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 enabling 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.

Further study details as provided by Acclarent:

Primary Outcome Measures:
  • Comparison of the total cost of ESS (with balloon) in office vs. ESS (with or without balloon) in the OR, including operative costs, and post-operative costs [ Time Frame: June 2010 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Safety and effectiveness of ESS (with balloon) in office vs. ESS (with or without balloon) in the OR, by assessments of patency, Kennedy-Lund endoscopic scores, revisions, sinus infections, Lund-MacKay CT scores, days off work and quality of life [ Time Frame: June 2010 ] [ Designated as safety issue: Yes ]
