Hypophysectomy
Hypophysectomy (pronunciation: hi-pof-i-sek-to-mee) is a surgical procedure that involves the removal of the pituitary gland. The pituitary gland, also known as the hypophysis, is a small, pea-sized organ located at the base of the brain.
Etymology
The term "hypophysectomy" is derived from the Greek words "hypo" meaning under, "physe" meaning growth, and "ectomy" meaning removal.
Procedure
A hypophysectomy is typically performed to treat disorders of the pituitary gland, such as pituitary tumors. The procedure can be performed through the nose and sinuses (transsphenoidal hypophysectomy) or through an incision in the scalp and a hole in the skull (transcranial hypophysectomy).
Risks and Complications
Like any surgical procedure, a hypophysectomy carries certain risks and potential complications. These may include infection, bleeding, and damage to surrounding brain tissue. Because the pituitary gland plays a crucial role in regulating the body's hormones, removal of the gland can also lead to hormonal imbalances, requiring lifelong hormone replacement therapy.
