The Perfexion Gamma Knife is currently the most advanced Gamma Knife device for head tumor treatment. It is mainly suitable for small tumors and its strength is the treatment of multiple foci. The fifth generation of radio wave knife is the most advanced radio wave knife device in China at present. The radio wave knife has good therapeutic effect for both benign and malignant intracranial tumors of large size, and the radio wave knife has more experience in the application of fractionated treatment for large lesions compared to gamma knife. The intracranial tumors that can be treated with radio wave knife therapy include most of the benign and malignant intracranial tumors, but please visit a specialized doctor’s clinic for specific indications. The cost is related to the number of treatments. The radiofrequency knife is not a substitute for surgery. Many patients believe that the radiofrequency knife can completely replace surgery. This is a misconception. For some diseases, the radiofrequency knife has less risk and a better prognosis than surgery, but for many other tumors, the intracranial decompression achieved by surgery and the pathological diagnosis obtained cannot be matched by the radiofrequency knife. For some diseases, it is also recommended to perform a partial or major surgical resection to reduce the cranial pressure before treatment with the radiofrequency knife. Finally, the effectiveness of radiofrequency treatment depends on the tumor itself as well as the physician and physiatrist who designed the treatment plan. The prognosis after treatment varies depending on the nature of the tumor. Doctors and physiatrists specialize in different areas and have different understanding of the tumor. The difference in treatment philosophy and the requirement for treatment quality control dictate that different teams make plans that can have completely different timing and dosage.
