Input (English): Question: Do vascular patterns in mature hypertrophic burn scars treated with fractional CO2 laser?
Answer: Mature hypertrophic burn scars treated with a fractional CO2 laser showed a statistically significant increase in vascular density in the superficial dermis. A non-statistical decrease in clinically perceived erythema and improvement of overall appearance was seen. To our knowledge, this is the first report of increased vascular density in burn scars treated with fractional CO2 laser and suggests our prior assumptions on causes of erythema in mature hypertrophic scars may need to be challenged.
Output (English): yes
