Abstract
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

Summary
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 [1,2,3]. This condition can be congenital, but more often it is acquired. 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 clinical evaluation showed a marked bilateral swelling involving the temporalis and masseter muscles (Figures 1-3). Panoramic radiograph showed marked enlargement of both mandibular angles (Figure 6)
