An understanding of the basic steps involved in wound healing allows the surgeon to close wounds without complications, loss of function, or poor cosmetic outcomes. Similarly, the correct choice of suture is also critically important. Suture can be classified under 2 broad categories: absorbable and nonabsorbable. Absorbable suture provides a temporary support scaffold until the wound itself can support the normal stresses and strains of tissue. Absorption of such suture can occur by hydrolysis or enzymatic degradation.3 Examples of absorbable suture include polyglactin 910 (Vicryl; Ethicon), poliglecaprone 25 (Monocryl; Ethicon), polyglycolic acid (Dexon II; Kendall Co, Mansfield, Massachusetts), polydioxanone, gut, chromic gut, and fast-absorbing gut. The first stage of absorption occurs with linear kinetics and lasts from days to weeks, depending on the type of suture. The second stage of suture degradation, which overlaps the first stage, results in a loss of suture mass. Nonabsorbable suture provides a permanent support scaffold and elicits fibroblasts to encapsulate the stitches. Nonabsorbable suture is frequently used to close the most superficial layer of skin and is removed once healing has occurred but before excessive granulation tissue and scarring around the suture occurs (usually 6-8 days). Examples of nonabsorbable suture include silk, steel wire, polyamide polymer (Ethilon; Ethicon), polypropylene (Prolene), and polyester (Mersilene; Ethicon).3 In 1992, Guyuron and Vaughan2 showed that there was no statistically significant difference between absorbable and nonabsorbable suture used for superficial closure with respect to hypertrophic scarring.
