About the Operation

Transsphenoidal surgery is a procedure that allows the surgeon to remove tumours, cysts or other abnormalities that can affect the pituitary gland and the area around it. Your pituitary gland is a small, bean-shaped structure that lies at the base (bottom) of your brain behind your eyes and produces many different hormones (types of body chemicals) that are critical for survival.

Your surgeon will use an endoscope (a small tube-shaped tool) to see all of the important structures during the procedure. This technique was developed by surgeons at UHN. It is now the preferred way to remove tumours, cysts or other abnormalities from the area around your gland. Doing the surgery in this way can help you have a shorter stay in the hospital and a quicker recovery. Fortunately, most pituitary tumours are not cancerous.
