For patients with severe cerebral hemorrhage, some require craniotomy for treatment. The craniotomy treatment requires debridement and decompression if combined with high intracranial pressure, which will lead to cranial defect situation after surgery, which will lead to incomplete whole skull, which will not only affect the aesthetics, but also have a series of cranial defect syndrome in serious cases, so it is necessary to perform repair surgery. So, what is the best material to repair the skull after brain hemorrhage? It is very necessary to repair the skull after brain hemorrhage, if the skull defect is serious, not only may cause damage to the intracranial tissues due to external collision, but also may injure the brain nerve in serious cases, so a very positive and effective method is to perform skull repair surgery. In the past, the repair surgery was performed with plexiglass, bone cement, etc., and also came to widely use titanium mesh material. Although the cost of these materials is not high, the performance of some aspects is not too perfect, so the corresponding problems are prone to occur after surgery, so it is necessary to be more cautious when choosing. At present, from the clinical aspect, the more ideal material to do the skull repair surgery after brain hemorrhage is peek material. This is a very advanced polymer material, which is more stable and has good histocompatibility, and can be consistent with the human skull, and the postoperative recovery is more ideal. This advanced polyetheretherketone PEEK cranial repair material is widely used here, and we continue to improve and upgrade the technology and material optimization design, and the introduction of the concept of aesthetic plastic surgery, in this area has accumulated a wealth of clinical experience, to obtain better repair results. It is recommended to choose peek material to repair the skull after cerebral hemorrhage, which is not only aesthetic after surgery, but also can effectively avoid a series of postoperative problems and make patients and their families feel more satisfied.
