  11. 11. I. Healing by First Intention  In healing by first intention the sutured wound heals without infection or separation at the edges. There are minimal granulation tissues present and thus a small scar ensures. The clean surgical wounds are healed by this process.  When wounds heal by first intension healing, granulation tissue is not visible and scar formation is minimal.
  12. 12. II. Healing by Second Intention (Healing by Granulation)  In this type the edges of the wound are not approximated. As a result large amount of granulation tissue is formed to fill up the gap in the wound. The resulting scar tends to be large. Contaminated and infected wounds are healed by this method. Any wound, in which there is extensive tissue loss, wound healing takes longer period. III. Healing by third intention  In this there is a combination of healing by primary and secondary intention. Either the wound is initially left open and later approximated or initially sutured and later break open and the healing occur by filling in by granulation tissue. It is used for deep wounds.
