Hypertrophy of the masticatory muscles is characterized by generalized enlargement of the muscular tissue that affects the facial esthetic and may or not be accompanied by pain [1-3]. This condition can be congenital, but more often it is acquired. The origin has been attributed to muscle hyperactivity and parafunctionsoriginated from stressful lifestyle that causes bruxing or clenching [2,3]. Masseteric muscle hypertrophy is a relative common clinical entity that can affect one or both sides and is also thought to causesecondary enlargement of the mandibular angle as a result of functional remodeling. Temporalis muscle hypertrophy is a rare clinical entity and only a few cases are reported. More often, it presents a bilateral involvement and is usually associated with masseteric hypertrophy [3]. The aim of this report is to present a case of bilateral temporalis and masseteric muscles hypertrophy treated surgically
