Z-plasty
Surgical technique using Z-shaped incisions to relieve tension and improve tissue mobility, often used in anal procedures.
Full Definition
Z-plasty is a plastic surgical technique that involves creating Z-shaped incisions to rearrange tissue, relieve tension, and improve mobility or length of structures. In pediatric gastroenterology and colorectal surgery, Z-plasty techniques are commonly employed during anal reconstructive procedures, particularly in cases of imperforate anus or anal stenosis. The technique redistributes tension forces and can help prevent contractures. The term is hyphenated when used as a noun and should maintain consistent capitalization of the 'Z' throughout medical documentation.
Usage
Usage note: Always hyphenate and capitalize the Z; distinguish from other plasty techniques.
