Summary
Surgical orthodontic treatment plans are often modified before surgery, with 27.5% of cases experiencing changes. Key reasons include jaw width, movement amount, and patient condition, emphasizing the need for flexible surgical planning.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthodontics
- Surgical Planning
Background:
- Orthognathic surgery requires initial treatment plans, but these are frequently revised prior to the procedure.
- Understanding the modification process in surgical orthodontic treatment is crucial for optimizing outcomes.
Purpose of the Study:
- To investigate the frequency and reasons for modifications in surgical orthodontic treatment plans.
- To provide insights into the dynamics of surgical technique changes during orthognathic surgery.
Main Methods:
- Analysis of 501 patients undergoing orthognathic surgery between April 2005 and March 2024.
- Survey data collected on surgical technique changes, reasons for modification, and initial consultation details.
- Results categorized into three 5-year periods to identify trends.
Main Results:
- Surgical techniques were modified in 138 cases (27.5%).
- Common reasons for changes included jaw width, extent of jaw movement, occlusal planes, rotation/cant, and patient condition.
- The most frequent modification involved the addition or omission of LeFort I osteotomy.
Conclusions:
- Preoperative review and potential modification of initial treatment plans are essential in managing jaw deformities.
- Adaptive surgical planning minimizes patient burden and enhances occlusal stability.
