Tumour removed through patient's nose

Warning: this video shows a surgical operation taking place

This video shows surgeons at the Queen Elizabeth Hospital in Birmingham removing a tumour through a patient's nose using a 3D endoscope for the first time in Europe.

During the operation surgeons and theatre staff all wore special 3D glasses so they could follow the procedure on screen.

The surgery was carried out on a patient with a rare condition called Acromegaly, where the pituitary gland near the brain produces too much growth hormone.

Without the surgery she would have had to live with symptoms like headaches, joint pains, sweating and snoring, or have radiotherapy.
