Advancing Precision in Functional Endoscopic Sinus Surgery: The Role of Navigation Technology

Objectives: Navigation technology is a useful tool for surgeons performing complex rhinologic procedures, such as extensive sinonasal polyposis (SNP), revision surgeries, anatomical variations, and cerebrospinal fluid leaks. This study aimed to evaluate the role of navigation systems in functional endoscopic sinus surgery (FESS). Materials and Methods: Sixty patients from KKR ENT Hospital, Chennai, were divided into Group A (FESS with navigation) and Group B (FESS without navigation). Patients with chronic rhinosinusitis (CRS) with SNP, revision surgeries for SNP or sinonasal tumors (SNT), and frontal sinus disease (FSD) were included. Pre- and postoperative Lund-Mackay scores, Sino-Nasal Outcome Test-22 (SNOT-22) scores, and CT scans were analyzed. Navigation assistance using the Fusion Compact Medtronic System was employed based on surgical evaluation. Postoperative nasal endoscopy and follow-ups assessed outcomes. Results: No significant differences in SNOT-22 and endoscopic scores were observed between groups. However, intraoperative complications and recurrence were higher in Group B, indicating better outcomes in Group A. Navigation significantly improved precision and reduced complications (p < 0.05). Conclusion: Navigation technology enhances surgical accuracy and reduces complications, offering significant benefits in complex FESS cases.
