What Is Acoustic Trauma?
Wound healing refers to the healing process after the body is exposed to external forces and the skin and other tissues are broken or damaged. The degree of damage and the ability of the tissue to regenerate determine the repair method, the healing time and the size of the scar. Both the whole body and local factors of the body can affect tissue regeneration and repair. Factors affecting regeneration and repair include systemic and local factors.

- 1. Age-related children and adolescents have strong tissue regeneration capacity and fast wound healing. In the elderly, on the contrary, the tissue regeneration is poor and the healing is slow. This has a lot to do with atherosclerosis and reduced blood supply in the elderly.
2. Nutritional serious protein deficiency, especially sulfur-containing amino acids (such as methionine,
- 1. Infection and foreign body infection can seriously affect the regeneration and repair methods and time. After a wound is infected, exudate increases and the pressure in the wound increases, often causing the wound to crack, or causing the infection to spread and aggravate the injury. Therefore, infected wounds should be drained as early as possible, and repair can only be performed after the infection is controlled. In addition, necrotic tissue and other foreign bodies also hinder healing and facilitate infection. Therefore, if the wound is infected, or there is more necrotic tissue and foreign body, it is often secondary healing. Clinically, for wounds with large wounds that have been contaminated by bacteria but have not yet undergone significant infection, debridement is performed to remove necrotic tissue, foreign bodies and bacteria, and to ensure that there is no infection, suture the broken tissue and repair the wound 2. Suture the wound to reduce the wound surface. In this way, the wound that should have been healed in the second stage can be shortened, and even the first stage healing can be achieved.
2. Good local blood circulation on the one hand ensures the oxygen and nutrition required for tissue regeneration, on the other hand, it also plays an important role in the absorption of necrotic substances and the control of local infection. Therefore, when the local blood supply is good, the wound heals well. Conversely, when there are atherosclerosis or varicose veins in the lower extremity blood vessels, the wound heals slowly. Local application of certain drugs or physical therapy has the effect of improving local blood circulation and promoting wound healing.
3 Complete innervation of nerve branches has a certain effect on the repair of injury. For example, ulcers caused by leprosy are not easy to heal because of nerve involvement. The damage of autonomic nerves causes disturbance of local blood circulation, and the effect on regeneration is more obvious.
4 Ionizing radiation can damage cells, damage blood vessels, and inhibit tissue regeneration. It also prevents scar formation. [1]
