Cranial repair surgery is a routine procedure that is frequently required in neurosurgery. This surgery is also very old and classic. Cranial bone repair surgery techniques are becoming more and more mature, and repair materials have followed the progress of updates, from the initial fleece and metal pieces, to later plexiglass, bone cement, silicone, etc., and then to the current commonly used titanium mesh and polyether ether ketone PEEK materials, along the way, the material performance is getting better and better, and the repair effect is getting more and more ideal. Currently, polyetheretherketone PEEK material is a cranial repair material with very good performance and relatively better results, which is favored by neurosurgeons and patients with cranial defects. When it comes to repair surgery, it is inevitable that many patients will be concerned about the cost of treatment. Although the cost of PEEK is relatively high, it is well worth the cost because of its excellent performance and good postoperative results. Our team uses the new PEEK material, which is currently very advanced, and we continue to improve and upgrade the technology and optimize the design of the material, and introduce the concept of aesthetic plastic surgery, while carrying out the PEEK cranioplasty, which has achieved outstanding results in clinical practice, achieving anatomical integrity, functional perfection, and aesthetic appearance of the unity, and is highly praised by patients.
