Management of superolateral dislocation of the mandibular condyle: a retrospective study of 10 cases.

Abstract

INTRODUCTION:

Superolateral dislocation of the mandibular condyle (SDMC) is rarely described. The best treatment for superolateral dislocation of the fractured mandibular condyle (SDMC) is debated. This study investigated selection of the timing and techniques used in treating these fractures.

PATIENTS AND METHODS:

A retrospective clinical study was conducted on clinical data from 10 SDMC patients. Maximum mouth opening and occlusal relationships were compared following treatment using different techniques.

RESULTS:

The 10 patients were followed for 6-25 months. Patients who had dislocation for less than 1 week had condylar reduction and rigid internal fixation of the fractures. Mandibular sagittal split ramus osteotomy and articular reduction and fixation were performed in seven cases. Postoperative mouth opening and occlusal relationships were satisfactory in all patients with the exception of one case with mouth opening of only 27 mm.

CONCLUSIONS:

For all patients with superolateral dislocation, our first approach was to reduce the bone stump through surgery. When the dislocated joint had become adherent to the surrounding tissues and ankylosis developed, mandibular sagittal split ramus osteotomy was performed with good results.
