Mandibular Reconstruction with a Patient-Specific Custom Internal Fixation Plate and Free Fibula Flap: Insights from Two Cases

Abstract

 CosmoFix^® is a novel patient-specific custom internal fixation plate created by three-dimensional printing using computed tomography data, and it offers high-level strength based on stress analysis. However, its rigidity precludes intraoperative reshaping, thereby necessitating design adjustments before it can be used with free vascularized bone grafts (VBG). Despite the growing adoption of CosmoFix^®, its application with VBG has not been reported to date. In this study, the authors discuss two cases involving the combination of CosmoFix^® with a free fibular flap, a type of VBG, detailing institutional innovations.
