OBJECTIVE: To describe a cross-sectional study of TMJ dislocation in a Brazilian level-one trauma center. METHODS: The data were collected and analyzed from electronic medical records in a period from 2013 to 2020. RESULTS: Bilateral TMJ dislocation occurred in the majority of cases, being reduced by the Nélaton maneuver associated with Barton's bandage. The average time between the dislocation and specialist appointment was 30.69 hours. Elderly patients were associated with an increased number of recurrent dislocations ( CONCLUSION: The literature is still scarce concerning demographic data, treatment modalities, and follow-up. More studies are necessary to better understand TMJ dislocation management.
