Intralesional laser therapy treatment for hemangiomas: technical evolution.

The authors have treated over 500 consecutive pediatric patients with voluminous hemangiomas (thickness of over 10 mm), since 1996. They were all treated with intralesional laser therapy using the potassium, titanyl, phosphate (KTP) laser. Since the initiation of KTP laser therapy for deep hemangiomas in 1996, the authors have significantly modified their treatment regimen. Changes from our original treatment protocol include lower power settings, and decreased treatment intervals. Additionally, we are now simultaneously treating the deep component, using intralesional KTP laser, and the superficial component using a pulsed dye laser. Fibrosis associated with intralesional therapy has been greatly decreased by injecting small amounts of dilute steroid solution during treatment of the deep component. While maintaining the efficacy of the procedure, we have been able to greatly decrease complications associated with it. The authors detail their current techniques as well as the evolution and rationale for modifying the original treatment regimen.
