If there are no symptoms such as dizziness, nausea, vomiting, weakness of limbs or seizures, it generally proves that there is no pressure on the brain tissue and no special treatment is needed. However, if the skull depression is caused by head injury, a depression of more than 0.5cm is indicated for surgery. A traumatic skull depression of more than 0.5cm proves to be more or less compressive to the local brain tissue. In serious cases, it may lead to dizziness, headache, weakness of limbs, or sequelae of recurrent seizures, which must be given after surgical incision to reset the skull and put back the skull to suture the wound in order to solve the fundamental problem and avoid the appearance of sequelae.
