Summary
This study analyzed current orthognathic surgery techniques in maxillofacial surgery. Results show established methods like Obwegeser/dal Pont are widely used and effective, with plates and screws being common fixation materials.
Area of Science:
- Maxillofacial Surgery
- Orthognathic Surgery
- Surgical Techniques
Background:
- Orthognathic surgery, a cornerstone of maxillofacial surgery, has evolved over a century.
- Advancements in plate and screw osteosynthesis have significantly enhanced surgical stability and safety.
- Numerous techniques for mandibular repositioning are currently employed.
Purpose of the Study:
- To provide evidence-based data on the current utilization of various mandibular repositioning techniques.
- To analyze the preferred surgical methods and osteosynthesis materials in international clinical practice.
Main Methods:
- An international multicenter analysis involving 51 hospitals.
- Data collection on the frequency of use for different surgical techniques (Obwegeser/dal Pont, Hunsuck/Epker, Perthes/Schlössmann).
- Assessment of commonly used osteosynthesis materials (plates, bicortical screws, or combinations).
Main Results:
- The Obwegeser/dal Pont technique was most dominant (61%), followed by Hunsuck/Epker (37%) and Perthes/Schlössmann (29%).
- Plates (82%) were the primary osteosynthesis material, followed by bicortical screws (23.5%).
- 47% of centers reported using multiple surgical methods concurrently based on patient anatomy and surgeon preference.
Conclusions:
- Current surgical methods for mandibular repositioning in orthognathic surgery are comparable, safe, and reliable in clinical practice.
- The choice of technique often depends on specific anatomical challenges and surgeon expertise.
- Further prospective studies are warranted to identify potential patient benefits of different approaches.
