For patients with brain tumors, there is sometimes confusion as to whether they should have traditional surgery or undergo Gamma Knife treatment. Traditional surgery (both open and minimally invasive) and Gamma Knife are two completely different types of treatment. In the former, the surgeon removes the tumor by hand; in the latter, the tumor is struck by gamma radiation. In terms of results, craniotomy is more straightforward because it removes the tumor; whereas the gamma knife does not remove the tumor immediately. In terms of damage, open traditional surgery will definitely cause trauma, while Gamma Knife may not cause bleeding. It can be said that each has its own advantages and disadvantages, and the choice will require very specialized judgment. One of the criteria for selection is whether the tumor is sensitive to Gamma Knife radiation? We do not recommend gamma knife treatment for gliomas because they are usually insensitive to gamma knife and should undergo craniotomy. On the contrary, for intracranial metastases, we often recommend gamma knife because, usually, metastases are more sensitive to gamma knife and can obtain good treatment results. For cavernous hemangioma, we do not recommend gamma knife treatment because there is no effect, unless it is cavernous hemangioma in the cavernous sinus to have effect. The second criterion for selection is the size and location of the tumor. In the case of meningiomas, for example, huge meningiomas (4CM or more) are always recommended to undergo conventional surgery. For smaller meningiomas that are in locations where the risk of surgery is too high, such as slope meningiomas, we sometimes recommend Gamma Knife surgery. In principle, since meningiomas are usually insensitive to Gamma Knife, Gamma Knife surgery is generally not an option if the risk of conventional surgery is not particularly high. Taking auditory neuroma as another example, gamma knife treatment can be considered for those smaller than 3 cm, but craniotomy is generally recommended for those larger than 3 cm. The third criterion for selection is the age and physical condition of the patient. For some elderly and frail patients, due to the weak ability to tolerate traditional surgery, we recommend appropriate relaxation of the indications for gamma knife surgery. For example, for a 75-year-old patient with a 3-cm auditory neuroma, we generally recommend gamma knife, but if the patient is 50 years old, we first recommend conventional surgery. It can be seen that the choice of craniotomy or gamma knife hand, according to the nature of the tumor, size, location, physical condition and age and other factors to determine. There are also some tumors that are not suitable for both craniotomy and gamma knife, for example, intracranial lymphoma is best treated with chemotherapy. At the same time, patients must break the misconception that Gamma Knife is risk-free when making their choice. Gamma knife rays can cause large areas of brain edema, can also damage important nerves around the lesion, and can even cause bleeding in the tissue around the lesion, which is not only risky, but sometimes very risky. In contrast, traditional surgery has become more and more refined through generations, and its treatment effect for brain tumors in many areas has almost reached perfection.
