title: Scientific basis for the selection of skin closure techniques.
abstract: This scientific article was designed to teach the individual reader the scientific basis for suture and needle selection as well as to illustrate the appropriate surgical techniques involved in wound repair of skin incisions. Because the US Food and Drug Administration permits 1.5% of the sterile surgical gloves to have holes, the operating room personnel should wear sterile surgical double-glove hole indication systems that detect holes in the outer glove. From the surgeon's point of view, the rate of gain of strength of the skin wound is a key determinant of many decisions including when the suture can be removed, the level of patient activity, and the selection of the incision. Important considerations in wound closure are type of suture and mechanical performance, in vivo and in vitro. Measurements of the in vivo degradation of sutures separate them into two general classes, absorbable and nonabsorbable. Sutures that undergo rapid degradation in tissues, losing their tensile strength within 60 days, are considered absorbable. Those that maintain their tensile strength for longer than 60 days are considered nonabsorbable. For skin closure with nonabsorbable suture, we favor the use of the polybutester suture that is coated with an absorbable polymer, VASCUFIL™. When absorbable sutures are used for a dermal skin closure, the synthetic monofilament MAXON™ is recommended. Absorption of the suture is complete between 90 and 110 days. In either case, we would recommend that the suture be attached by a sewage attachment to a SURGALLOY™ reverse cutting stainless steel suture. Continuous percutaneous suture closure has definite, distinct advantages over interrupted suture closure. Although continuous dermal wound closure is technically more challenging for the surgeon than interrupted dermal suture closure, it has become an important wound closure technique. A monofilament absorbable synthetic MAXON™ attached to a reverse cutting edge SURGALLOY™ stainless steel needle is ideally suited for continuous dermal skin suture closure.
