Head smash injuries can take several forms: i. scalp injury; ii. primary cranial injury; and iii. secondary injury. Scalp injuries mainly include scalp hematoma, scalp swelling, scalp contusions, and scalp lacerations. Scalp hematoma and scalp swelling can be applied cold in the early stage within 24 hours, and hot compresses can be applied after 48 hours, with attention to rest. If the hematoma is under high tension, fluid extraction and pressure bandaging will be performed at a later stage, and if this is not effective, surgical incision and drainage will be performed. If there is a scalp laceration, scalp debridement suturing is performed. Primary craniosynostosis manifests as neurological reactive symptoms such as dizziness and nausea, then concussion, brainstem injury, and diffuse axonal injury. With concussion as well as neurological symptomatic reactions, it is important to rest and most patients recover on their own. Patients with brainstem injury and diffuse axonal injury are more severely ill and often have a poorer prognosis. Then there is the skull fracture, which can be conservatively or surgically repaired depending on the fracture, to prevent the occurrence of secondary intracranial hematoma or cerebral contusion. There is also a case of secondary cranial injury, secondary cranial injury mainly includes intracranial hematoma and cerebral contusion, according to the size of the hematoma and contusion, the patient’s general condition, the decision for conservative or surgical treatment.
