Advanced Laser Therapies for Vascular Lesions: Port-Wine Stains & Rosacea

The presentation discusses advanced laser therapies for vascular lesions, focusing on port-wine stains and rosacea, led by Dr. Aria Vizarnia, a laser expert. Dr. Vizarnia begins by outlining the basic principles of vascular lasers, highlighting the absorption properties of hemoglobin across different wavelengths. He explains which lasers are typically used in practice, emphasizing the importance of selecting appropriate parameters based on lesion size, type, and chromophore presence. He describes effective treatment protocols, particularly for port-wine stains, noting that early treatment, ideally within six months of age, yields better outcomes due to thinner skin and higher levels of fetal hemoglobin. The use of pulsed dye lasers is identified as the gold standard for treating these lesions, with particular attention given to proper settings and safety precautions when treating pediatric patients.



Transitioning to rosacea, Dr. Vizarnia references studies comparing the efficacy of pulsed dye lasers and Intense Pulsed Light (IPL), noting that while both treatments can be effective, his preference leans towards pulsed dye for better results. He shares insights from studies that illustrate improvements in symptoms like erythema and flushing, with different pain and swelling responses observed between the treatment modalities. In closing, he emphasizes targeting individual telangiectasias before addressing background erythema and encourages attendees to pose questions for further clarification.
