Liver injury is the most common type of organ damage in cases of abdominal trauma. The livers size and location in the body makes injury relatively common compared to other abdominal organs, and blunt trauma injury to the liver is typically treated with nonoperative management. Liver injuries are rarely serious, though most injuries to the liver are concomitant with other injuries, particularly to the spleen, ribs, pelvis, or spinal cord. The liver is also susceptible to toxic injury, with overdose of paracetamol being a common cause of liver failure. Face
Facial trauma may affect the eyes, nose, ears, or mouth. Nasal trauma is a common injury and the most common type of facial injury. Oral injuries are typically caused by traffic accidents or alcohol-related violence, though falls are a more common cause in young children. The primary concerns regarding oral injuries are that the airway is clear and that there are no concurrent injuries to other parts of the head or neck. Oral injuries may occur in the soft tissue of the face, the hard tissue of the mandible, or as dental trauma.The ear is susceptible to trauma in head injuries due to its prominent location and exposed structure. Ear injuries may be internal or external. Injuries of the external ear are typically lacerations of the cartilage or the formation of a hematoma. Injuries of the middle and internal ear may include a perforated eardrum or trauma caused by extreme pressure changes. The ear is also highly sensitive to blast injury.
The effects of burns vary depending on the depth and size. Superficial or first-degree burns only affect the epidermis, causing pain for a short period of time. Superficial partial-thickness burns cause weeping blisters and require dressing. Deep partial-thickness burns are dry and less painful due to the burning away of the skin and require surgery. Full-thickness or third-degree burns affect the entire dermis and is susceptible to infection. Fourth-degree burns reach deep tissues such as muscles and bones, causing loss of the affected area.Thermal burns are the most common type of burn, caused by contact with excessive heat, including contact with flame, contact with hot surfaces, or scalding burns caused by contact with hot water or steam. Frostbite is a type of burn caused by contact with excessive cold, causing cellular injury and deep tissue damage through the crystallization of water in the tissue. Friction burns are caused by friction with external objects, resulting in a burn and abrasion. Radiation burns are caused by exposure to ionizing radiation. Most radiation burns are sunburns caused by ultraviolet radiation or high exposure to radiation through medical treatments such as repeated radiography or radiation therapy.Electrical burns are caused by contact with electricity as it enters and passes through the body. They are often deeper than other burns, affecting lower tissues as electricity penetrates the skin, and the full extent of electrical burns are often obscured. They will also cause extensive destruction of tissue at the entry and exit points.
