Balloon Sinuplasty is a breakthrough procedure that relieves the pain and pressure associated with chronic sinusitis. It is used by sinus surgeons to safely and effectively treat chronic sinusitis patients who are not responding well to medications such as antibiotics, nasal steroids, or over-the-counter (OTC) drugs and are seeking relief from uncomfortable sinusitis symptoms. Similar to how angioplasty uses balloons to open blocked arteries, balloon sinuplasty, a system of FDA‐approved, catheter‐based instruments, opens blocked sinuses. With balloon sinuplasty, a specially designed catheter is inserted into the nose to reach the inflamed sinus cavity. A small balloon is slowly inflated, deflated, and then removed. The process widens and restructures the walls of the sinus passage, helping to drain mucus from the blocked sinus and restore normal sinus drainage without cutting and with minimal bleeding.
