Balloon Sinuplasty is a breakthrough procedure that relieves the pain and pressure associated with chronic sinusitis. It is used by 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 and painful sinusitis symptoms. Similar to how angioplasty uses balloons to open blocked arteries, Balloon Sinuplasty, a system of FDA‐cleared, catheter‐based instruments, opens blocked sinuses. The procedure is less invasive than traditional sinus surgery. It allows most patients to return to normal activities quickly. With Balloon Sinuplasty, a specially‐designed catheter is inserted into the nose to reach the inflamed sinus cavity. A small balloon is slowly inflated, which 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. This approach also preserves the natural structure of the sinuses. Published clinical data shows that Balloon Sinuplasty provides symptom relief for the majority of patients.
