The pituitary gland controls most of the hormones in the body. Tumors of this gland can damage the body by over-producing hormones. As the tumor grows, it can also damage the patient's vision by pressing on the optic nerves.
Unless it is very small and produces no hormones itself, a pituitary adenoma needs to be surgically removed. The operation is performed without incisions on the face or head, through the nasal sinus. Dr. Jean uses a high-tech endoscope, so that this operation can be done with minimal damage to the sinuses, allowing for easy recovery and quicker return to work and life.
