Abstract
Background and Objectives The purpose of this study was to determine the role of helium–neon (He–Ne) laser random skin flap viability in rats. Study Design/Materials and Methods Experimentally controlled randomized study.Forty‐eight Wistar‐EPM rats were used, weighed, and divided into 4 groups with 12 rats each. The random skin flap was performed measuring 10×4 cm, with a plastic sheet interposed between the flap and the donor site. The Group 1 (control) underwent sham irradiation with He–Ne laser. The Group 2 was submitted to laser irradiation, using the punctual contact technique on the skin flap surface. The Group 3 was submitted to laser irradiation surrounding the skin flap, and the Group 4 was submitted to laser irradiation both on the skin flap surface and around it. The experimental groups were submitted to He–Ne laser irradiation with 3 J/cm2 energy density immediately after the surgery and for the four subsequent days. The percentage of necrotic area of the four groups was calculated at the 7th post‐operative day, through a paper‐template method. Results Group 1 reached an average necrotic area of 48.86%; Group 2, 38.67%; Group 3, 35.34%; and Group 4, 22.61%. After the statistic analysis, results showed that all experimental groups reached statistically significant values when compared to the control group, and Group 4 was the best one, when compared to all groups of this study (P<0.001). Conclusion The He–Ne laser irradiation was efficient to increase random skin flap viability in rats.Keywords
