Summary
Mandibular osteotomy for prognathia correction showed relapse in over half of patients, often linked to myofunctional issues. Interdisciplinary planning is crucial for stable, long-term results in treating jaw deformities.
Area of Science:
- Dentistry
- Orthognathic Surgery
- Cephalometric Analysis
Context:
- Analysis of 23 prognathic patients undergoing mandibular osteotomy.
- Comparison of cephalometric data with dental model analysis.
- Long-term follow-up (≥6 years) including pre-operative, post-operative, and follow-up assessments.
Purpose:
- To evaluate the stability and outcomes of isolated mandibular osteotomy in correcting dental and skeletal discrepancies.
- To assess the influence of pre-existing conditions like macromandibulosis and associated maxillofacial discrepancies.
- To identify factors contributing to relapse after surgical correction.
Summary:
- Pre-surgery, most patients exhibited macromandibulosis, often with midface deficiency and dento-alveolar compensation.
- Surgical correction achieved stability in 14 patients, with 9 experiencing some degree of relapse.
- A significant correlation was found between relapse and the presence of myofunctional disturbances.
Impact:
- Highlights the potential for relapse in isolated mandibular osteotomies for prognathia.
- Emphasizes the critical role of myofunctional status in long-term treatment success.
- Recommends interdisciplinary treatment planning for predictable and stable outcomes in complex maxillofacial cases.
