Arcuate Osteotomy Genioplasty With Bridging Titanium Fixation

Conventional genioplasty often results in palpable facial step deformities. Recent advancements utilizing arcuate osteotomy combined with bridging four-hole titanium plate fixation have optimized bone segment repositioning and stabilization, significantly improving contour continuity. This technique represents a critical innovation in maxillofacial reconstruction. The procedure was performed via intraoral approach. An arcuate osteotomy line was designed 0.5 cm below the apices of anterior teeth, avoiding bilateral mental foramina. Three bridging titanium plates were contoured for anatomical reduction and rigid internal fixation. Postoperative follow-up showed mild nerve injury and imperceptible step deformities upon chin palpation. 1. Arcuate Osteotomy: Aligns with the natural mandibular curvature, eliminating angular transitions caused by linear osteotomy while combining biomechanical stability with neuroprotective advantages, suitable for complex corrections. 2. Bridging Plates: Ensure precise fixation to minimize bone displacement, increase osteotomy alignment surface area, and promote osteogenesis. Their low-profile design enhances contour harmony through anatomical adaptation. The integration of arcuate osteotomy and bridging titanium plate fixation achieves natural aesthetic outcomes with reduced complication risks, establishing a new paradigm for precision treatment in maxillofacial surgery.
