Table 1 Criteria for histologic scoring of wound healing
Score | Re-epithelialization | Wound margins distance | Granulation tissue | Vascularization |
|---|---|---|---|---|
0 | <25% of re-epithelialization | Distant wound margins | Absent granulation | Presence of haemorrhage |
1 | 25-50% of re-epithelialization | Distant wound margins by granulation tissue | <30% of granulation tissue | Presence of haemorrhage and capillaries |
2 | 50-75% of re-epithelialization | Moderate distance between wound margins | Granulation in 30-60% of wound bed | Presence of many capillaries |
3 | >75% of re-epithelialization | Reduced distance between wound margins | >60% of granulation tissue | Presence of few capillaries |
4 | Complete re-epithelialization | Closed wound margins | Traces of granulation with presence of mature collagen fibres | No evident vascularization |
