Cranial repair surgery is appropriate for most patients with cranial defects. However, not all patients are suitable for cranial repair surgery. The defect has to be larger than three centimeters or aesthetically disruptive. If either of the two conditions are met, both are suitable for surgery. However, before surgery, the patient should be evaluated by a specialized neurosurgeon to see if there are any contraindications to surgery. For example, there is no serious heart, brain, liver, kidney dysfunction, no serious coagulation disorders and serious mental disorders before surgery. Cranial bone repair surgery can solve the stability of the cranial cavity, protect the function of the brain tissue, improve the quality of life of the patient, and the surgical risk is low, which makes it a safer surgery in neurosurgery.
