Recently, there have been frequent inquiries from patients about scalp hematoma, so I will use the rest time to organize it for you in the hope that it will be helpful to you. Scalp hematoma is generally divided into three kinds of subcutaneous hematoma, subcapsular tendon hematoma and subperiosteal hematoma: 1. Subcutaneous hematoma: generally the area under stress is small, the hematoma is not large in scope, the pressure pain is positive, and sometimes there is a sense of depression when touched. 2, subcapsular hematoma: the area under stress is larger, the hematoma is very soft, positive fluctuating sensation, and no obvious boundary. 3, subperiosteal hematoma: often accompanied by a fracture of the skull Sometimes these three hematomas occur in a mixture. Treatment: In the early stage of injury (within 24-48 hours), local cold compresses can be applied. If the hematoma has not absorbed on its own after a week, the accumulated blood can be withdrawn and pressure bandages can be applied to allow local tissue adhesions to heal. If the hematoma repeatedly increases in size, it is necessary to consider whether it is caused by the rupture of a larger artery, which requires judgment by a competent physician and further treatment.
