Purpose: The reconstruction of unilateral large-sized mandibular contour defects with no loss of continuity and good occlusion has been a challenge. The purpose of the current study was to evaluate the effect of using patient-specific titanium mesh scaffolding avascular pure iliac bone graft in reconstructing these defects.
Materials and Methods: From December 2017 to December 2020, thirteen patients with unilateral large-sized mandibular contour defects treated in Orthognathic and TMJ Surgery Center of West China Stomatology Hospital were enrolled in this retrospective study. Patient-specific titanium meshes and mandible models were designed and manufactured by computer-aided design/
computer-aided manufacturing based on reverse engineering after mirroring the unaffected mandibular side. Linear and angular measurements comparing preoperative and postoperative mandibular CT scans were used to analyze the symmetries of mandibular contour postoperatively.
Results: The measurements showed satisfactory 3D symmetries of mandibular contour with significant improvement of the facial symmetry as a whole compared to the preoperative status of all participating patients.
Conclusion: Titanium mesh scaffolding iliac crest bone graft is a successful and feasible combination for reconstructing unilateral large-sized mandibular contour defects. This approach can be added to surgeons’ armamentarium improving the reconstruction outcomes.
