Currently, the treatment technology for pituitary tumors is relatively mature. For early-stage pituitary microadenomas that are only a few millimeters in size, and where vision and visual fields are not yet affected, a definite diagnosis can be made. Under the surgical microscope, complete removal surgery is achievable, and it is possible to preserve the normal function of the pituitary gland. As surgical experience continues to increase, not only can tumors within the sella be removed, but even large adenomas or giant pituitary adenomas growing above the sella can be safely excised. Therefore, for patients with pituitary tumors, it is advisable to choose to visit a local hospital as early as possible and opt for a complete removal of the pituitary tumor through a transnasal transsphenoidal approach.
