Next, the skull will be drilled, opened the lower occipital skull, under the transverse sinus and aspirated cerebrospinal fluid to deflate the brain. In case the patient has a tumor in the cerebellar hemisphere, the doctor will use a suction machine or an ultrasound knife to open the cerebellar cortex and dissect the tumor. If the patient has a tumor in the lobule, use an ultrasound knife to dissect around the tumor to control the source of bleeding. The last step is to stop bleeding and close the dura, fix the skull.
