Intralesional cryotherapy for hypertrophic scars and keloids: a review

Abstract

Lay SummaryThere are many different types of treatment for hypertrophic scars and keloid scars, but no treatment works perfectly in all individuals. Intralesional cryotherapy is a relatively new technique which freezes a scar from the centre outwards. This article provides a summary of the technique and the evidence for its usefulness in the medical literature. While no large-scale studies have been reported, the findings from small scale studies have been very encouraging. Intralesional cryotherapy appears to be safe and effective, with few adverse effects, but more research is needed in order to compare it adequately with other types of treatment
