Can I still do airplane after skull repair? If it is just repaired, it is not recommended to take a plane, it will lead to intracranial pressure changes during takeoff or landing, if it is fully recovered, there should be no large skull loss after skull repair, no skull loss in the airflow changes when the plane crosses the air layer should not stimulate the brain tissue, generally speaking, it will not cause any impact. Even if the skull repair surgery is done, no matter it is high speed rail or airplane, it is possible to pass the security check, which patients can still be assured. Moreover, skull repair surgery not only gives patients an aesthetic effect, but also reduces the harm caused by skull defects. Therefore, the cranial defect surgery is beneficial but not harmful. The choice of skull repair material: polyetheretherketone material is mostly used in clinical practice. This is because the histocompatibility of polyetheretherketone and the human body have a very good integration. Patients basically do not have rejection reactions. It is also more comfortable and has a stronger thickness. It is similar to the human skull. Especially for pediatric patients, it can better adapt to the growth and development of human autogenous cranial bone. And it will have a lower infection and rejection rate. The most important point is that patients do not have to worry about how the surgery will affect the shape. If the repair is done with polyetheretherketone material, the 3D data can be extracted precisely to create a personalized repair material that matches the structure of the patient’s bone window. What are the benefits of the surgery for the patient: The hard skull repair material can effectively prevent the brain from being impacted by external forces. Cranial bone repair also helps to improve problems such as impaired blood supply to the brain and abnormal cerebrospinal fluid circulation. The longer the cranial defect, the higher the incidence of cranial defect syndrome and secondary brain damage. Moreover, craniosynostosis also leads to a change in the shape of the cranial defect area, and the scalp is affected by atmospheric pressure, which makes it invaginate and compress the brain tissue. Therefore, in order to restore the cranial cavity confinement, maintain the physiological intracranial pressure stability and alleviate the cranial defect syndrome. After cranial defect, the skull should be repaired as early as possible to avoid the above symptoms, which threaten the health of patients. The material is no different from normal after cranial bone repair. After the operation, attention should be paid to the administration of antibiotics to prevent infection, hemostasis and neurotrophic drug treatment; attention should be paid to the observation of the changes of the patient’s surgical cavity drainage, regular drug changes and observation of incision healing.
