Everyone wants to live a peaceful and disease-free life, but sudden accidents always come to us without any preparation, posing a great threat to our health and normal life. Cranial defects are one of the most common types of accidents, in which a part of the skull is missing and becomes collapsed and incomplete. In such cases, cranial repair surgery undoubtedly opens a brand new door for the patient. According to a survey, many patients with cranial defects experience various discomforts after surgery, such as dizziness and scalp tightness. What is the matter with scalp tightness after cranial repair? Scalp tightness after cranial repair may be caused by soft tissue swelling, or increased scalp tension, in general, the problem is not very big, patients do not need to worry too much, go to the regular hospital in time to do a detailed examination, and then symptomatic treatment, will soon be able to get well. In addition, there are some patients who choose to perform titanium mesh cranial repair surgery, due to the poor thermal insulation properties of the material, there will be a headache and dizziness in hot and cold environments after the operation; there is also titanium mesh tissue compatibility is not very good, it may be possible to occur in the rejection reaction or postoperative infections, and even the scalp tissue destruction, resulting in the titanium mesh exposed. In recent years, the appearance and application of a new material peek, prompted the skull repair surgery to achieve the desired repair effect, which is undoubtedly a major progress in medicine. peek material has many advantages, it is histocompatible, basically will not occur after surgery complications. It has high hardness, strong impact resistance, and is not easy to deform even if it is bumped after surgery. Its shape is also more ideal than previous clinical materials, and the symmetry between the two sides after surgery is high. A few years ago, our team introduced peek as a cranial bone repair implant material and carried out peek cranioplasty, which not only restores the skull as it was before, but also has a certain aesthetic effect on the shape. At the same time, we added the concept of aesthetic plastic surgery, formulated personalized repair and plastic surgery plan, and paid attention to the improvement of details, such as the design of the material aperture thickness, the design of the material edges, the separation of the various layers of tissues during the operation reset protection, prevention of temporal muscle atrophy, prevention of scalp abrasion, aesthetic plastic surgery, etc. A lot of improvements were made, and the overall aesthetic effect can be greatly improved.
