The skull is a very important tissue in the human body, which plays a very important protective and supportive role for the brain and head and face organs, and maintains the health of the human body and the operation of the whole organism. Therefore, if a skull defect occurs, it will bring great harm and requires timely cranial repair surgery. Some patients ask how traumatic cranial defect repair helps in brain recovery. Traumatic cranial defects are most often seen in accidental craniocerebral trauma, such as car accident injuries, injuries from workplace safety accidents, accidental falls, falling objects, fights, and so on. These situations often occur more serious craniocerebral trauma, not only the skull may be damaged, but also the intracranial brain tissue may suffer damage, resulting in a series of craniosynostosis syndrome. Therefore, cranial bone repair surgery should be performed in a timely manner after the acute phase of treatment leaves behind a cranial bone defect. This type of traumatic cranial defect repair can be very helpful for brain recovery. Our team then performs cranial bone repair extensively. The team applies the current very advanced, excellent performance of polyether ether ketone peek material, and constantly improve and upgrade the technology and optimize the design of the material, in order to improve the protective performance, improve the comfort, maintain the activity of the tissues, prevent the temporal muscle atrophy, prevent the scalp abrasion and so on to make great progress, and the team also innovatively introduces the concept of cosmetic plastic surgery, cosmetic treatment of factors affecting the appearance of the aesthetics of the appearance, can achieve anatomical integrity, functional perfection, and can help to restore the brain, and can also help to restore the brain. The organic unity of anatomical integrity, functional perfection and aesthetic appearance can be achieved, and excellent results have been achieved.
