There are a very large number of approaches to brain surgery, which must be viewed specifically according to the particular condition at the time. For the most common hypertensive cerebral hemorrhage, the practice is actually relatively simple and uniform, usually after general anesthesia is satisfied, the head is tilted to the side, and then the skin is incised along the lateral hairline, separating the skin as well as the subcutaneous soft tissues and muscles so that the skull can be seen, and then the cranial drills are applied to drill the incisions, which are basically three to four holes. The cranial flap is then removed in its entirety with a milling cutter, and the dura mater is visualized, hemostatized, and draped. After opening the dura mater, the brain hemorrhage is aspirated by following the corresponding sulcus and gyrus into the brain hemorrhage and the bleeding vessel is electrocoagulated. At a later stage, a bone flap is placed and reinforced with a bone graft, and the skin and surrounding tissues are sutured again, essentially ending the operation. Otherwise speaking, brain surgery is all-encompassing and must be judged on the basis of the situation at the time, with each procedure being different.
