Several studies, mostly case series, have been published on the Nd:YAG laser (1064 nm). A case series showed persistent flattening of keloids or hypertrophic scars in 5 (22.7%) of 22 scars 12 months after Nd:YAG treatment. [100] A clinical trial obtained a reduction in the size of the scars of 10% or greater in 8 (36.4%) of 22 patients treated with Nd:YAG at 3- to 4-week intervals. [101] The Nd:YAG laser appears to improve the cosmetic appearance of keloids and may be a superior treatment modality than PDL lasers. [102]
