Tumor in the ptero-saddle region of the brain is a relatively serious matter, because once the tumor tissue is formed, it will produce certain pressure on the brain, and then malignant ones will also cause a series of erosion of the surrounding tissues, which will cause headache, nausea, vomiting, and other symptoms, and the erosion of the other normal brain tissues will result in a certain degree of dysfunction. For the pterygoid region, the surrounding adjacent tissues are relatively complex, down there is the pituitary gland, up there is the optic cross, bilateral internal carotid arteries on both sides, so any damage to any place may cause serious abnormalities, for example, compression of the pituitary gland may cause endocrine dysfunction. For example, if the pituitary gland is compressed, it may cause endocrine dysfunction. If the optic cross is compressed, it may cause visual impairment; if the internal carotid arteries are compressed bilaterally, it may cause insufficient blood supply to the brain, and cerebral infarction may occur. Therefore, tumors in the pterygoid region are relatively serious, and if found and treated in time, the prognosis is still good.
