Why do I need a cranial debridement when I have a brain hemorrhage? When a patient has a sudden cerebral hemorrhage, if first aid is not administered in time, cerebral edema may develop and in severe cases, life-threatening conditions may occur. At this time, in order to provide first aid, the patient will be debridement decompression surgery, which can play a role in reducing intracranial pressure and stop more danger. In fact, in addition to cerebral hemorrhage can cause cranial defects, today’s society, a variety of accidents, disasters, and a variety of cranio-cerebral surgery, may cause cranial defects, cranial defects often bring some physical and psychological problems to the patient. Impact of cranial defects on patients: According to the survey, after cranial defects, on the one hand, the patients’ appearance and image are seriously damaged, resulting in low self-esteem. On the other hand, without the protection of the skull, patients have to be careful in everything, especially insecure. In addition, the brain tissue is prone to secondary damage, which may cause cerebrospinal fluid circulation abnormalities, blood supply disorders and other problems. It can be seen that cranial defects will bring great influence to the normal life of patients. Most of the patients will actively seek materials and hospitals to repair the cranial defect, which is very worthy of promotion. It is generally recommended that patients go to regular hospitals for cranial bone repair surgery in a timely manner when the diameter of the defect is larger than 3 centimeters after 2-3 months of bone flap surgery. Treatment: Cranial repair surgery is a neurosurgery for cranial defects with a medical material to remedy a routine surgery, the purpose is to repair the defective area, restore the integrity of the skull, and improve the patient’s self-confidence. Secondly, it increases patient safety and promotes the recovery of neurological function. The specific effect of cranial repair surgery, mainly by the repair material to determine, such as titanium mesh, patients in the repair, may occur rejection or infection, may also cause deformation and collapse, material exposure, it is obvious that this repair material has many shortcomings, and is not suitable for patients to repair. The peek cranioplasty, which is formed by using peek as implant material and adding plastic concepts, effectively avoids many phenomena caused by titanium mesh cover repair, and the postoperative appearance is natural and beautiful.
