The choice of treatment for functional pituitary tumors must be made on a case-by-case basis. If the pituitary tumor is of the prolactin type, it can be treated by oral medication, usually mainly oral bromocriptine, which can reduce the secretion of prolactin and in some cases can even achieve clinical cure without the need for open surgery. However, if there is no significant improvement after more than 6 months of oral medication, the lactogenic pituitary tumor needs to be treated by surgical intervention. There are two main types of surgical procedures: 1) the relatively classical craniotomy for pituitary tumors, and 2) the transnasal removal of pituitary tumors. At present, more than 95% of pituitary tumors are removed through the nose by endoscopic means. Unless the pituitary tumor is particularly large and produces significant clinical symptoms, it is treated by open-heart surgery. Transnasal pituitary tumor removal is a relatively simple procedure with no wound on the outside, just a wound inside the nasal cavity, and is minimally invasive. After the surgery, it is staged accordingly, depending on the specific type of pathology. If it is benign, only a review is needed at a later stage; if it is malignant, further treatment by radiotherapy is required.
