Surgically assisted rapid maxillary expansion – A case report = Expansão rápida da maxila cirurgicamente assistida - Um relato de caso = Expansión maxilar rápida asistida quirúrgicamente: Informe de un caso

Surgically assisted rapid maxillary expansion (SARME) is a combination of surgical and orthodontic procedures, indicated for the treatment of true transverse skeletal deficiencies in skeletally mature individuals. The present report presents a clinical case of SARME, performed under local anesthesia, by a multidisciplinary team, in an outpatient setting. The treatment plan began with the placement of a Hyrax type of orthodontic appliance. In the surgical procedure, horizontal and vertical osteotomies were performed, followed by median palatine suture disjunction. Expansion was performed by daily activation of the disjunctor appliance. After disjunction, orthodontic treatment began to align and level the teeth. On conclusion of treatment, effective expansion of the maxillary arch was observed, with correction of maxillary atrophy and anatomofunctional improvement of the stomatognathic system. In view of the result obtained, it was concluded that SARME is an effective multidisciplinary treatment for the correction of transverse deficiencies of the maxilla.
