Summary
Advancement flaps for facial defect repair can cause distortion. Mobilizing deep tissue layers, not undermining the lesion, minimizes tension and distortion for better flap recruitment and reduced lesion expansion.
Area of Science:
- Plastic Surgery
- Dermatological Surgery
- Surgical Innovation
Background:
- Advancement flaps are used for facial defect reconstruction.
- Potential limitations include secondary distortion, lesion expansion, and wound tension.
Purpose of the Study:
- To evaluate a modified technique for advancement flap closure in facial defects.
- To minimize secondary distortion and lesion expansion during wound closure.
Main Methods:
- Advancement flaps were raised in piglets to simulate serial excision of skin lesions.
- A novel technique involving mobilization of deep fascial layers was compared to undermining lesion-bearing skin.
Main Results:
- Undermining lesion-bearing skin led to lesion expansion and was counterproductive.
- Mobilizing a separate layer of hypodermis and fascia deep to the lesion reduced wound tension.
- This technique maximized advancement flap recruitment and minimized residual lesion expansion.
Conclusions:
- Mobilizing deep tissue layers offers a superior method for advancement flap closure compared to undermining.
- This technique effectively bridges defects with minimal tension, preserving anatomical landmarks and reducing lesion spread.
