BACKGROUND Current treatment of facial capillary malformations (CM) has limited efficacy.

OBJECTIVE To assess the efficacy of large spot 532 nm lasers for the treatment of previously treated facial CM with the use of 3-dimensional (3D) image analysis.

PATIENTS AND METHODS Forty-three white patients aged 6 to 59 were included in this study. Patients had 3D photography performed before and after treatment with a 532 nm Nd:YAG laser with large spot and contact cooling. Objective analysis of percentage improvement based on 3D digital assessment of combined color and area improvement (global clearance effect [GCE]) were performed.

RESULTS The median maximal improvement achieved during the treatment (GCEmax) was 59.1%. The mean number of laser procedures required to achieve this improvement was 6.2 (range 1–16). Improvement of minimum 25% (GCE25) was achieved by 88.4% of patients, a minimum of 50% (GCE50) by 61.1%, a minimum of 75% (GCE75) by 25.6%, and a minimum of 90% (GCE90) by 4.6%. Patients previously treated with pulsed dye lasers had a significantly less response than those treated with other modalities (GCEmax 37.3% vs 61.8%, respectively).

CONCLUSION A large spot 532 nm laser is effective in previously treated patients with facial CM.
