What incision technique is used in a Z-plasty?

• A. Central incision parallel to the contraction
• B. Central incision perpendicular to the contraction
• C. Incision along the tension lines of the skin
• D. Curved incision around the contracture

Answer: (B)

In Z-plasty, the technique used involves making a central incision that is perpendicular to the direction of the contraction. This design allows for the creation of triangular flaps of skin that can be shifted to relieve the contracture and elongate the skin. The perpendicular nature of the incision is crucial because it allows for the effective release of the contracted area while simultaneously creating new tension lines that improve the functional and aesthetic appearance of the skin. This method effectively rearranges the skin and subcutaneous tissue, redistributing the tension and improving mobility over the affected area. In contrast, other incision techniques may not provide the same level of functional improvement and could compromise skin integrity or aesthetics. The Z-plasty is particularly beneficial in areas where skin contractures occur, and it is a widely used technique in scar revision and reconstruction in podiatric surgery, among other specialties.
