There are many causes of craniosynostosis in life. For example, trauma, brain disease, intracranial decompression, etc. can all lead to cranial defects. Once the cranial defect, the location of the defect will lose the protection of the soft tissues inside the skull by the cranial bone, which will bring threat to the life and health of the patient. Therefore, patients with cranial defects should have cranial bone repair surgery in time to better protect their lives and health. Do I need to review after skull repair? Cranial repair surgery is a mature surgery in neurosurgery, but of course any surgery has risks. Cranial repair surgery is crucial for material selection to avoid rejection reactions, such as titanium mesh. PEEk is a new material that is resistant to compression, smashing, and high temperatures, and does not interfere with MRI at all. skull repair made of PEEK (polyether ether ketone) material can completely recreate the patient’s original curvature, including the face, and zygomatic arch to achieve a perfect tight fit. skull repair made of PEEK material is very safe, and the success rate of the surgery reaches a high level, due to the precise 3D reconstruction technique. The bone plate is seamlessly embedded in the defective bone window and blends in with the autologous cranial bone. Do I need to be reviewed after skull repair? In our neurosurgery department, patients who have undergone cranial bone repair with PEEk material have been found to have overcome the metallic artifacts of the PEEK (polyether ether ketone) bone plate during the MRI process.
