The treatment of malocclusion after open reduction of maxillofacial fracture: a report of three cases

The posttraumatic complications of jaw fractures related to jaw function and facial deformity include nonunion, malunion, malocclusion, temporomandibular joint dysfunction and facial asymmetry. This report presents cases referred to our department for revision of malunion and malocclusion following inadequate reduction of jaw fractures. Three patients with posttraumatic malocclusions caused by malunion were treated with a LeFort I osteotomy in one case and re-fracture in two cases. All of the patients exhibited stable results without further complications (e.g., malunion or malocclusion). Accurate preoperative diagnosis and proper anatomical reduction of the fracture segments are essential to preventing post-surgical malunion and malocclusion.
