Balloon Sinus Dilation (BSD) is a surgical procedure used to treat sinusitis and other related problems through minimally invasive techniques. This involves inserting a thin endoscope into the nose without disrupting the surrounding bone and tissue. A small balloon is then gently inflated to widen blocked passageways and allow for proper drainage of sinus fluid. Balloon dilation of sinus openings is a relatively new technique for performing sinus surgery. Our ENT surgeons are trained and selectively use the specialized balloon sinus technique.
