Which type of suture material is considered absorbable?

Polyglycolic acid (PGA) is classified as absorbable suture material, which means that it is designed to be broken down by the body's biological processes over time. PGA is made from synthetic polymers and provides the advantage of supporting tissue healing while gradually being absorbed. This characteristic minimizes the need for suture removal after healing, enhancing patient comfort and reducing the risk of infection associated with retained external sutures.

In contrast, silk, nylon, and polyester are all non-absorbable suture materials. Silk is a natural fiber that does not break down in the body and remains indefinitely, while nylon and polyester, both synthetic materials, are also designed to maintain their structural integrity for extended periods. They may be used for applications where permanent support is required. Understanding the differences in suture material properties is essential for making appropriate choices depending on the surgical context and the healing timeline.
