Generally, for patients with pituitary tumors, it is usually recommended to choose endonasal transsphenoidal minimally invasive surgery to completely remove the pituitary tumor. If no unexpected circumstances occur during the surgery, the process typically takes about two hours, though this can vary depending on the size of the tumor and how smoothly the surgery proceeds. Patients are given general anesthesia before the surgery, which involves inducing anesthesia and ensuring it is administered successfully. After the surgery, patients are moved to a recovery room to recuperate for a period of time. Once the patient gradually regains consciousness, the tracheal tube is removed, and they are returned to their hospital room. Therefore, the total time involved is approximately three to four hours.
