Reconstruction of tissues refers to the process of repairing or regenerating damaged or lost tissues in the body. This can occur naturally through the body's healing mechanisms or be facilitated through medical interventions. Techniques may include surgical procedures, tissue engineering, and the use of biomaterials to support tissue growth. In medicine, reconstruction is often necessary after injuries, surgeries, or diseases that affect the skin, muscles, or organs. Advances in fields like stem cell therapy and regenerative medicine are enhancing the ability to restore function and appearance, improving the quality of life for patients undergoing such treatments.
