Superolateral dislocation of the intact mandibular condyle: our experience and review of the literature

Abstract

Anteromedial fracture dislocations of the mandibular condyle are frequently encountered in clinical practice; however, superolateral dislocations of an intact condyle represent a considerably rare case. Remarkably, the occurrence of such dislocations unaccompanied by any associated fractures is even rarer. In this study, we present a case of superolateral dislocation of an intact mandible in a 43-year-old male patient following a road-traffic accident. Manual reduction successfully repositioned the displaced intact mandibular condyle, resulting in normal mouth opening after the release of intermaxillary fixation (IMF). Favorable occlusion was confirmed one month postoperatively. Additionally, this paper meticulously examines previously documented case reports to shed light on the causative mechanisms, dynamic characteristics, diagnostic features, and optimal management strategies pertaining to such unusual dislocations, incorporating a comprehensive review of the existing literature. By addressing this infrequent condition, our study aims to ascertain the fact that superolateral dislocation of the mandibular condyle can occur without any associated fractures.
