In the minds of the people, the faster a surgeon does surgery, the more skilled he is, so naturally the level is high. There is some truth to this, but judging the surgeon’s excellence by this is biased. There are several important criteria by which modern neurosurgery is judged. The first is functional preservation. The brain’s position in the human body is different from that of ordinary organs, and its function is particularly important. The weight of the brain accounts for only 3% of the body weight, but its blood flow accounts for 15% of the blood flow of the whole body, which fully illustrates the importance of brain function. The human brain has corresponding functional areas for speech, movement, hearing, vision, and even respiratory circulation. For example, damage to the posterior part of the inferior frontal gyrus in the frontal lobe of the brain may lead to motor aphasia (wanting to speak, but unable to do so), while damage to the precentral gyrus may lead to impaired movement of the contralateral hand and foot. Therefore, it is a priority for neurosurgeons to minimize the impact on these areas when performing brain tumor removal or hematoma removal. The rough and tumble approach of “tumor removed, arms and legs paralyzed” is not recommended. Secondly, the extent of resection of the mass. For benign tumors, theoretically, there should be no recurrence after total excision. For benign tumors that can be theoretically resected, neurosurgeons should try to pursue total resection. For malignant tumors such as glioma, the tumor should also be reduced as much as possible. Of course, factors such as age and physical condition should be taken into consideration. Thirdly, the size of trauma. The design of incision, the choice of access and pathway are related to the size of surgical trauma. Modern neuronavigation technology, the development of endoscopic technology has created new conditions for minimally invasive surgery. At present, the majority of pituitary tumors can be operated minimally invasively via the nose. With the guidance of neuronavigation technology, surgical incisions are more precise and can be made smaller than ever before. The fourth, speed. A skilled neurosurgeon who completes a procedure in a relatively short period of time can reduce the chance of infection and the amount of anesthetic drugs used by the surgical patient. In short, a neurosurgeon facing a procedure will consider the extent of resection, functional protection, and the size of trauma in a comprehensive manner in order to develop a surgical strategy and to complete the procedure as quickly as possible within a certain time frame based on proficiency to obtain the best possible result.
