Autologous fat grafting in orthognathic surgery reduces facial swelling. This procedure lessened postoperative edema, leading to a faster and greater resolution of swelling by 12 weeks.
Area of Science:
- Plastic Surgery
- Oral and Maxillofacial Surgery
Background:
- Autologous fat grafting is a valuable addition to orthognathic surgery.
- Fat grafting may possess anti-inflammatory effects.
Purpose of the Study:
- To evaluate the impact of fat grafting on facial edema following orthognathic surgery.
- Assessing the magnitude, duration, and resolution rate of facial edema.
Main Methods:
- Retrospective cohort study analyzing 3D photographs.
- Comparison between fat-grafted and non-fat-grafted cohorts.
- Statistical analysis using t-tests and linear regressions.
Main Results:
- Facial volume increased by 23.7% postoperatively.
- Swelling decreased by 62% by week 12.
- Fat grafting accelerated edema resolution without increasing initial swelling.
Conclusions:
- Postoperative facial edema typically resolves by 12 weeks.
- Fat grafting in orthognathic surgery reduces edema magnitude and speeds resolution.
- Fat grafting is a beneficial adjunctive procedure for managing postoperative swelling.
