Balloon Sinus Dilation In Office or OR

In this study, endoscopic sinus surgery will be performed either in the physician's office or
in the operating room (OR). Patients treated in the physician's office will have endoscopic
sinus surgery performed with the balloon sinuplasty devices. Patients treated in the OR will
have endoscopic sinus surgery performed with or without balloon sinuplasty devices. Both
primary treatment of sinusitis as well as revision of previously treated sinuses will be
allowed. Resource absorption will be evaluated for both venues.
