Balloon Sinuplasty Balloon sinuplasty has grabbed the ENT world by storm, and with purpose: it is a sinus treatment that does not require general anesthesia and allows you to return to work the next day. Unlike standard sinus surgery, Sinus Balloon treatment employs a series of guidewires and balloons to gently dilate the sinuses' natural drainage routes. -Minimally Invasive Sinus Surgery The purpose of surgery is to widen natural sinus drainage routes and remove obstructions to drainage and respiration. Among them are nasal polyps, blocked secretions, and hidden infections. The endoscope, a camera smaller than 1/8 inch in diameter, allows surgery through the nostrils without facial incisions.
