In neurosurgery, we often encounter patients with cranial defects, either due to traffic accidents or craniotomy due to craniosynostosis, and no matter what the cause is, the impact of cranial defects is great and patients should pay attention to it. Because the cranial cavity is no longer intact after cranial defect, the brain tissue lacks external protective barrier, the intracranial pressure and intracranial environment will become very unstable, if not repaired, it will lead to a series of cranial defect syndrome, such as the patient will have dizziness and headache symptoms. Can I have skull repair surgery for dizziness and headache? Cranial repair surgery is recommended for patients with large cranial defects in order to rebuild a closed and complete cranial environment to ensure the safety of intracranial tissues and the normal functioning of brain nerves. However, it is important to choose good repair materials for skull repair surgery, which is a key factor affecting the success or failure of the surgery. Nowadays, titanium mesh material is widely used in many hospitals, but because it is a metal material and the overlay repair method used, there will be some problems and shortcomings after surgery, such as possible infection and rejection after surgery, patients will have cutting pain and sensitivity to the external hot and cold environment, etc.
