A randomized, split-face clinical trial of Q-switched alexandrite laser versus Q-switched Nd:YAG laser in the treatment of bilateral XXXX .

@entity1 @entity13687 @entity158
Different types of Q-switched (QS) lasers have been used successfully to treat @entity13687 . The purpose of this study was to compare the clinical efficacy and complication of QS alexandrite (QS Alex) laser versus QS neodymium:yttrium aluminum garnet (Nd:YAG) (QS Nd:YAG) laser for bilateral @entity13687 . Seventeen @entity1 with bilateral @entity13687 were treated randomly with QS Alex in one half of face and QS Nd:YAG in the other half with an interval of at least 3 months between each. Subjective assessment was made by both @entity1 and dermatologists. @entity1 were also examined for evidence of complications. All @entity1 experienced improvement (p < 0.05). There was no statistically significant difference between the two sides (p > 0.05). The @entity158 after a short period of laser therapy was more severe for QS Alex than for QS Nd:YAG laser. Vesicles developed in 1 @entity1 after QS Alex therapy. Both QS Alex laser and QS Nd:YAG laser were equally effective at improving bilateral @entity13687 . @entity1 tolerate QS Nd:YAG laser better than QS Alex laser.
