Effet paradoxal du type d'excision sur la prise et le délai de cicatrisation des greffes expansées pour le traitement des brûlures aiguës: a propos de 1129 cas.

Split-thickness meshed skin graft is frequently used in the treatment of acute burns. We studied the effect of the type of basement preparation on graft intake and healing time. We retrospectively analysed 1,129 meshed grafts used in the treatment of acute burns between 1995 and 2005. Intake was significantly better after avulsion (82%) than after tangential excision (75%). Intake was better if avulsion was performed before day 7 (83% vs. 73%). A trend for better intake after tangential excision was seen when performed between day 7 and 21. Healing time was significantly shorter after tangential excision. These results show the paradox that avulsion favours graft intake but delays healing time, contrary to tangential excision.
