This endoscopic procedure is used to remove a tumor near the pituitary gland located behind the nose.  This procedure is preformed jointly with a neurosurgeon and ENT surgeon.

The ENT surgeon enlarges a passageway in the back of the nasal cavity. An endoscope and surgical tools are placed in an open space behind the nose called the sphenoid sinus.  A portion of the wall of the sphenoid sinus is removed to expose the dura.  The dura is then cut open to expose the tumor.  The tumor is carefully scooped away and removed in pieces, leaving the pituitary gland intact.  The nostrils are packed with gauze.
