Injury mechanisms such as falls, assaults, sports injuries, and vehicle crashes are common causes of facial trauma in children [6] [4] as well as adults. [7] Blunt assaults, blows from fists or objects, are a common cause of facial injury. [8] [1] Facial trauma can also result from wartime injuries such as gunshots and blasts.
Abrasions on elbow and lower arm. The elbow wound will produce a permanent scar. A first-degree abrasion involves only epidermal injury. A second-degree abrasion involves the epidermis as well as the dermis and may bleed slightly. A third-degree abrasion involves damage to the subcutaneous layer and the skin and is often called an avulsion.
Dermabrasion is a mechanical surgical skin planing method which has remained popular partially because it may afford an overall lower cost and may provide similar or superior results as newer laser methods for certain skin conditions.
In a major injury, if epithelial cell migration and tissue contraction cannot cover the wound, suturing the edges of the injured skin together, or even replacement of lost skin with skin grafts, may be required to restore the skin. As epithelial cells continue to migrate around the scab, the dermis is repaired by the activity of stem cells.
A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. [1] [2] Wounds can either be the sudden result of direct trauma (mechanical, thermal, chemical), or can develop slowly over time due to underlying disease processes such as diabetes mellitus, venous/arterial insufficiency, or immunologic disease.

Most injuries to the skin are minor and do not require specialist treatment. Lacerations of the skin are typically repaired with sutures, staples, or adhesives. The skin is susceptible to burns, and burns to the skin often cause blistering. Abrasive trauma scrapes or rubs off the skin, and severe abrasions require skin grafting to repair. Skin ...
Traumatic lesions can be superficial abrasions that heal on their own or deep, large lacerations that need to be sutured. [6] Often, "friction burns" occur, especially on the face. The unfolding airbag can cause multiple superficial parallel lesions with its slapping action. [7] [8]
Wound healing refers to a living organism's replacement of destroyed or damaged tissue by newly produced tissue. [1] In undamaged skin, the epidermis (surface, epithelial layer) and dermis (deeper, connective layer) form a protective barrier against the external environment. When the barrier is broken, a regulated sequence of biochemical events ...
