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

Objective To investigate the treatment methods of chronic prolonged mandibular dislocation. Meth⁃ ods Surgical reduction was performed in a case of temporomandibular joint dislocation over 6 months after manual re⁃ duction failure. The flap was removed under general anesthesia, and the bone of the condyle were removed. The articu⁃ lar 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. Results 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 re⁃ duce recurrence and complications. Conclusion Surgery combined with intermaxillary traction can effectively treat chronic prolonged mandibular dislocation
