Abstract Reconstruction of segmental mandibular defects is in a continuous state of evolution utilizing the recent advances in preoperative Virtual Surgical Planning (VSP). The anterior iliac crest is one of the ideal reservoirs for autogenous harvesting of bone graft with rapid and predictable consolidation. Objectives: To evaluate the morphological and functional accuracy of VSP guided mandibular reconstruction surgery using anterior iliac crest bone graft. Materials and methods: Eight patients with lateral segmental mandibular defects were selected. All defects were reconstructed using anterior iliac crest non-vascularized bone graft, utilizing preoperative virtual surgical planning and intraoperative resection and reconstruction guides. Patients were evaluated clinically for pain, recipient site healing, and donor site healing. In addition, a radiographic three-dimensional investigation was performed immediately to determine the accuracy of the VSP. Results: All of the operated patients showed a statistically significant improvement in the clinical parameters. Regarding the radiographic performance, all of the patients regained the continuity of the lower border. All of the linear and angular measurements reported a statistically insignificant difference between the APM and the VSP values, delineating the morphological and functional accuracy of the virtual plane. Conclusion: Computer-assisted reconstruction showed accurate postoperative condylar position and morphological orthognathic measurements in mandibular resection cases with iliac crest graft reconstruction. |
