Role of Image Guided Navigation in Endoscopic Surgery of Paranasal Sinuses: A Comparative Study.

The aim of the current study is to share our experience with surgical outcomes of Functional Endoscopic Sinus Surgery using an image-guidance system. The study was a randomised control trial with the comparison between two groups. Image guidance system (Electromagnetic) was used for endoscopic surgery on patients with disease of the paranasal sinuses (n = 30). Results were compared with those in control patients who underwent similar surgery without image guidance during the same period (n = 30). The operating room time (image-guidance group, 165.68 ± 6.55 min [mean ± SE]; control group, 163.33 ± 5.43 min), Intraoperative anatomical localization was accurate to within 2 mm. Intraoperative blood loss (image-guidance group, 566.67 ± 62.23 ml [mean ± SE]; control group, 636.33 ± 72.59 mL) and complication rates (image-guidance group, 3.3%; control group, 3.3%) did not differ significantly between groups. We find image guidance system a useful tool with accuracy of 2 mm. Actual intraoperative time, blood loss and complications do not differ significantly with or without the use of IGS.
