Z-plasty
Pronunciation: ZEE-plas-tee
Surgical technique using Z-shaped incisions to lengthen scars and change their direction.
Full Definition
Z-plasty is a fundamental plastic surgery technique that involves creating Z-shaped incisions to transpose adjacent triangular skin flaps. This method effectively lengthens contracted scars, changes scar direction to align with relaxed skin tension lines, and redistributes tension across the wound. The technique is particularly useful for releasing linear contractures, improving the appearance of unfavorable scars, and correcting web formations in areas like the axilla or web spaces of fingers. Multiple Z-plasties can be performed in series for longer contractures, and the angle of the Z can be varied to achieve different degrees of lengthening.
Usage
Usage note: Always hyphenate Z-plasty and specify the angle when clinically relevant.
