Analysis of therapeutical effects of Er:YAG and CO_2 laser post treatments of small hemangiomas

摘要

The main goal of our study was the evaluation of treatment efficiency of two types of ablative laser-CO_2 and Er:YAG (or ERB) treatment. 183 patients (Er:YAG-105 patients, CO_2-78 patients) were analyzed to compare the curative effects and adverse events, such as loss of pigment and appearance of scars caused by these two lasers. The results of the study showed the slightly better effectiveness of Er:YAG laser radiation in comparison with CO_2 laser in the case of treatment of small hemangiomas up to 3 mm in diameter. In the Er:YAG laser application the curative effect was in 99%, hypo-pigmentation occurred in 18%, and scars in 70% of all treatments. In the CO_2 laser application the curative effect was in 97%, hypo-pigmentation in 52%, and scars in 77% from all treatments.
