Skull fractures are more common in craniocerebral trauma, often caused by blunt violence or penetrating injury, and most of them do not require special treatment because the fracture itself is not important. However, the occurrence of skull fracture is closely related to the direction, size and deceleration distance of the violence. Skull fracture is often complicated by injuries to the brain, meninges, intracranial vessels and nerves, which can cause complications such as intracranial hematoma, cerebrospinal fluid leakage and intracranial infection. For its treatment: 1. A simple linear fracture of the closed skullcap does not require surgical treatment if there is no intracranial hematoma or other conditions. However, the occurrence of delayed intracranial hematoma should be observed and noted; for open linear fractures, if the fracture line is wide and there is a foreign body, the contaminated cranial bone can be removed after drilling and biting to prevent postoperative infection, and if there is intracranial hematoma, it should be treated as hematoma. 2.For depressed fracture, surgery should be performed. However, depressed fractures located in the venous sinus area should be considered as a contraindication to surgery to prevent massive bleeding caused by repositioning surgery. Closed depressed fractures can be treated by different methods according to the location, size, and presence of intracranial hematoma; open depressed fractures must be thoroughly debrided, repeatedly flushing the wound with saline, removing blood clots and foreign bodies, and removing inactive scalp, bone fragments, meninges and brain tissue. 3, skull base fracture in principle adopts non-surgical symptomatic treatment, skull fracture itself does not have special treatment, in order to prevent and control infection, antibiotics can be applied. In general, the diagnosis can be made according to the history of head trauma, clinical examination and X-ray examination, etc., and treatment is carried out according to the type of fracture.
