Summary
Thinning perforator flaps using macroscopic techniques safely reduces flap thickness for defect coverage. This method offers a viable alternative to supermicrosurgery, achieving excellent clinical outcomes.
Area of Science:
- Plastic Surgery
- Microsurgery
- Reconstructive Surgery
Background:
- Perforator flaps are crucial for defect reconstruction.
- Flap thinning techniques are continuously evolving.
- This study evaluates established flap thinning methods.
Purpose of the Study:
- To assess the efficacy and safety of macroscopic flap thinning techniques.
- To compare different flap thinning approaches in cadaveric and clinical settings.
- To determine the potential of flap thinning for achieving thin, viable perforator flaps.
Main Methods:
- Two cadaveric studies were conducted to analyze perforator anatomy and fat dissection.
- Colored latex solution was used to visualize vascular patterns.
- A clinical series of 15 patients underwent flap thinning procedures.
Main Results:
- Average flap thickness reduction ranged from 32.76% to 53.41% across different flap types (ALT, DIEAP, TAP, MSAP).
- Dissection of the deep fat layer was performed guided by vascular patterns.
- 13 out of 15 clinical cases achieved satisfactory outcomes with significant thickness reduction.
Conclusions:
- Macroscopic flap thinning safely removes the deep fat layer, creating thin yet viable perforator flaps.
- This technique is effective in achieving desired flap thinness.
- Surgeons should consider macroscopic flap thinning as a valuable option before adopting supermicrosurgery.
