Transsphenoidal Pituitary Tumor Resection

Transsphenoidal Pituitary Tumor Resection

Transsphenoidal pituitary tumor resection is the surgical removal of a tumor located on the pituitary gland. The pituitary gland is a pea-sized gland located in the base of the skull, behind the bridge of the nose. It controls important functions in the body, including the production of chemicals that regulate certain body functions (hormones).

Pituitary tumors are rarely cancerous, and many can be treated with medicines. However, a tumor may need to be removed if it causes overproduction of certain hormones that cannot be controlled with medicine. A tumor may also be removed if it presses on nearby structures. During a transsphenoidal pituitary tumor resection, the tumor is accessed and removed through the nose and the hollow area behind the nose (sphenoid sinus). MRIs may be used to help guide the procedure.

Tell a health care provider about:

  • Any allergies you have.
  • All medicines you are taking, including vitamins, herbs, eye drops, creams, and over-the-counter medicines.
  • Any problems you or family members have had with anesthetic medicines.
  • Any blood disorders you have.
  • Any surgeries you have had.
  • Any medical conditions you have.
  • Whether you are pregnant or may be pregnant.

What are the risks?

Generally, this is a safe procedure. However, problems may occur, including:

  • Infection.
  • Bleeding or a blood clot.
  • Allergic reactions to medicines or dyes.
  • Damage to other structures or organs, such as surrounding brain tissue.
  • Scarring

The following complications are possible but rare:

  • Leakage of cerebrospinal fluid.
