Effects of laser, scalpel, and electrosurgical excision on wound contracture and graft "take".
Current literature recommends the use of a carbon dioxide laser for excision of lesions where minimal damage and wound contracture are desirable. The extent of tissue damage is evaluated as a correlate of percentage of split-thickness skin graft "take" following excision of full-thickness skin with scalpel, electrocutting current, or carbon dioxide laser. The poorest overall percentage "take" is apparent following laser excision, while the highest overall percentage "take" occurs following scalpel excision. Wound contracture, an inherent part of wound healing, is reportedly minimal or clinically inapparent with laser excision. On the contrary, this experimental evaluation suggests that wound contracture following laser excision is at least as great if not greater than that following other methods of excision when a split-thickness skin graft is applied to the wound bed.
