Surgery for pituitary tumors
The main treatment for many pituitary tumors is surgery. How well the surgery works depends on the type of tumor, its exact location, its size, and whether it has spread into nearby structures.
Transsphenoidal surgery: This is the most common way to remove pituitary tumors. Transsphenoidal means that the surgery is done through the sphenoid sinus, a hollow space in the skull behind the nasal passages and below the brain. The back wall of the sinus covers the pituitary gland.
For this approach, the neurosurgeon makes a small incision along the nasal septum (the cartilage between the 2 sides of the nose) or under the upper lip (above the upper teeth). To reach the pituitary, the surgeon opens the bony walls of the sphenoid sinus with small surgical chisels, drills, or other instruments depending on the thickness of the bone and sinus. …continue here – American Cancer Society detailed guide to pituitary surgery
On 21st May, I had surgery at the Prince of Wales Hospital here in Randwick for the
removal of the pituitary tumour. Dr Kwok performed the surgery.
“Dr Kwok is one of the most senior neurosurgeons in Sydney. He has maintained a high profile in all facets of neurosurgery, especially surgery for pituitary tumors.
As a pioneer in neuroendoscopy, he has taught many of the Australian and Southeast Asian neurosurgeons currently practicing this technique.
Dr. Kwok has appointments at all three on-campus hospitals and is a strong advocate of medical student and registrar training.”
