Study of navigation assisted functional endoscopic sinus surgery
Introduction: Endoscopic sinus surgery(ESS) is the first choice of surgery to treat medicine-refractory sinonasal disease. However, when a single lens system is used to perform ESS, the 2-dimensional imaging results in a loss of depth of field. To lessen complications and operate with greater precision, frameless stereotaxic integration of computed tomography(CT) has been used during functional endoscopic sinus surgery(FESS) for intraoperative real time localization.
