SHARP DISSECTION, ELECTROSURGERY, AND ARGON-ENHANCED ELECTROSURGERY IN PORCINE SKIN FLAPS

Sharp scalpel dissection, electrosurgery, and argon-enhanced electrosu rgery (argon beam coagulation) were used to elevate random pedicled sk in flaps in a randomized, blinded fashion with a porcine model. A tota l of 72 flaps on 9 pigs were examined, Flap survival was quantified, a nd histology was also reviewed 2 and 6 weeks after surgery, No signifi cant difference among the three techniques was noted in terms of area or length of surviving flaps, There were also no histologic difference s noted with regard to fibrosis, inflammatory infiltrate, or necrosis, We conclude that the use of electrosurgery during surgical dissection of random pedicled skin flaps is not detrimental to wound healing or tissue survival, and it provides benefits such as decreased blood loss , absence of the need for sharp instruments in the surgical field, and faster operative times.
