title: Treatment of telangiectases and other benign vascular lesions with the 577 nm pulsed dye laser.
abstract: BACKGROUND
  This study was undertaken to evaluate the effectiveness and safety of the 577 nm pulsed dye laser in the treatment of various vascular lesions of the face.
  
  
  OBJECTIVE
  Our purpose was to make observations on the effects of different variables that could affect response.
  
  
  METHODS
  Ninety-two adults with telangiectases of the face were sequentially selected for treatment according to a protocol previously established. Evaluation consisted of visual inspection by two investigators, and before and after photographs at 2-months intervals. A few patients with other vascular lesions were also treated and reported.
  
  
  RESULTS
  Ninety-one percent of the patients (84 of 92) showed good to excellent response after a single treatment. Recurrence occurred in 2%. Atrophy of the skin occurred in 2%. Venous lakes, pyogenic granulomas, and mucosal vascular malformations showed significant improvement.
  
  
  CONCLUSIONS
  The 577 nm pulsed dye laser is effective and safe for vascular lesions of the face.
