Summary
Researchers developed six novel skin flaps for reconstructing triangular defects, outperforming traditional methods in tension management. These new flaps, including the spider crab and mantis designs, were successfully used in 40 patients.
Area of Science:
- Plastic Surgery
- Surgical Innovation
- Biomechanical Engineering
Background:
- Traditional skin flaps primarily address circular defects post-tumor removal.
- Reconstruction of triangular surgical defects remains a challenge with limited flap options.
Purpose of the Study:
- To introduce and evaluate novel skin flap designs specifically for triangular surgical defects.
- To utilize an innovative experimental model for flap design and testing.
Main Methods:
- New flap designs were tested on a pig skin model using a tension sensor.
- Flap performance was assessed under varying basal tension conditions.
- Comparison with established flap techniques was conducted.
- Successful clinical application in a series of 40 patients with triangular defects.
Main Results:
- Six new flap designs (spider crab, mantis, toy windmill, nautilus, origami bird, clover) were successfully developed.
- All new flaps demonstrated adequate tension levels.
- Spider crab and mantis flaps exhibited superior performance under increased basal tension.
- Successful clinical outcomes were achieved in 40 patients.
Conclusions:
- Six innovative skin flaps for triangular defects have been presented.
- The experimental model effectively evaluated flap biomechanics.
- Clinical application confirmed the efficacy and safety of the new flaps, particularly spider crab and mantis designs.
