RODRIGUES, Danillo Costa et al. Unilateral Masseter Muscle Hypertrophy: Case Repor. Rev. cir. traumatol. buco-maxilo-fac. [online]. 2013, vol.13, n.4, pp. 21-26. ISSN 1808-5210.

Masseter muscle hypertrophy is a unilateral or bilateral enlargement of the masseter muscle, of undefined etiology, which in most cases generates an aesthetic discomfort, and in some cases a functional one as well. The affected individuals often exhibit an increase in bone mass in the region of the branch and mandibular angle, and the treatment can use surgical or nonsurgical methods. The surgical approach involves intervetions performed in either the compromised muscle or the mandibular angle bone structure, or in both. This article describes a case of unilateral masseter muscle hypertrophy, where the surgical resection of the muscle fibers in an intraoral approach and a osteotomy with a reciprocating saw were performed in the mandibular angle region. After a two-month follow-up, it was observed that the surgical approach for the treatment of masseter hypertrophy is well advised, since the aesthetic results are excellent, with similarity to the contralateral side of mandibular angle.
