Sinuplasty (Dilating the Ostia of the Sinuses) is getting more popular as it is less invasive .Instead of using endoscopic instruments such as microdebriders and forceps, surgeons use balloons to dilate the sinus openings. This technique is similar to angioplasty, the use of balloons to open blocked blood vessels. The balloon is inflated and enlarges the sinus opening.
Here I try to dilate the ostium of the maxillary sinus by using a Foleys catheter, very inexpensive method.
