Balloon Sinus Dilation
Select patients may be candidates for new minimally invasive technology-balloon catheter sinus dilation. This can be accomplished either under general anesthesia in a traditional operating room, or under local anesthesia in the office setting.

Balloon catheter dilation for the treatment of chronic sinusitis involves placement and inflation of a balloon catheter within an obstructed frontal, sphenoid, or maxillary sinus ostium/opening. The balloon catheter is placed using transnasal endoscopy. A transantral approach underneath the upper lip may also be used for direct access to the maxillary sinus.

Inflation of the balloon is intended to enlarge the natural sinus ostium/opening by compressing mucosa and displacing local bony structures. This technique has been used as an alternative or adjunct to conventional endoscopic sinus surgery which involves surgical excision of some mucosa and bone.
