Basics
Forms of wound healing:
Doctors distinguish between different forms of wound healing:
- Primary wound healing: this type of wound healing occurs, for example, in the case of cuts, as well as wounds after surgery caused by the scalpel. Among doctors, this type of wound healing is called by the Latin term "Sanatio per primam intentionem", with the abbreviation "wound healing p.p." being common. This is understood to mean that the wound heals without complications and only a fine scar remains after a few days.
- Secondary wound healing: We speak of secondary wound healing when the wound edges diverge. This can either be the case in advance or when the wound has become infected. In this case, the term "per secundam intentionem" (p.s.) is used. In order to close such a wound, the defect in the tissue must first be filled with so-called granulation tissue. In the further course, new skin can then develop over the wound. Secondary wound healing usually takes more time than primary wound healing and leaves a more noticeable scar with a less smooth surface. In some cases, there may also be functional impairment of the affected area of the body.
- Epithelial wound healing: In this form of wound healing, only the top layer of skin (epidermis) is injured. Thus, the wound can heal within a few days. A scar usually does not remain. In this case, it is called epithelial wound healing.
The healing process:
If the wound healing is not completed within four weeks, one can assume a chronic wound. If such a wound healing disorder is present, the cause should be found out by a doctor.
