Skull Base and Pituitary Tumor Program

The Skull Base and Pituitary Program at Hoag is Orange County’s only comprehensive, multidisciplinary program for pituitary tumors. Offering a wide range of specialists—including neurosurgeons; ear, nose & throat surgeons; endocrinologists; ophthalmologists; radiologists and pathologists—the program provides a level of comprehensive care that is unsurpassed in our community.

The main gland of the endocrine system, the pituitary gland is considered the “master” gland because the hormones it produces control other glands as well as many body functions, including growth. The pituitary includes the anterior and posterior pituitary.

The anterior pituitary affects growth, metabolism, electrolytes, blood pressure, skin pigmentation, thyroid function and sexual development, fertility and lactation. The posterior pituitary secretes oxytocin, a hormone that increases uterine contractions and antidiuretic hormone (ADH), which increases reabsorption of water by the kidney.
