RODRIGUES, Vitor Pereira et al. Intraoral approach for surgical treatment of bilateral masseter muscle hypertrophy. Rev. Assoc. Paul. Cir. Dent. [online]. 2012, vol.66, n.3, pp. 194-199. ISSN 0004-5276.

The masseter muscle hypertrophy is a rare condition characterized by a increased muscle size. In most cases is associated with a bone spur leading to a prominent mandibular angle. The etiology is uncertain, usually associated with parafunctional habits, psychiatric illness and disorders of the temporomandibular joint. Diagnosis is clinic but complementary exams are necessary to exclude other pathologies frequent in parotid masseteric region. Many ways of treatment are described in the literature such as the clinic treatment, medicamentous treatment and botulinic toxin type A injection and finally the surgical treatment. This last therapeutic method has several techniques that basically differ from each other by the kind of tissue that is manipulated: muscle, osseous or both and about the approach: intra or extra oral may be chosen.
