Balloon sinuplasty
Balloon sinuplasty is a procedure that ear, nose and throat surgeons may use for the treatment of blocked sinuses. Patients diagnosed with sinusitis but not responding to medications may be candidates for sinus surgery. Balloon technology was initially cleared by the U.S. Food and Drug Administration〔http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfPMN/pmn.cfm〕 in 2005 and is an endoscopic, catheter-based system for chronic sinusitis. It uses a balloon over a wire catheter to dilate sinus passageways. The balloon is inflated with the goal of dilating the sinus openings, widening the walls of the sinus passageway and restoring normal drainage.
== Overview ==
Sinus surgery with balloons may be performed in a hospital, outpatient surgery setting or in the physician’s office under local anesthesia. The physician inserts a guide catheter through the nostril and near the sinus opening under endoscopic visualization. A flexible guide wire is then introduced into the targeted sinus to confirm access. Most guide wires have a light on the tip which may produce light transmission seen through the skin to help the physician with correct placement of the guide wire. Once access to a blocked sinus is confirmed, a balloon catheter is advanced over the guide wire and positioned in the blocked sinus opening for inflation. The balloon is inflated. If the procedure is successful, the sinus will remain open after the balloon is deflated and removed as the bone surrounding the sinus is permanently remodeled.
