Transsphenoidal surgery This is the most common way to remove pituitary tumors. Transsphenoidal means that the surgery is done through the sphenoid sinus, a hollow space in the skull behind the nasal passages and below the brain.

The back wall of the sinus covers the pituitary gland. Hypophysectomy is a surgery performed in people, dogs and cats for the treatment of clinical pituitary tumors and other masses within the region of the pituitary gland.

The surgical approach in people is through the nose using a cannula and endoscope for visualization. The pituitary gland may be affected by a wide variety of systemic disorders.

The pituitary could be directly involved by the same processes that affect other organs (e.g., inflammatory, autoimmune, or infectious disorders), or the primary disease process may elicit indirect, distant effects on pituitary–hypothalamic hormonal function. Surgery to remove a pituitary tumor is typically performed by a neurosurgeon, a surgeon specializing in the treatment of disorders of the central nervous system, which includes the brain and spine.

In some cases, an ENT (ear, nose, and throat) surgeon may be the surgeon or part of the team performing the surgery. Transsphenoidal surgery is the most common type of surgery used to treat pituitary gland tumours.

It is done under general anesthetic (you will be asleep). The surgeon uses surgical tools to get to the tumour through the nose and the sphenoid sinus (transsphenoidal). This surgery may be used to remove some or all of a pituitary gland tumour.

The pituitary gland releases too much adrenocorticotropic hormone in people with this condition. This can lead to easy bruising, high blood pressure, weakness, and weight gain. The pituitary gland's location (above the inside of your nose) makes it challenging to access. In most cases, we use the endoscopic endonasal transsphenoidal approach.

Hyponatremia after pituitary surgery is presumed to be due to antidiuresis; however, detailed prospective investigations of water balance that would define its pathophysiology and true incidence have not been established. In this prospective study, the authors documented water balance in patients fo.

Published on Barrow Neurological Institute Neurosurgeon Andrew S. Little, MD, demonstrates the process of removing a tumor of the pituitary gland using minimally-invasive endoscopic. The pituitary gland may be affected by a wide variety of systemic disorders. In some instances, the pituitary is directly involved by the same processes that also afflict other organs, while in other disorders, the primary disease process has indirect, distant effects on pituitary function.
