Abstract

The endoscopic transnasal approach has become a procedure of choice for the surgical management of pituitary lesions. However, in conventional endoscopic transnasal surgery, the surgeon may become disorientated to the actual operating position. In our series, 31 patients have undergone an endoscopic transnasal approach to the pituitary lesions with the use of the navigation system InstaTrakTM for real-time imaging. This image guidance system proved valuable for anatomic localization during pituitary surgery. We have reduced the average surgical time, and improved patient outcome. As consequence, complications during surgery should decrease and safety should increase. Intraoperative image guidance is expected to have major advantageous effects on pituitary surgery by allowing the surgeon to remove pathology more efficiently. As this system is improved technically and surgeons become more proficient in its use, there should be better postoperative outcomes.
