Long-Term Patency of Maxillary Sinus Ostia Following Dilation with a Novel Osmotic Expansion Device: A Multi-Center Study of the Vent-Os® Sinus Dilation System

Please register to download the white paper


This white paper presents 12-month results from a multi-center prospective study on the patency of maxillary sinus ostia following dilation with a novel osmotic expansion device. The study was designed to evaluate basic usability and confirm expected safety and effectiveness of the Vent-Os Sinus Dilation System—developed by the SinuSys Corporation—when used to dilate maxillary sinus ostia in patients with CRS. Unlike balloon dilation devices that use rapid, high-pressure inflation, the Vent-Os Sinus Dilation System is a small, low-pressure, self-expanding insert designed to gently and gradually open the sinus ostia. These results were presented at the 2014 Annual Meeting of the  American Rhinologic Society.
