Inhibitory effects of low-level laser therapy on skin-flap survival in a rat model

Background Although several studies have demonstrated the effects of low-level laser therapy (LLLT) on skin flap viability, the role of higher doses has been poorly investigated. Objective To investigate the inhibitory effect of the LLLT (λ=670 nm) on the viability of random skin flaps in a rat model using an irradiation energy of 2.79 J at each point. Methods Sixteen Wistar rats were randomly assigned into two groups: sham laser irradiation...
