| Research Abstract |
We developed stereo navigation system for safer and more precise endoscopic sinus surgery. The usage of the system is as follows. At first, CT image of the patient is analyzed before a surgery. Then the sinuses and surrounding important structures such as skull base or optic nerve are segmented respectively to make 3-D organ models.
At the time of surgery, when we insert stereo endoscope in a nose, 3-D organ models are superimposed on an endoscopic monitor with a perspective view. In comparison with the conventional endoscopic surgery, the anatomy behind the surgical field becomes visible.
