One-Stage treatment for maxillofacial asymmetry with orthognathic and contouring surgery using virtual surgical planning and 3D-printed surgical templates.

Abstract

Asymmetry is one of the most common maxillofacial deformities. One-stage treatment for maxillofacial asymmetry with orthognathic and contouring surgery has been rarely reported. This retrospective study aims to investigate the feasibility of simultaneous orthognathic and facial bone contouring surgery with the help of virtual surgical planning and 3D-printed navigation templates for facial asymmetry. From January 2012 to December 2015, 51 patients diagnosed with maxillofacial asymmetry received treatment of combined orthognathic and contouring surgery under the guidance of virtual surgical planning and 3D-printed templates. Photographs and measurements were taken before and after operation to evaluate the effectiveness of the treatment. Photographs and cephalometric analysis showed the asymmetry was effectively corrected. All patients were satisfied with the aesthetic results. This study suggested the clinical feasibility of simultaneous orthognathic and contouring surgery for the treatment of maxillofacial asymmetry. Virtual surgical planning and 3D-printed surgical templates enable the surgeons to plan and carry out the procedure more predictably and achieve satisfactory outcomes.
