Laser is useful for surgery to cut, coagulate, vaporized and weld the tissue.Recently, low power laser was utilized for treatment of ulcer. pain and vascular anastomosis. We applied low power Nd: YAG laser irradiation for skin approximation. An experimental study was carried out by using the Nd : YAG laser in approximating the surgically cut skin wound of guinea pigs. Wound healing condition was observed using a cell-maceration method with NaOH solution for SEM observation of connective tissue fiber on post operative the days of 7, 21 and 42 respectivery. The incised skin wound following laser approximation showed less scaring and faster healing than conventional suture technique.
This laser technique will be beneficial as one of the new procedures of skin suture in clinical practice. The results were discussed from both technical and cosmetic standpoint.
