The role of the argon laser for the treatment of port wine stain (PWS) is reviewed in relation to the Southampton regime, which is based on finding the minimal blanching power. Both the advantages and limitations of this form of treatment are discussed, stressing the importance of first obtaining a

โฆ Synopsis
A total of 66 patients with port wine stains is reported. All of these were tested and 46 patients treated (80 treatments). Good to excellent results (significant lightening of color and/or smoother texture of skin) was achieved in 74% of tests (0 scar) and in 82% of treatments (4.3% scar). Treatment results correlate well with test spots but vary somewhat as the lesions are not homogenous and skin textures vary. The lowest energy density commensurate with successful treatment should be used to reduce the incidence of scarring. Future methods of manipulating the PWS may make it possible to achieve better results with less scarring. Teenagers fared well in this series, while the problem of successful treatment in the young child remains unsolved.

Optimal port wine stain treatment requires the selective absorption of light by the ectatic blood vessels. We investigated whether deeper blood vessels can be coagulated, without damaging other cutaneous structures, by varying the laser beam diameter. The penetration of the light was simulated with
One hundred fourteen patients were studied to assess their perception of the results of argon laser therapy for port wine stains (PWS), tattoos, or essential telangiectasia of legs. At least 1 yr following treatment patients were surveyed using a 30item mail questionnaire. A 91 % response rate was a
Thirty-seven patients of mean age 52 with large dark nodular port wine stains were treated with argon and neodymium YAG lasers. The level of patient satisfaction was high (mean 7.1 on scale of 10) despite residual color in 36 of 37 patients. It was possible to accomplish flattening of the lesion and
## Abstract ## Background and Objective During laser therapy of port wine stain (PWS) birthmarks, regions of perfusion may persist. We hypothesize that such regions are not readily observable even when laser surgery is performed by highly experienced clinicians. The objective of this study was to
## Abstract The use of the argon laser in the treatment of the port wine stain is discussed and its mode of action and the features of a port wine stain, which may be used to predict a good response to therapy, are described. Reference is made to the wide variation in techniques used in treatment
