We would report our experience and arrangement on using neurosurgical navigation system to the endoscopic sinus surgery (ESS). The case is 34-year-old woman who has bilateral and multiple postoperative maxillary cysts. The ESS was performed under the guidance of navigation system, StealthStation TRIA, but it has been installed software only for neurosurgery. One of problems like the point that the monitor CT image becomes right and left was improved by using the mirror. Another problem like the head setting with three point pin was improved by the head band fixation.
It might be impossible and also generates cost according to the equipment for installing software for otolaryngology. It was thought that it was possible to correspond for the otolaryngological surgery by some technical arrangements.
