The skull is a very hard piece of the human skeleton, but it is not indestructible. Some people in our life have severe defects in the skull due to heavy blows from external forces. The cranial defect will affect the aesthetic image, and at the same time, the patient’s intracranial tissues lack the protection of the cranial bone and are easily attacked by the outside world. In view of all these, once the skull defect occurs, it is necessary to do skull repair surgery in time to avoid bigger problems. In addition, patients with cranial defects often feel dizzy and have headaches, and are afraid of loud noises and vibrations. Some patients may have difficulty concentrating, memory loss, or even have few words and depression. Therefore, cranial repair surgery should not be delayed. What is cranial defect repair surgery? In fact, skull repair surgery is a very routine surgery, and with the progress of medical technology, this surgery is becoming more and more perfect and mature, as long as you choose a regular professional hospital to do the surgery, you do not have to worry too much about the safety risk. Of course, in addition to choosing a regular hospital for skull repair surgery, the more important thing is the material of skull repair surgery. At present, the new polyether ether ketone peek material, this material is comparable to the human skull, with great elasticity, stability and heat insulation, the focus is to be able to shape the skull in three dimensions according to the patient’s head, highly restore the skull structure, and there is no adverse reaction after surgery. We not only use advanced peek materials, but also continuously improve the technology and optimize the design, and also introduce the concept of cosmetic plastic surgery, upgrading to PEEK cranial repair plastic surgery, which can achieve the triple effect of anatomical integrity, functional perfection and aesthetic appearance, and is highly praised by patients. It is recommended that patients with cranial defects go to regular hospitals to take appropriate materials for repair as soon as possible to regain their health.
