Assessing Feasibility and Safety of Using Ultrasonic Bone Aspirator for Revision Endoscopic Sinus Surgery

Abstract

Background and Objectives: This study introduced and evaluated the efficacy of an ultrasonic bony aspirator (UBA) in revision endoscopic sinus surgery and compared the outcomes to those of the traditional cold instrument approach.Methods: This retrospective study enrolled 57 patients who underwent revision endoscopic sinus surgery between June 2010 and December 2017, 17 patients with a UBA approach and 40 patients with traditional instruments.Results: Median Lund–Kennedy scores showed a statistically significant difference between the two groups at 3 months (p=0.004). Synechiae occurred in 17.6% and 35% of cases in the UBA and traditional groups, respectively. The mean operative time was significantly shorter in the traditional group (p=0.001).Conclusion: The use of a UBA in revision endoscopic sinus surgery was safe and effective.
