue strength, besides the difficulty in chewing and orofacial functional impairment, compared to a control group. Moreover, to examine whether tongue strength, chewing difficulties, and orofacial functions were associated.
Objective: Sjögren's syndrome (SS) induces difficulty in chewing and swallowing due to low salivary flow. However, these symptoms may be associated with other factors, such as orofacial myofunctional disorders and temporomandibular disorder (TMD), which have not been comprehensively assessed in this population. The aims of this study were to investigate orofacial muscles and functions as well as the presence of TMD in patients with SS compared with a group without SS and to analyze whether the patients' experience of limitations in orofacial functioning is associated with the orofacial functional status and muscle pain related to TMD.

Moreover, it was examined whether swallowing variables and a valid clinic measure of orofacial myofunctional status were associated.
Material And Methods: Twenty-three patients with chronic TMD, diagnosed with disc displacement with reduction (DDR) and pain, according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), and 27 healthy volunteers (control group) were compared.
Purpose: Orofacial myofunctional therapy (OMT) is a modality of treatment for children and adults with obstructive sleep apnea (OSA) to promote changes in the musculature of the upper airways. This review summarizes and discusses the effects of OMT on OSA, the therapeutic programs employed, and their possible mechanisms of action.
Methods: We conducted an online literature search using the databases MEDLINE/PubMed, EMBASE, and Web of Science.
Objective: To evaluate the reliability, validity, and responsiveness of the Italian OMES (I-OMES).
Patients And Methods: The study consisted of 3 phases: (1) internal consistency and reliability, (2) validity, and (3) responsiveness analysis. The recruited population included 27 patients with orofacial myofunctional disorders (OMD) and 174 healthy volunteers.
Objectives: To introduce an index (Masticatory Stability Index, MSI) to analyze the stability of chewing cycles in standardized conditions and test it in a group of patients with subclinical mild temporomandibular disorder (TMD).
Design: 23 subjects with mild subacute TMD and 21 healthy subjects were involved; they all responded to a questionnaire about signs and symptoms of TMD (ProTMDmulti) and underwent a myofunctional orofacial evaluation with scores, using the protocol of orofacial myofunctional evaluation with scores (OMES). Their mandibular kinematics was assessed with a 3D motion capture system during deliberate unilateral gum chewing.
Objective: To investigate whether reorganization of muscle activity occurs in patients with chronic temporomandibular disorders (TMD) and, if so, how it is affected by symptomatology severity.
Methods: Surface electromyography (sEMG) of masticatory muscles was made in 30 chronic TMD patients, diagnosed with disc displacement with reduction (DDR) and pain. Two 15-patient subgroups, with moderate (TMDmo) and severe (TMDse) signs and symptoms, were compared with a control group of 15 healthy subjects matched by age.
Functional impairments of facial expressions alter the quality of life and their quantitative analysis is key to describing and grading facial function and dysfunction. The aim of this investigation was to quantify 3D lip movements in a group of healthy young subjects. Lip movements during five repetitions of common and random sequences of vowels and nonverbal expressions were recorded using an optoelectronic 3D motion analyzer.

Methods: Participants were 39 children (mean age 8 ± 1.2 years) of which, 27 had a diagnosis of OSA and 12 had PS.
Purpose: To compare a new normalization technique (wax pad, WAX) with the currently utilized cotton roll (COT) method in surface electromyography (sEMG) of the masticatory muscles.
Methods: sEMG of the masseter and anterior temporalis muscles of 23 subjects was recorded while performing two repetitions of 5s maximum voluntary clenches (MVC) on COT and WAX. For each task, the mean value of sEMG amplitude and its coefficient of variation were calculated, and the differences between the two repetitions computed.
Objective: The objective of the present study is to investigate if changes in the oxygen saturation of masseter muscle during a chewing task can differentiate patients with myogenic temporomandibular disorders (TMD) from healthy subjects and if these differences are related to the gravity of the disorder and to the orofacial myofunctional status.
Materials And Methods: Twelve women with moderate TMD (TMD group; 37 ± 16 years) and ten healthy control women (CTRL group 24 ± 5 years) participated. Validated protocols were used to evaluate the severity of TMD and the orofacial myofunctional status.
This study investigated the efficacy of combining low-level laser therapy (LLLT) with oral motor exercises (OM-exercises) for rehabilitation of patients with chronic temporomandibular disorders (TMDs). Eighty-two patients with chronic TMD and 20 healthy subjects (control group) participated in the study. Patients were randomly assigned to treatment groups: GI (LLLT + OM exercises), GII (orofacial myofunctional therapy-OMT-which contains pain relief strategies and OM-exercises), and GIII (LLLT placebo + OM-exercises) and GIV (LLLT).

Because in the Italian language there is no validated tool for such purpose, this study was developed.
Purposes: To translate and culturally adapt the OMES-protocol for Italian language and determine the normal score value in a group of young Italian adults.
There is no standardized protocol for the clinical evaluation of orofacial components and functions in patients with obstructive sleep apnea. The aim of this study was to examine the validity, reliability, and psychometric properties of the Expanded Protocol of Orofacial Myofunctional Evaluation with Scores (OMES-expanded) in subjects with obstructive sleep apnea. Patients with obstructive sleep apnea and control subjects were evaluated, and the validity of OMES-expanded was tested by construct validity (i.

This study assessed the orofacial functions, including surface electromyography (EMG) of dynamic rhythmic activities, in patients with moderate-severe signs and symptoms of chronic TMD. It was hypothesized that orofacial motor control differs between patients with moderate-severe chronic TMD and healthy subjects.
