RESUMO: A anquilose da ATM caracteriza-se pela substituição dos tecidos articulares por tecido ósseo ou fibro-ósseo, gerando uma união entre os componentes ósseos da articulação, tal alteração gera comprometimento da função articular. A anquilose da ATM quando ocorre na infância pode prejudicar o crescimento mandibular, causando posteriormente uma assimetria facial severa entre outros. Sua etiopatogenia é variável, desde traumas até reações a injeções intra-capsulares de medicamentos.O correto diagnóstico só é obtido por meio de avaliação clínica e radiográfica, incluindo tomografia computadorizada e reconstruções em 3D-TC. Há diferentes modalidades cirúrgicas para seu tratamento, artroplastia em GAP, Artroplastia Interposicional utilizando-se da interposição de um material biológico ou não, e a reconstrução conjunta da ATM, com enxertia de osso autógeno ou prótese articular total, todas preconizando ressecção agressiva da massa anômala fibrosa e/ou óssea.O presente trabalho visa relatar cirurgia de remoção de massa anquilótica óssea em ATM  no serviço de CTBMF do HFSE do RJ. Paciente do sexo feminino, 7 anos, melanoderma, AMI de 15mm, acesso Al-Kayat, ressecção de massa anquilótica óssea, coronoidectomia bilateral, revestimento com aba miofascial de temporal, enxerto autógeno costocondral. Paciente evoluiu com AMI de 35mm e acompanhamento de 2 anos. Demonstrando eficácia e previsibilidade do tratamento escolhido, segundo protocolo Kaban.Palavras-chaves: Anquilose de ATM; Enxerto Costocondral; ArtroplastiaInterposicional; Protocolo Kaban                                                                 ABSTRACT: TMJ ankylosis is characterized by the replacement of the joint tissues by bone or fibro-osseous tissue, generating a union between the bone components of the joint, such alteration causes compromised joint function. TMJ ankylosis when it occurs in childhood may impair mandibular growth, causing severe facial asymmetry and mandibular retrusion, difficulty in phonation, among others. Its etiopathogenesis varies from traumas to reactions to intra-capsular injections of medications. Correct diagnosis is only obtained through clinical and radiographic evaluation, including computed tomography and 3DCT reconstructions. There are different surgical modalities for its treatment, GAP arthroplasty, Interpositional arthroplasty using the interposition of a biological material or not, and the joint reconstruction of TMJ, with autogenous bone excision or total joint prosthesis, all of which advocate aggressive resection of the anomalous mass fibrosis and / or bone. The present study aims to report bone ankylosis mass removal surgery in TMJ in the CTBMF service of the HFSE of RJ. Female patient, 7 years old, melanoderma, 15 mm AMI, general anesthesia, Al-Kayat access, bone ankylotic mass resection, bilateral coronoidectomy, temporal myofascial flap coating, autochondral costochondral graft. Patient evolved with 35mm AMI and 2 year post-operative follow-up. Demonstrating effectiveness and predictability of the treatment chosen, according to Kaban protocol. Keywords: TMJ ankylosis; Costochondral Graft, Interpositional Arthroplasty;Kaban Protocol

In dentistry, temporomandibular joint (TMJ) ankylosis is a rare pathology where no consensus of global population data has been found and therefore has presented a challenge for professionals, since there are no treatment sequence protocols standardized. The objective is to carry out a literature review and update of the diagnosis of ankylosis, considering its clinical characteristics, classification, etiology, and epidemiology. Giving special emphasis to the types of treatments used and concluding that GAP interpositional arthroplasty and TMJ reconstruction arthroplasty would be the best options to improve maximum oral opening in a patient with ankylosis, thus allowing him to recover function and aesthetics.
