The brain is an important organ, and the skull, as a barrier to protect the brain, is of paramount importance. But accidents are unpredictable, and a sudden traffic accident leads to a serious cranial defect and depression, so the patient is facing a greater safety hazard, so we can’t be careless. First of all, the skull defect depression down, the head occurred a serious deformation, face beauty greatly reduced, the patient’s psychological will also become very low self-esteem, long-term depression will arise. Secondly, if the skull is depressed, the brain tissue will be easily damaged if it is accidentally knocked and touched, which will be more dangerous. Thirdly, the long-term depression of the skull will press on the brain tissue and bring more discomfort to the body. What are the symptoms of depressed skull compressing brain tissue? Once the depressed skull presses on the brain tissue, the patient will experience headache and dizziness, nausea and vomiting. If the area of depression is large, it will lead to a gradual increase in intracranial pressure and even coma, which will affect life safety. And if the depression is deeper, it can lead to brain damage, causing epilepsy, hemiplegia, and various symptoms such as aphasia and blurred vision in patients. Cranial depression is such a serious matter that patients should pay attention to it, and it is especially crucial to go to the hospital for skull repair surgery in time. However, it is important to pay attention to the choice of materials for skull repair surgery. Many local hospitals commonly use titanium mesh material, which is not expensive, but has many post-operative problems and is not recommended. The PEEK material we currently use is different. It is a very safe polymer material with excellent performance in all aspects, so there is no need to worry about the various problems that can occur with titanium mesh materials. At the same time, we have introduced the concept of cosmetic surgery in the surgery, which really highly restores the skull structure and is more natural and beautiful.
