If repair is a very ancient surgical procedure that has been in development for thousands of years in human history. After a long period of development and progress, cranial repair has become a very mature and routine procedure in the modern medical environment. Many people often end up with cranial defects because of trauma or because of craniotomy for their own craniosynostosis. After cranial repair, these patients may also need to undergo review of CT, MRI and other medical examinations, so they are more concerned about whether there is any effect on brain CT after cranial repair. For this question, the effect of skull repair on brain CT is mainly related to the use of skull repair materials. If metal materials are used, then the metal materials may interfere with the projection of radiation and the operation of the magnetic field, so it will have an impact on the CT MRI and other medical examinations, and the image results of the examination will have metal artifacts that interfere with the doctor’s judgment. For example, the titanium mesh restoration material, which is more widely used in clinical practice, has this defect. In addition, titanium mesh is a material that has many defects and shortcomings in addition to affecting ct MRI. For example, postoperative infection may occur rejection, the material will wear the scalp, resulting in scalp breakage, material exposed; this metal material is not insulated, the patient may be sensitive to the external hot and cold environment after surgery discomfort; titanium mesh this material, hardness is not high, easy to be deformed by external forces, resulting in scalp collapse; in addition titanium mesh material shaping effect is too good … …so titanium mesh is not a very ideal material for cranial repair. At present, there is a more advanced polyether ether ketone peek material, which has achieved good results in clinical practice. Polyether ether ketone peek material is a new type of special polymer material, and its various properties are very close to human autologous cranial bone. This polymer material will not affect the radiation and magnetic field, and will not affect the ct nuclear magnetic and other medical examinations. Moreover, it can well overcome the above-mentioned problems that may arise from titanium mesh material and become a new trend of cranial bone repair material. At present, our team is using this advanced polyether ether ketone peek material extensively, and the team also keeps improving and innovating the technology and optimizing the design of the material, and also innovatively introduces the concept of cosmetic plastic surgery, while completing the anatomical repositioning of the skull, the various factors affecting the appearance of the cosmetic plastic treatment, to achieve the organic unity of anatomical integrity, functional perfection and aesthetic appearance, and achieve good clinical results. The clinical results are excellent.
