Surgical treatment of chronic prolonged mandibular dislocation: case report and literature review

To investigate the treatment methods of chronic prolonged mandibular dislocation.

Surgical reduction was performed in a case of temporomandibular joint dislocation over 6 months after manual reduction failure. The flap was removed under general anesthesia, and the bone of the condyle were removed. The articular disc was aligned and incision was sutured, and the procedure was combined with intermaxillary fixation for a correct occlusion and traction. After the operation, the surgical efficacy was observed, and the related literature was reviewed.

The patient recovered well after the operation; the mouth opening was 3 cm, and the occlusion was normal. No recurrence was observed after 10 months of follow-up. The literature shows that surgery is a common treatment for temporomandibular joint dislocation after the failure of manual reduction, and postoperative patient education can reduce recurrence and complications.

Surgery combined with intermaxillary traction can effectively treat chronic prolonged mandibular dislocation.
