Description
Background : Mandibular reconstruction using a fibular graft is a difficult procedure that requires technical expertise to enable adequate occlusal function and restore an aesthetic appearance. Here we used three-dimensional (3D) sodium chloride (NaCl) models for simulated mandibular reconstruction surgery. This study aimed to reveal the accuracy of mandibular reconstruction with fibular grafts using this model. Methods : Mandibular reconstructions using 3D NaCl models were performed in 5 cases. The maxilla, mandible, and fibular models were developed using computed tomography (CT) data. We performed preoperative cutting and simulation surgery using this model. Angles between the body of the corpus and symphysis were measured from the axial view (n = 4). Angles between the ramus and the body of the corpus were measured from the lateral and axial views (n = 6). These angles were measured on simulated models and postoperative CT images were compared. Results : Differences between the angles measured on the simulated models and postoperative CT images were 0-5°(mean, 1.9°). Conclusions : We were able to reproduce the neomandibles with precise osteotomies using the 3D NaCl models. We believe that simulated mandibular reconstruction surgery using this model might help reduce the number of intraoperative neomandibular segment adjustments.
