If the patient’s brain nerve is compressed, the treatment should be based on the nature of the compression, such as the patient’s cerebral hemorrhage resulting in nerve compression and limb inflexibility, etc. The treatment should be selected according to the amount of bleeding. If the amount of bleeding is relatively large, surgery should be done to remove the bruises and improve the patient’s symptoms. If the cerebral hemispheres are compressed because of brain tumors, such as pituitary tumors, the patient’s optic nerve will be compressed and the patient will have visual field defects. The treatment can only be done through surgery, but nowadays, the more mature surgery is minimally invasive surgery through the nose to remove pituitary tumors.
