A dent in the head does not heal on its own. This can only be a state of deformed healing, far from being the same as before, but for this aspect there is a need for specific treatment on a case-by-case basis. If the damage is so great that the fracture fragment compresses the brain tissue, causing obvious clinical symptoms, and the degree of concavity is greater than 1 cm in plane, it needs to be treated surgically and does not heal by itself. On the contrary, if there are no obvious clinical symptoms and the depression is less than 1 cm, it can heal by itself. The head is not particularly affected by the scalp and the external hair, so it is not a concern. If it does affect the appearance in some cases, the skull can be surgically repaired, which is relatively simple, without going into the substance of the brain, and is also a relatively aesthetic procedure.
