Craniosynostosis is a common clinical condition that can be caused by a variety of factors, such as craniocerebral trauma or craniocerebral diseases that require debridement and decompression surgeries, which can leave a craniosynostosis behind. Now that a cranial defect has occurred, it is important for the patient to treat it aggressively and to minimize the damage as much as possible. Moreover, patients should understand that cranial defects usually cannot grow well on their own, and local collapse and deformation will also occur in a long time, which not only seriously affects the appearance, but also has a great impact on the health of the organism. Therefore, it is recommended that patients with cranial defects of more than 3cm should undergo cranial bone repair surgery about 3 months after the surgery, so as to better restore the integrity of the skull and ensure that all intracranial life activities can operate normally. Are there risks associated with cranial repair surgery? Many uninformed patients are worried about the risk of surgery, but in fact, in neurosurgery, cranial repair surgery is a routine surgery, has been developed for thousands of years, the safety is still very high, so patients do not need to worry too much, but you need to go to the regular hospital to let the experienced doctors to arrange the surgery. Moreover, before the skull repair surgery, the choice of repair material is also very important, which is related to how the effect will be after the surgery. At present, titanium mesh material is widely used in many local hospitals. Although titanium mesh material has made some progress than before, there are still some problems, such as the high chance of infected wear and tear, the patient’s sensitivity to the external hot and cold environments after the operation, and even the possibility of the material being exposed, etc. We use polyetheretherketone as our repair material. And we use polyether ether ketone peek material is very good to make up for these problems, this is a new type of polymer material, it is in the stability, hardness, elasticity, thermal insulation and histocompatibility and other aspects of the performance is very good, the clinical treatment effect is remarkable, has helped a lot of patients to solve the problem, it is to do the ideal material for craniofacial repair.
