Transnasal surgery is a type of surgery in which an endoscope and/or surgical instruments are inserted into part of the brain by going through the nose and the sphenoid bone (a butterfly-shaped bone at the base of the skull) into the sphenoidal sinus cavity.

Transsphenoidal surgery is used to remove tumors of the pituitary gland. (Such tumours, although within the skull, are outside the brain itself).

TRANSSPHENOIDAL SURGERY FOR PITUITARY TUMORS

With transsphenoidal surgery, surgeons approach the pituitary gland through the nose and sphenoid sinus — transsphenoidal means “through the sphenoid sinus.”

Using a microscope or an endoscope, they can navigate through these passages and remove the tumor through the nose without needing to make an incision in face or drill through the skull.

Transsphenoidal surgery can be extended into the brain cavity to treat very selective tumors.

Moreover can be done both with microscopic and endoscopic magnification devices in order to reach the best inspection of the anatomical structures.
