Our UHN programs and services are among the most advanced in the world. We have grouped our physicians, staff, services and resources into 10 medical programs to meet the needs of our patients and help us make the most of our resources.
University Health Network is a health care and medical research organization in Toronto, Ontario, Canada. The scope of research and complexity of cases at UHN has made us a national and international source for discovery, education and patient care.
Our 10 medical programs are spread across eight hospital sites – Princess Margaret, Toronto General, Toronto Rehab’s five sites, Toronto Western – as well as our education programs through the Michener Institute of Education at UHN. Learn more about the services, programs and amenities offered at each location.

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.
