How Balloon Sinuplasty Works<\/strong><\/h3>\n\n\n\nWith Balloon Sinuplasty, a specially-designed catheter is inserted into the nose to reach the blocked 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.<\/p>\n\n\n\n
