Treatment of Pituitary Disorders

NS Home

The pituitary gland secretes a number of hormones that control many of the endocrine functions of the body. It secretes prolactin, which stimulates mild production after pregnancy; ACTH (adrenocorticotrophic hormone) controls cortisol production by the adrenal glands; TSH (thyroid stimulating hormone) stimulates the thyroid gland to produce thyroid hormones; GH (growth hormone) is important for normal growth and bone development and for maintaining bone and muscle mass in adults.

Pituitary tumors can be either secretory (secreting excessive pituitary hormones) or non-functioning (non-secreting). Large tumors, whether secretory or non-functioning, can cause visual loss from pressure on the optic nerves or chiasm, headaches and/or hormone deficiencies from damage to the normal pituitary gland.

There are a number of syndromes associated with excess hormone secretion, including:
  • Acromegaly
  • Cushing's Disease
  • Prolactinoma
  • TSH Adenomas

There are also a number of tumors, cysts and other disorders in the pituitary gland area that do not secrete hormones but may need to be treated. These include:
  • Non-functioning pituitary adenomas
  • Pituitary cysts (Rathke cleft cysts, arachnoid cysts)
  • Craniopharyngiomas
  • Inflammatory disorders (sarcoid, lymphocytic hypophysitis and others)

Prolactinomas (excess prolactin secretion) can cause amenorrhea (loss of menstrual periods) and galactorrhea (breast milk production) in women, and low testosterone in men with loss of libido (sex drive) and erectile dysfunction. First line of treatment is usually medication.

Minimally Invasive Surgery

NS Home

When surgery is necessary, most pituitary tumors can be removed through a transsphenoidal approach. A small incision is made in the back of the nasal passage, into the patient's sphenoid sinus. The pituitary gland sits in a bony cavity called the "sella turcica" in the back wall of the sphenoid sinus. This minimally invasive technique, called transsphenoidal surgery, typically helps patient recover from surgery faster.

Our surgeons, specializing in minimally invasive transsphenoidal surgery, perform more than 150 transsphenoidal procedures per year.
