THE PITUITARY TUMOUR
The pituitary gland is
a tiny body about the size of a peanut situated at the center of the
skull with its stalk attached to the base of the brain. It produces
a number of hormones, which control other endocrine glands.
Sometimes a tumor of this gland can result in hormonal imbalance
with growth and other metabolic derangements. The neurosurgical
approach to this gland is fraught with difficulties owing to its
location and vision shadow areas, and also injury to cranial nerves
and other parts of the brain.

This gland can be very
easily approached through the nose under Endoscopic control, since
it is just a thin plate of bone away from the sphenoid sinus.
Sphenoid sinus is routinely opened during Endoscopic nasal surgery
to open the pituitary fosse through this sinus. Complete removal of
tumor is possible since there are no vision shadow areas in this
