What is Abnormal wound healing

Wound healing process can be differentiated by two types which are Normal Wound Healing and Abnormal Wound Healing, Basically wound is refers to breach in normal tissue continuity resulting in a variety of cellular and molecular sequelae.

Abnormal wound healing is divided into three intentions which are

  • Wound healing by Primary Intention
  • Wound healing by Secondary Intention
  • Wound healing by Third Intention

Wound healing by Primary Intention

Wound healing by Primary Intention is also refers as first intention, it occurs in the clean incised wound or surgical wound. Wound edges are approximated with sutures. It also occurs with immediate closure of a wound using sutures, clips, staples and adhesive materials that favor healing with minimal scarring.
In abnormal wound healing there is more epithelial production than fibrosis and scar will be liner, smooth and supple or bending easily.

Wound healing by Secondary Intention

Wound healing by Secondary Intention occurs in wound with extensive soft tissue loss like major trauma, burns and wound with sepsis. It also occurs in the wound that is left open and allowed to heal by granulation tissue, contraction and epithelialization.

Wound healing by Third Intention

Wound healing by Third Intention is delayed closure of a wound after a variable period of time for which it has left open. It is applied to wounds that are grossly contaminated or present late, but do not have significant tissue loss.
The surgeon aim is to convert untidy to tidy by removing all contaminated and devitalized tissue.
