Skeletal and Soft-Tissue Stability Following Advancement Genioplasty: A Comparative Analysis between Wire and...

Area of Science:

• Oral and Maxillofacial Surgery
• Orthodontics
• Plastic Surgery

Background:

• Genioplasty is a standard procedure for correcting dentofacial deformities.
• Assessing osseous and soft-tissue stability is crucial for genioplasty outcomes.
• Comparing fixation methods aids in optimizing surgical results.

Purpose of the Study:

• To compare osseous and soft-tissue stability after advancement genioplasty.
• To evaluate the efficacy of wire versus plate osteosynthesis in genioplasty.
• To determine the optimal fixation method for different magnitudes of chin advancement.

Main Methods:

• Ten patients undergoing advancement genioplasty were divided into two groups (n=5 each).
• Group I utilized plate osteosynthesis; Group II used wire osteosynthesis for stabilization.
• Lateral cephalograms were analyzed preoperatively and 6 months postoperatively using Park et al. method.

Main Results:

• Both fixation methods resulted in significant aesthetic improvements.
• Wire fixation showed slightly more horizontal relapse compared to plate fixation, though not statistically significant.
• The mean osseous to soft-tissue sagittal change ratio was 1:0.88 for plates and 1:0.80 for wires.

Conclusions:

• Plate osteosynthesis demonstrated a marginal advantage in stability over wire osteosynthesis.
• Plate fixation is recommended for genioplasties involving larger chin advancements.
• The choice of fixation method should be individualized based on case-specific requirements.
