Balloon sinus dilation involves the use of catheter-based devices to dilate sinus ostia with the goal of improving the ventilation and drainage of diseased sinuses in the treatment of a variety of inflammatory sinus disease pathologies. Although increasingly popular, there remains debate regarding the efficacy of this technique in the setting of an expanding body of literature. Furthermore, there is increasing concern regarding the potential over use of this technology. Consequently, the American Academy of Otolaryngology issued a Consensus Statement on Balloon Sinus Dilation in 2017 to ensure patient safety and proper utilization. This mini-seminar will engage attendees in an evidence-based discussion regarding the indications, contraindications, and outcomes for balloon sinus dilation in the operating room and office setting. Attendees will enhance their understanding of the primary findings, conclusions, and limitations of the scientific literature as it relates to balloon sinus dilation, and as viewed from the perspectives of the panel members. Attendees will gain insight into the controversy surrounding potential overuse and abuse of balloon sinus dilation. Attendees will also gain practical knowledge pertaining to the successful use of balloon sinus dilation, as well as possible complications directly related to the use of this technology. The panelists are experts in advanced Rhinology from both academic and private practice environments, and all have significant experience, and varied views, on balloon sinus dilation.
