Cut tissue heals better when the edges are held together. A suture is a stitch or series of stitches used to approximate wound edges or soft tissues, and also the material with which those stitches are made.

Suture materials are absorbable or permanent, monofilament or braided, and chosen according to tissue type and tension. Techniques include interrupted, continuous, subcuticular, and specialized patterns for vessels or tendons. Proper placement distributes tension and minimizes dead space and scarring.

Removal timing for non-absorbable skin sutures depends on location and healing. Infection, dehiscence, and suture reactions are possible complications. Mastery of suturing is a fundamental surgical skill taught early and refined throughout a career.
