Summary
Ovine forestomach matrix (OFM) supports split-thickness skin grafts (STSGs) for scalp reconstruction, improving contour defects. This biomaterial acts as a scaffold, promoting successful graft take and epithelialization in a single stage.
Area of Science:
- Biomaterials Science
- Regenerative Medicine
- Plastic Surgery
Background:
- Split skin grafts for scalp defects often result in contour deformities.
- Current reconstruction methods may not fully restore aesthetic and functional outcomes.
Purpose of the Study:
- To evaluate ovine forestomach matrix (OFM) as a dermal scaffold for split-thickness skin grafts (STSGs) in scalp reconstruction.
- To assess the efficacy of OFM in improving contour defects and graft take in scalp reconstruction.
Main Methods:
- OFM was applied to the periosteum after tumor excision, followed by an STSG.
- Graft take, epithelialization, and cosmetic outcomes were monitored in participants.
Main Results:
- Over 95% graft take and 100% epithelialization were observed in most participants within two weeks.
- One participant experienced lower graft take due to infection and necrosis.
- OFM demonstrated remodeling with well-vascularized dermal regeneration and ordered collagen deposition.
Conclusions:
- Ovine forestomach matrix serves as an effective temporary dermal scaffold for STSGs.
- OFM facilitates single-stage scalp reconstruction with improved cosmetic results.
- This biomaterial shows potential for enhancing reconstructive surgery outcomes.
