Granulation Tissue and Healing Oral Wounds. Top Articles. What Is the Wound Healing Process? This healing process includes four main stages: Hemostasis. The first stage of healing stops the bleeding by forming a blood clot, also known as a thrombus.
Blood vessels constrict to restrict blood flow, and platelets stick together to seal the wound. Finally, threads of fibrin reinforce the seal through a process called coagulation. During the second stage, the injured blood vessels discharge a fluid that causes the wound to swell, and the repair process starts by removing damaged cells and bacteria. Inflammation helps stop further bleeding and ward off infection, and it only becomes problematic if prolonged or excessive.
In addition, a new network of blood vessels must be constructed so that the granulation tissue can be healthy and receive sufficient oxygen and nutrients. Myofibroblasts cause the wound to contract by gripping the wound edges and pulling them together using a mechanism similar to that of smooth muscle cells. In healthy stages of wound healing, granulation tissue is pink or red and uneven in texture.
Moreover, healthy granulation tissue does not bleed easily. Dark granulation tissue can be a sign of infection , ischemia, or poor perfusion. In the final phase of the proliferative stage of wound healing, epithelial cells resurface the injury. It is important to remember that epithelialization happens faster when wounds are kept moist and hydrated. Generally, when occlusive or semiocclusive dressings are applied within 48 hours after injury, they will maintain correct tissue humidity to optimize epithelialization.
Also called the remodeling stage of wound healing, the maturation phase is when collagen is remodeled from type III to type I and the wound fully closes. The cells that had been used to repair the wound but which are no longer needed are removed by apoptosis, or programmed cell death.
When collagen is laid down during the proliferative phase, it is disorganized and the wound is thick. During the maturation phase, collagen is aligned along tension lines and water is reabsorbed so the collagen fibers can lie closer together and cross-link.
Cross-linking of collagen reduces scar thickness and also makes the skin area of the wound stronger. Generally, remodeling begins about 21 days after an injury and can continue for a year or more. The stages of wound healing are a complex and fragile process. Failure to progress in the stages of wound healing can lead to chronic wounds.
Factors that lead up to chronic wounds are venous disease, infection, diabetes and metabolic deficiencies of the elderly. Challenges are nothing new for those of us who work in health care. Every day, we triumph over difficult situations. Yet, the current coronavirus outbreak has complicated even the simplest of procedures and has brought us additional challenges.

Wound Bed Preparation , Wound Care After assessing for and treating these factors, some other interventions that you may consider are: Cauterization of the hypertrophic tissue with silver nitrate. Treatment with a daily topical steroid cream for one to two weeks.
This can manage the overgrowth and allow for epithelial progression across the wound surface. Ensure that this cream is not used for more than 14 days because it can lead to excessive tissue atrophy. Utilization of a polyvinyl alcohol—gentian violet-methylene blue foam dressing.
This has shown to be an effective dressing to manage hypertrophic granulation tissue. You can help encourage the proliferation of granulation tissue by: Managing exudate Selecting dressings to provide a moist, warm healing environment Removing any necrotic tissue, which may cause MMPs to linger in excessive amounts Ensuring that the patient is properly nourished and hydrated Assessing and treating any underlying comorbidities Conclusion With these factors in mind, once you do start to observe granulation tissue formation, it is important to ensure that the wound is protected.
