This article reports the surgical treatment of 47 cases of giant pituitary tumors in this article refers to the giant refers to the diameter of more than 4cm of the tumor.The tumor often infiltrates and penetrates the dura mater and the diaphragm, invades the cavernous sinus and spreads in the epidural growth and invasion before , In the posterior fossa, or into the amount of temporal lobe brain.In endocrine, 38 cases (80.8%) of non-secreting adenoma, 9 cases of growth hormone or prolactinoma.According to X-ray before surgery, CT scan of blood vessels or pneumo-angiography to determine the size of the tumor and its main part of the location of the operation can be transcranial and transabdominal sinus approach and the use of microsurgical techniques.The goal is to strive for complete removal of the capsule within the tumor so that the optic nerve And hypothalamic decompression, such as difficult to remove, you can subtotal or partial resection. After surgery are required to be treated with radiotherapy, the document discusses the indications for transsphenoidal and transurethral approach surgery.
