Profile of patients with TMJ dislocation in a level-1 emergency hospital: A cross-sectional study

ABSTRACT

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 (p = 0.03). Furthermore, a longer dislocation time was associated with the reduction under intravenous (IV) sedation (p < 0.05).

Conclusion

The literature is still scarce concerning demographic data, treatment modalities, and follow-up. More studies are necessary to better understand TMJ dislocation management.
