The aim of this study was to test the hypothesis that experimental and reversible changes of occlusion affect the levels of surface electromyographic (SEMG) activity in the anterior temporalis and masseter areas during unilateral maximal voluntary biting (MVB) in centric and eccentric position. Changes were achieved by letting 21 healthy subjects bite with and without a cotton roll between the ...

Objectives: Brainstem is the most frequently affected neural substrate in neurological involvement due to Behçet’s disease (neuro-Behçet). The demonstration of brainstem involvement in Behçet’s disease (BD) is important in the management of this disorder. The evaluation of some brainstem reflexes (blink reflex and exteroceptive suppression of masseter) and brainstem auditory evoked potentials (...

BACKGROUND As ultrasonography provides objective parameters and values, it is a reliable method of examining the structure dimensions masseter muscle. Although well known, there no standardization in clinical examination data analysis yet. OBJECTIVES The study aimed to measure muscle thickness designated areas establish most repeatable clinically applicable ultrasound examination, assess differ...

CONTEXT Facial palsy is a common problem encountered in clinical practice. These patients suffer serious functional, cosmetic & psychological problems with impaired ability to communicate. Functional problems around the eye are usually a first priority for the patient with facial palsy.The nerve to masseter as a direct nerve transfer to the zygomatic branch of facial nerve to reinnervate viable...

MASSETER MUSCLE ACTIVITY RESULTING FROM STIMULATION OF HYPOTHALAMIC BEHAVIORAL SITES: A WAVELET ANALYSIS by Anne Marie Petrock Patterns of electromyographic (EMG) activity can give an insight into muscle activity associated with a given behavioral state. The masseter muscle is positioned closely to the temporomandibular joint and controls the position and movement of the jaw. The hypothalamus i...

A 19-year-old male patient presented with facial hemi-atrophy with unilateral spasms of the masseter and temporalis muscles. Ultrasound therapy and Transcutaneous Electric Nerve Stimulation therapy, known as combination therapy, were given on alternate days for 2 weeks. At the end of 2 weeks of combination therapy the patient reported a drastic reduction in the number of episodes of muscle spas...

The ultrasonographic images of 32 patients with inflammatory change in the masseteric region were investigated to clarify the characteristic findings and to evaluate the utility of ultrasonography. Inflamed masseter muscles frequently demonstrated reduction of echo intensity and complete or partial absence of hyperechoic bands. The mean thickness of the masseter muscle on the unaffected side wa...
