Types of Suture: Materials, Uses & Healing Guide

Types of suture play a vital role in modern surgical and wound-closure techniques. Sutures are medical threads used to close cuts, surgical incisions, or wounds, helping tissues heal properly while reducing the risk of infection. Understanding the different types of suture allows healthcare professionals to choose the most effective option for each clinical situation.

Sutures are broadly classified into absorbable and non-absorbable types. Absorbable sutures, such as catgut, polyglycolic acid, and polylactic acid, naturally dissolve in the body over time and are commonly used for internal tissues. Non-absorbable sutures, including silk, nylon, polypropylene, and polyester, remain in place until removed and are often used for skin closure or long-term support.

Another important classification of types of suture is based on structure: monofilament sutures consist of a single smooth strand that reduces infection risk, while multifilament sutures are braided for better knot security. Selecting the right suture depends on wound type, healing time, tissue strength, and patient condition.

A clear understanding of the types of suture ensures optimal wound healing, minimal scarring, and improved surgical outcomes.
