Brief summary
This study was planned to evaluate the accuracy of virtual surgical planning and three-dimensional (3D) printed templates in reconstruction of temporomandibular joint (TMJ) with costochondral graft.
Detailed description
Eight patients (15-45) years diagnosed with TMJ deformities were included. A composite skull model was obtained with data from computed tomography. A virtual surgical simulation was performed using Dolphin Imaging 11.7 Premium. Then, the virtual plan was transferred to the operative field using 3D (CAD-CAM) printed surgical template. These templates were designed by 3D printing using data from the virtual surgical simulation for optimum selection of the rib graft, accurate tailoring of chondral and costal graft and as an osteotomy guide. The preoperative measurement including mouth opening, facial asymmetry and differences between the actual mandibular position and the virtual plan were analyzed
Interventions
PROCEDUREvirtual temporomandibular joint reconstruction with costochondral graft
All patients were placed in preoperative occlusion in CASS. The planned rib was harvested in the standard manner through an inframammary incision. The length of the rib was equal to the prefabricated template as calculated in the cranial-maxillofacial 3D reconstruction, and comprised at most 5 mm of cartilage. The cartilage was trimmed and contoured to facilitate the setting of the cartilage side properly into the center of the TMJ fossa. A 4-hole titanium plate was fixed with four bicortical screws as previously planned
