Surgery is not needed for the time being, but follow-up observation can be carried out, and most patients can repair themselves. It's not too late to have surgery after epilepsy and other symptoms. The baby's skull is soft, which can produce a ping-pong depression and can't see the fracture line. Generally, the depth of depressed fracture is less than 1cm, and there is no dural laceration, which is called simple depressed fracture. There is no need for emergency surgery after injury, and those who need surgical reduction can be implemented after the condition is stable. Almost all patients over 2cm have dural laceration, often accompanied by vascular and brain tissue damage, which is called complex depressed fracture, which can cause brain dysfunction, hematoma and epilepsy and needs surgical treatment. Therefore, the operative indication of skull depressed fracture is: 1, and the depression depth is above 1cm; 2. The fracture piece pierces the dura mater, causing hematoma and brain injury; 3. Depression fracture compression causes hemiplegia, aphasia and epilepsy; 4. Being on the forehead and face affects the appearance. Zhou Yan, Department of Neurosurgery, Air Force General Hospital
