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. Material and Methods: The present hospital based observational, analytical study was undertaken with 30 patients to evaluate outcome, intraoperative time, intraoperative blood loss and intraoperative complications of navigation assisted functional endoscopic sinus surgery in the Dept. of ENT, at our tertiary care centre. Conclusion: Computer aided ESS is one of the best teaching tool for surgeons , it minimizes intraoperative complications by accurate identification of critical landmarks, ensures complete removal of disease which results in successful outcome of surgery.
