Cranial bone plays an important role in human health, but nowadays cranial defect is a common disease, such as traffic accidents, falling objects, etc. may cause cranial defect. With a piece of intact skull missing, the cranial tissues have no protective barrier and can be dangerous at any time. Can I get sunlight without skull repair and does it affect my brain? If skull defect is not treated in time, of course, it will affect the brain, because when the skull defect is damaged, the closed nature of the cranial cavity is destroyed, the intracranial pressure and intracranial environment will become unstable, which will cause cerebrospinal fluid circulation disorder and blood circulation disorder, and then affect the patient’s neurological function, causing a number of complications, the specific performance can be headache and dizziness, mental inattention and limb weakness, etc. Can I get sunlight after skull defect? This is mainly because titanium mesh is a metal material with fast thermal conductivity and poor heat insulation, and if the sun is shining for a long time, the patient’s scalp may have obvious burning sensation. As you can see, it is still important to choose the right material for skull repair surgery. In view of some shortcomings of titanium mesh material, our team used a new type of PEEK material to carry out the surgery, which well compensates for the shortcomings of titanium mesh material, and will not be sensitive to external heat and cold after surgery, which is the ideal material for cranial bone repair surgery at present. In addition, we have successfully introduced the concept of aesthetic plastic surgery, and carried out comprehensive PEEK cranioplasty, the postoperative results are very natural and beautiful, helping patients to regain self-confidence.
