“…Szyszka-Sommerfeld et al, analyzed masticatory muscle activity by means of sEMG in children surgically treated for unilateral complete cleft lip and palate [14]. Surface electromyography also provided the basis for assessing masticatory muscle activity in patients with other congenital maxillofacial anomalies, such as hemifacial microsomia or craniosynostosis [15,16]. sEMG was used to evaluate masticatory muscle function while monitoring orthodontic therapy in subjects with Down syndrome [17,18].…”

Background: Cleft lip and palate is one of the most common congenital malformations that affect patients, quality of life in the long term and require multidisciplinary medical care until adulthood. There are several surgical techniques used to correct a unilateral cleft lip and all of these techniques aim to restore functional and aesthetic aspects toensure the continuation of the normal growth and development of the craniofacial structures. Numerous studies have reported these surgical outcomesaccording to aesthetic criteria. However, there exists alack of knowledge about, is this surgical technique achieved functional aspects. Accordingly, this review aims to answer this question. Materials and Methods: The study included needle electromyography test for both the Orbicular Muscle of Mouth,Elevator muscle of Upper Lip and Wing of Nose in 10 complete unilateral cleft lip patients aged 2,5-4 years who underwent a primarysurgical repair of the lip at the age of three months with Tennison technique in the department of Oral and Maxillofacial Surgery, Tishreen hospital, Lattakia, Syria. Results: The result showed no significant statistical difference in muscle activity values fort heOrbicular Muscle of Mouth and Elevator muscle of Upper Lip and Wing of Nose in both cleft and noncleft side (P>0.05). Conclusion: Using of Tennison technique restores the closest anatomical positioning to muscle fibers of studied muscles.

“…14 Development of the evaluation techniques for this study was previously applied and standardized by the research team. 12,17 Surface EMG has been widely used for the evaluation of the masseter muscle in international literature and proven to be reliable due to the volume and superficial position of the muscle. Since bite force assessment can be altered due to several variables such as pain, dental status, and periodontal support, each patient served as a self-control, thus eliminating any interpersonal differences.…”

“…Bite force depends largely on the muscular elements that allow the temporomandibular joint to work appropriately, with the masseter being the most prominent muscle in this group. 12 Is it possible that masseter muscle denervation alters the biomechanics of mastication, resulting in a reduction in bite force that could limit a patient's oral intake?…”

Introduction The masseter nerve has been used as a donor nerve for facial reanimation procedures due to the multiple advantages it offers; it has been generally considered that sacrifice of the masseter nerve does not alter the masticatory apparatus; however, there are no objective studies to support this claim. Objective To evaluate the impact that the use of the masseter nerve in dynamic facial reconstruction has on the electrical activity of the masseter muscle and on bite force. Materials and Methods An observational and prospective longitudinal study was performed measuring bite force and electrical activity of the masseter muscles before and 3 months after dynamic facial reconstructive surgery using the masseter nerve. An occlusal analyzer and surface electromyography were employed for measurements. Results The study included 15 patients with unilateral facial paralysis, with a mean age of 24.06 ± 23.43. Seven patients were subjected to a masseter–buccal branch nerve transfer, whereas in eight patients, the masseter nerve was used as a donor nerve for gracilis free functional muscle transfer. Electrical activity of the masseter muscle was significantly reduced after surgery in both occlusal positions: from 140.86 ± 65.94 to 109.68 ± 68.04 (p = 0.01) in maximum intercuspation and from 123.68 ± 75.64 to 82.64 ± 66.56 (p = 0.01) in the rest position. However, bite force did not show any reduction, changing from 22.07 ± 15.66 to 15.56 ± 7.91 (p = 0.1) after the procedure. Conclusion Masseter nerve transfer causes a reduction in electromyographic signals of the masseter muscle; however, bite force is preserved and comparable to preoperative status.

Electromyography (EMG) is the most objective and reliable method available for imaging muscle function and efficiency, which is done by identifying their electrical potentials. In global surface electromyography (sEMG), surface electrodes are located on the surface of the skin, and it detects superimposed motor unit action potentials from many muscle fibers. sEMG is widely used in orthodontics and maxillofacial orthopaedics to diagnose and treat temporomandibular disorders (TMD) in patients, assess stomatognathic system dysfunctions in patients with malocclusions, and monitor orthodontic therapies. Information regarding muscle sEMG activity in subjects with congenital maxillofacial abnormalities is limited. For this reason, the aim of this review is to discuss the usefulness of surface electromyography as a method for diagnosing muscle function in patients with congenital malformations of the maxillofacial region. Original papers on this subject, published in English between 1995 until 2020, are located in the MEDLINE/PubMed database.
