This systematic review and meta-analysis evaluated skeletal changes in Class III patients undergoing surgery-first approach (SFA) versus conventional orthognathic surgery (COS). Nineteen studies were analyzed, revealing that SFA resulted in greater upward and forward mandibular movement during the 3-6 month postoperative period, but no significant differences in skeletal stability were found between the two approaches from 6 months to 2 years postoperatively.
Key findings
- SFA showed greater upward and forward mandibular movement during the 3-6 month postoperative period.
- No significant differences in skeletal stability between SFA and COS were observed from 6 months to 2 years postoperatively.
- Relapse primarily occurred during the 3-6 month post-surgical interval, with SFA showing greater relapse than COS.
Why it matters
Understanding the differences in skeletal stability between SFA and COS is crucial for clinicians to optimize treatment planning and manage patient expectations, particularly regarding the risk of relapse during the early postoperative period.
