A surgical technique used in reconstructive surgery
Z-plasty is a surgical technique used in reconstructive surgery to improve the functional and cosmetic appearance of scars. It is a type of plastic surgery that involves the rearrangement of tissue to change the direction of a scar, lengthen a contracted scar, or improve the contour of a scar.
Technique[edit]
Z-plasty involves the creation of two triangular flaps of skin that are transposed to change the direction of a scar. The basic design of a Z-plasty consists of a central limb and two lateral limbs, forming a "Z" shape. The central limb is aligned with the scar, and the lateral limbs are created at an angle to the central limb.
Steps[edit]
1. Incision: The surgeon makes an incision along the central limb of the "Z" and then along the two lateral limbs. 2. Flap creation: Two triangular flaps are created by the incisions. 3. Transposition: The flaps are transposed, meaning they are moved and rotated to cover the opposite triangular defect. 4. Closure: The flaps are sutured into their new positions, effectively changing the direction of the scar.
Applications[edit]
Z-plasty is commonly used in the following situations:
- Scar revision: To improve the appearance of scars, especially those that are linear and cause functional limitations.
- Contracture release: To release scar contractures, which are tight bands of scar tissue that can limit movement.
- Cosmetic improvement: To make scars less noticeable by aligning them with natural skin lines or folds.
Advantages[edit]
- Lengthening effect: Z-plasty can lengthen a scar, which is beneficial in releasing contractures.
- Reorientation: The technique can change the direction of a scar, making it less conspicuous.
- Improved contour: It can improve the contour of a scar, making it blend better with the surrounding skin.
Limitations[edit]
- Complexity: The procedure requires precise planning and execution.
- Risk of complications: As with any surgical procedure, there is a risk of complications such as infection, bleeding, or poor healing.
