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 traumatic cranial defect repair is very helpful for brain recovery. In an academic paper published in the Chinese Journal of Neurosurgery in 2016, “Chinese Expert Consensus on Traumatic Cranial Defect Plasty”, it is pointed out that cranioplasty (also known as cranial repair surgery) can not only repair cranial defects, restore the patient’s cranial appearance and protect the function, but also effectively restore normal cerebrospinal fluid dynamics and cerebral cortical perfusion, which is conducive to the reduction of intracranial complications, and helps the patient’s Neurological function recovery. This is how we are currently carrying out extensive cranial defect molding. The team applies polyetheretherketone peek material, which is very advanced and has excellent performance, and constantly improves and upgrades the technology and optimizes the design of the material, so as to make great progress in improving the protective performance, improving the comfort, maintaining the activity of the tissues, preventing the temporal muscle from atrophy, and preventing the wear and tear of the scalp, etc. Moreover, the team innovatively introduces the concept of cosmetic plastic surgery, and carries out aestheticization of the factors affecting the appearance of the body, thus comprehensively carrying out the peek cranioplasty. Thus, the comprehensive peek cranial repair plastic surgery can achieve the organic unity of anatomical integrity, functional perfection and aesthetic appearance, and achieve excellent results.
