The aim of the present study was to evaluate the effects of two treatments for masseteric hypertrophy. In total, 24 patients with masseteric hypertrophy were enrolled in this study. Patients were randomly divided into two groups: 12 individuals were treated with radiofrequency (RF) ablation and 12 patients received an injection of botulinum toxin A. The thickness of the masseter muscle under te...

Masseteric hypertrophy, popularly called the benign masseteric hypertrophy (BMH) or idiopathic masseteric hypertrophy (IMH) is a relatively uncommon condition characterized by asymptomatic enlargement of one or both masseter muscles and is rarely accompanied by pain, which is often confused with parotid swelling. Most frequently, clinicians are consulted for swelling of angle of mandible which ...

The importance of masticatory muscle function on the growth and differentiation of condyle was examined. The aim of this study was to investigate how reduced masticatory muscle function influences intrinsic regulatory factors which govern growth and differentiation of condylar cartilage. Masseter muscles of 3-week-old Wistar rats were resected bilaterally. Masseteric resected animals and corres...

INTRODUCTION AND OBJECTIVES Micro-neurovascular free muscle flap transfer is currently the procedure of choice for long-standing facial paralysis. We present a case series of patients treated with gracilis muscle free flap with motor innervation by the masseteric nerve. We discuss the surgical technique and quantify the movement granted by the muscle, the improvement in quality of life and aest...

Several mechanisms have been hypothesized to contribute to the rapid hyperemia at the onset of exercise. The aim of the present study was to investigate the role played by the mechanosensitivity of the vascular network. In 12 anesthetized rabbits blood flow was recorded from the exclusively muscular masseteric artery in response to brief spontaneous contractions (BSC) of the masseter muscle, ar...

Masseter muscle hypertrophy is a rare condition characterized by unilateral or bilateral enlargement of the masseter muscle affecting both males and females following puberty. It usually manifests in late adolescence or early adulthood. Its etiology remains unknown. Masseter muscle hypertrophy produces facial asymmetry and familiarity with this condition is important to rule out other pathologi...
