Low power laser irradiation has been shown to be effective in promoting wound healing. We studied low power He-Ne laser stimulation on wound healing experimentally and clinicaly. Round skin defect of 10mm in diameter were created on the both sides of ear of rabbits. They were divided in three groups and two of groups were treated using low power He-Ne laser irradiation at 1.3J/cm2. One group was point irradiation and the other was scanning irradiation. In the irradiated groups, skin defects were healed rapidly and neovascularization was created around the defects. Histological examination showed that process of wound healing was progressive obviously with minimal inflammatory changes. In clinical cases, laser irradiation was useful for the promotion of healing and some showed general effect of irradiation.
