✦ Synopsis

Port wine stains are currently treated by the argon laser with the "point-by-point" technique, or the "painting technique." In both cases, the quality of the results depends greatly on the dermatologist's experience. Furthermore, the first technique is slow, and the second is painful and requires anesthesia. Therefore, we have decided to design a robotized system with the following specifications: easy, fast, nonpainful treatment giving a homogeneous and reproduceable blanching. The system is made of a handpiece with the scanning mechanism and a control box with the microprocessor. The system is independent of the laser (no electrical connection) and has its own power meter. The deposit of energy was optimized in function of heat diffusion in the skin. Over a 12-month period, 123 patients were treated with the robotized handpiece. The treatment modalities and the results conformed to the above-mentioned specifications. Hypertrophic scars were not reported. Therefore, we think that this system will be an interesting tool for the laser treatment of port wine stains and other cutaneous angiodysplasias.

## Abstract ## Background and Objectives Pulsed dye lasers (PDL; 585 nm, 0.45 millisecond) are the treatment of choice for port wine stains (PWS). However, clearance rates vary widely and are in many patients incomplete. The objective of this prospective pilot study was to investigate the effects
