Unilateral Benign Masseteric Hypertrophy: Surgical Intervention and Case Report

Hypertrophy is related to an enlargement caused by a growth in the size but not in the number of cells. Generalized masticatory muscle hypertrophy may affect the temporalis muscle, masseters, and medial pterygoids in a variety of combinations. Masseter hypertrophy is recognized as a rare disorder and persistent asymptomatic enlargement of one or both masseter muscles. Etiology for benign masseteric hypertrophy is unknown in most of the cases so considered as idiopathic. Although numerous factors such as facial asymmetry, trismus, protrusion, bruxism, clenching, malocclusion, or temporomandibular disorders have been reported on the basis of clinical examination and cited previous literatures but have not proven still. This article reports a case of unilateral benign masseter hypertrophy with retrognathic mandible in which surgical intervention was rendered to the patient by using a combination approach.
