What Is the Most Stable Fixation Technique for Mandibular Condyle Fracture?

PURPOSE

Mandibular condylar fractures are relatively common fractures, accounting for 29 to 52% of all mandibular fractures. Recently, the debate between closed versus open treatment of the condylar fracture has shifted toward more specific surgical questions concerning the number and pattern of the fixation method for the condylar region. We have attempted to resolve the controversy with the systematic review and meta-analysis. The purpose of the present study was to compare the outcomes of different methods of fixation for mandibular condylar fractures.

MATERIALS AND METHODS

We conducted an electronic database search for clinical studies evaluating the stability of internal fixation of condylar fractures. The search was restricted to studies reported in the English language from January 2000 to July 2018. The review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement guidelines.

RESULTS

The initial search returned 285 studies reported from January 2000 through July 2018. After reviewing the full-text reports, only 16 studies were deemed eligible for the review. The total sample size was 831 patients with mandibular subcondylar fractures. The patients were classified into 25 groups according to the fixation method, follow-up period, use of intermaxillary fixation, and the presence of associated fractures.

CONCLUSIONS

The results of our systematic review and meta-analysis showed that single plate fixation has been associated with more complications with poor outcomes, including hardware failure, screw loosening, and postoperative malocclusion.
