The human brain tissue is actually very fragile and can be easily damaged by the outside world if not protected by the hard shell of the skull. However, in neurosurgery, cranial defects are very common, and when they occur, the brain tissue is at risk, and the impact can be imagined. First of all, after cranial defect, the patient’s scalp will have obvious collapse or scalp expansion, which has a great impact on the appearance, and the patient will suffer from psychological shock, and in the long run, the patient will have low self-esteem and depression; secondly, after cranial defect, if the head is hit by external sharp objects, the brain tissue will be injured, and it will be life-threatening; thirdly, after cranial defect, the complete closure of the cranial cavity is destroyed The intracranial environment and intracranial pressure will be very unstable, thus affecting the cerebrospinal fluid circulation and blood circulation, and affecting the brain nerve function, resulting in a series of craniosynostosis syndromes. What are the manifestations of craniosynostosis syndrome? The specific manifestations of craniosynostosis syndrome are that the patient will often feel dizzy and headache, numbness and weakness of limbs, become very depressed and irritable, and the patient will also have some mental disorders, some effects on vision, hearing and smell, and in more serious cases, there will be seizures. The damage that a skull defect can cause is unpredictable, and it is important to go to the hospital in time for skull repair surgery. Without being modest, our team is currently better at performing skull repair surgery using a new PEEK material, which has excellent performance in all areas, making up for the shortcomings of traditional materials and achieving excellent clinical results. Moreover, we have incorporated the concept of aesthetic plastic surgery into the surgery, and the patient’s head shape looks better after the surgery.
