How to differentiate and diagnose scalp avulsion?

Scalp laceration is a specialized skin, which contains a large number of hair follicles, sweat glands and sebaceous glands. It is easy to hide dirt, bacteria and infection. However, scalp blood circulation is very rich, although the scalp laceration, as long as the timely implementation of thorough debridement, infection is rare.

When the scalp laceration is shallow and the cap aponeurosis is not injured, the laceration is not easy to open, the broken end of the blood vessel is difficult to shrink and stop bleeding, and the bleeding is more. If the cap aponeurosis is broken, the wound is obviously split, and the broken end of the injured blood vessel shrinks and self coagulates with the wound, so there is less bleeding.

Scalp avulsion is a kind of serious scalp injury, almost all of which are caused by women with braids accidentally involving their hair into the rotating wheel. Because the epidermis layer, subcutaneous tissue layer and cap aponeurosis layer are closely connected, under the strong pull, the scalp is often avulsed from the cap aponeurosis space, sometimes with part of the periosteum, so that the skull is exposed.
