permanent facial paralysis is a catastrophic event for involved patients. in long lasting paralysis with severe facial muscles atrophy, masseter muscle transfer is a very good choice. but its greatest problem is postoperative elongation of flap and gradual diminishing of early results and loss of symmetry. this article advocate a new modification for resolving this problem with concomitant elev...

Background: EMG (electromyography) has been used to determine the masticatory efficiency of the muscles of mastication. Method: In this study, Temporalis and Masseter muscle activity of patients with unilateral missing mandibular 1 molar were evaluated pre and post rehabilitation with three unit fixed partial denture prosthesis. Six male and four female patients, within the age range of 17–35 y...

AIM To determine the relationship between bilateral allodynia induced by masseter inflammation and P2X3 receptor expression changes in trigeminal ganglia (TRG) and the influence of intramasseteric P2X3 antagonist administration on bilateral masseter allodynia. METHODS To induce bilateral allodynia, rats received a unilateral injection of complete Freund's adjuvant (CFA) into the masseter musc...

Integrins are heterodimeric cell surface membrane proteins linking the extracellular matrix to actin. α7B integrin is detected in proliferating and adult myofibers, whereas α7A plays a role in regenerating muscle fibers with a minor function in mature muscle fibers. The expression levels of β1A appear to be very low, whereas β1D appears to be the ...

OBJECTIVE To study the bilateral differences in the thickness of the masseter muscles in untreated individuals with lateral crossbite, as well as in subjects with successfully treated functional lateral crossbite, at least three years after the end of treatment. MATERIALS AND METHODS Three groups of growing individuals were studied: (1) untreated group: 38 individuals with unilateral crossbit...

Dr. (Mrs.) Chandralekha .B, MDS Former Head of the Department of Orthodontics, Government Dental College & Hospital, Fort, Bangalore 560 001. Ph: 09448-091115 The present study investigated the effect of masseter muscle thickness on maxillary dental arch width and growth pattern of face. Sample comprised of 40 patients, (20 females, 20 males) between 18 to 23 years. They were subdivided accordi...

Rabies virus pathogenesis was studied in a mouse model by inoculation of the masseter muscle. At different intervals, the masseter muscle, trigeminal ganglia, and brain were analyzed for virus-specific RNA with a polymerase chain reaction assay, which revealed that as early as 18 h postinfection (p.i.), virus-specific RNA was present in the trigeminal ganglia, and at 24 h p.i., viral RNA was id...

background: the existence of a pathophysiological link between headaches and muscle activity pattern is still being debated. the purpose of this study was to investigate the effect of pain on the timing pattern of the masseter muscle in patients with tension-type headache (tth) and migraine without aura (moa). methods: 57 women (22 controls, 19 moa and 16 tth) participated in the study. the ele...

The purpose of the present investigation was to study the relationship between the ultrasonographic thickness of the masseter muscle and the width of the maxillary dental arch. The sample comprised 60 consecutive orthodontic patients (37 females, 23 males), 7-18 years of age with a Class I relationship and minor malocclusion. The thickness of the masseter muscle was measured ultrasonographicall...
