Navigation system (navigation) for endoscopic sinus surgery (ESS) is useful to avoid complication of orbit, optic nerve or the base of skull. The navigation was used in 6% (111/1842) between September 2004 and July 2015. There were 61 men and 50 women with a mean age of 55 years old (16-84). ESS was performed on all patients under general anesthesia, and extranasal surgery was additionally performed on nine patients.
The disease consisted of chronic rhinosinusitis (CRS, n=40), paranasal cysts (n=39), sinonasal tumors (n=19), fibrous dysplasia (n=4), thyroid gland ophthalmopathy (n=4), paranasal fungal diseases (n=2), idiopathic cerebrospinal fluid rhinorrhea (n=2), optic canal fracture (n=1). Frontal sinus was the most lesion to require the navigation (n=56). As reasons using the navigation in patients with CRS, there were pansinusitis (n=31), postoperative stage (n=21), and lesions adjacent to orbit or skull base (n=8).
Using the navigation for ESS, we could safely perform on all patients without any complications during surgery. Use of the navigation is thought to be more indicated.
