Abstract
We have developed a superimposed image-guided surgery system which extends the conventional system by a function that enables three-dimensional instant and subjective recognition of the patient's nose and sinus cavities. Here, we report application of this system in stereo endoscopic sinus surgery. We have operated 5 cases of paranasal sinus cysts and 6 cases of chronic sinusitis with this system. We consider that the superimposed image-guided surgery system is useful and effective for more precise and safer manipulation.
