Effect of Blended Carbon Dioxide and Erbium:YAG Laser Energy on Preauricular and Ear Lobule Keloid Fibroblast Secretion of Growth Factors

Abstract

Combined CO2 and Er:YAG laser treatment decreases the production of TGF-beta1 in preauricular and ear lobule KFs. This laser may have clinical promise in the treatment of keloids. Finally, the different growth factor profiles obtained suggest that KFs from the ear lobule and preauricular regions are different.
