Types of Suture: Guide to Surgical Stitch Techniques

Sutures are essential in surgical procedures for wound closure and tissue healing. Understanding the types of suture helps healthcare professionals choose the right material and technique for each case. Sutures can be broadly categorized into absorbable and non-absorbable types. Absorbable sutures, such as polyglycolic acid or catgut, naturally dissolve in the body over time, making them ideal for internal tissues. Non-absorbable sutures, including silk, nylon, and polypropylene, provide long-term support and are often used in skin closure or cardiovascular surgery.

The types of suture also differ in structure, including monofilament, which reduces infection risk, and multifilament, which offers better knot security. Surgeons must consider tissue type, wound location, and healing requirements when selecting the suture. Other important factors include tensile strength, elasticity, and biocompatibility. Additionally, techniques such as interrupted, continuous, mattress, and subcuticular suturing play a crucial role in achieving optimal outcomes. By understanding the types of suture, medical practitioners ensure faster healing, minimal scarring, and reduced post-operative complications. Proper suture selection is key to surgical success.
