It is a general consensus in the neurosurgical community that larger skull defects require prompt cranial repair, and it should also be common knowledge to the majority of patients. It is human nature to have a cranial repair, and it should also be a common understanding that the neurosurgeon should strive to achieve the maximum possible return to the previous state of the defect. PEEK repair of the skull is an embedded repair. Using 3D reconstruction 3D printing technology, the PEEK material is the exact same shape and size as the bone window, and can be precisely embedded in the bone window with a tight fit, with the edges of the PEEK material dovetailing precisely and smoothly with the edges of the bone window. Even if you touch the seam directly, it will feel very smooth, and the human scalp also has a certain thickness, generally the thickness of the human scalp to the skull is about a centimeter, so peek repair of the skull, through the scalp, hands generally can not feel the seam at the joint, should not feel anything, very smooth. In addition, PEEK has excellent performance in all other aspects, including stiffness, rigidity, elasticity, stability, thermal insulation, histocompatibility, plasticity, radioactive transmission, magnetic compatibility, etc., which is comparable to that of autologous cranial bone, and is particularly effective in clinical applications. Our team also continuously carries out technical improvement and material optimization design, and introduces the concept of aesthetic plastic surgery, so as to carry out PEEK cranial bone repair in an integrated manner and achieve ideal cranial bone repair results. Patients with cranial defects are recommended to go to regular hospitals to repair their skull as soon as possible to regain their health.
