Trans-sphenoid operation is done to insert surgical instruments through your nose into the brain to remove pituitary tumour. The transspehnoidal surgery uses an endoscope which is done through the sphenoid sinus into the hollow space of your skull, just below the brain. It is at the back wall of the sinus that covers the pituitary gland.

It should be noted that not all types of tumours require radiation therapy. This is because all pituitary glands are not cancerous and so if a part of the gland is left, it does not grow back. Transsphenoidal surgery is performed by a team of surgeons, including neurosurgeons and ENT (ear, nose, throat) surgeons.

The pituitary gland is quite important since it controls the function of other endocrine glands. This gland has two parts – the anterior and the posterior lobe. The hypothalamus transmits signals to the pituitary that inhibit pituitary hormone production. However, you should not be afraid of a pituitary tumour because most of them are benign.
