A modification of the Hynes procedure--a surgical innovation in the treatment of mature hypertrophic scars in children.

In 1957, Hynes first described the shaving and grafting procedure for the treatment of mature hypertrophic scars (HTSs). This procedure involved excision of mature HTS using a scalpel blade followed by split-skin grafting (SSG). We have modified this technique through the novel application of Versajet™ (Smith & Nephew, Hull, UK) for the sub-total excision of mature HTS with SSG.
