21. WOUND HEALING

22. 1. Inflammatory phase
2. Proliferative phase
3. Remodeling phase
NORMAL WOUND HEALING

23. PRIMARY INTENTION
• Occurs in uncontaminated wounds
with minimal tissue loss
• Heals by rapid epithelization and
minimal graduation tissue formation.
• Caused least inflammation and
leaves best scar
• Occurs in wounds with substantial
tissue loss, when edges cannot be
opposed.
• Wound is left open, and allowed to
heal by graduation, contraction and
epithelization.
• Takes long time and is accompanied
by a much more inflammatory
response and poor scar
SECONDARY INTENTION
WOUND CLOSURE AND HEALING
TERTIARY INTENTION
• Wound is closed several days
after its formation
• Results in a less satisfactory
scar than healing by primary
intention
