Temporomandibular joint (TMJ) dislocation involves a non-self-limited displacement of the condyle out of its functional positions within the glenoid fossa and posterior aspect of the articular eminence. TMJ dislocation accounts for 3 % of all reported dislocated joint cases in the body. The TMJ is more flexible in women and therefore more prone to dislocation. Chronic dislocations include acute dislocations that are not self-limiting and progress without treatment, as well as recurrent chronic dislocations, in which individuals experience multiple dislocations as a result of daily activities. Regardless of the subtype, chronic dislocation can be managed by surgical or non-surgical treatment modalities. Surgical/invasive interventions aim at anatomical modification of the eminence, condyle, or musculocapsular tissues. We report the case of a 75-year-old female patient who was admitted to the Oral and Maxillofacial Surgery service of the Hospital de Traumatología y Ortopedia “Dr. Victorio de la Fuente Narváez” in Mexico City for presenting recurrent mandibular dislocation on the left side for 3 years. It was decided to perform eminoplasty with chin graft as a definitive surgical treatment for this condition, obtaining excellent functional results up to one year of follow-up.
KEY WORDS: joint dislocations, temporomandibular joint, temporal bone, bone graft.
