The objective of this study is to show that long-term symptom improvement after sinus balloon dilation is not worse than symptom improvement after functional endoscopic sinus surgery (FESS) and that fewer postoperative debridements are required after balloon dilation than after FESS.

Primary Outcome Measures:
  • Sinus Symptom Improvement [ Time Frame: Baseline and 1-year ]
    Change from baseline in overall 20-item Sino-Nasal Outcome Test (SNOT-20) score. The SNOT-20 is a validated patient reported survey of 20 items related to sinonasal symptoms and severity assessed over the previous 2 weeks. Each item is scored from 0 (no problem) to 5 (problem as bad as it can be). The individual item scores are averaged to provide and overall score that ranges from 0 (best) to 5 (worst).

  • Debridements [ Time Frame: 1-year ]
    Number of postoperative debridements per participant

Secondary Outcome Measures:
  • Revision Rate [ Time Frame: 1-year ]
    Number of participants requiring repeat sinus procedures

  • Complication Rate [ Time Frame: Duration of study (minimum of 12 months) ]
    Number of participants experiencing 1 or more serious adverse events related to the device and/or procedure

  • Recovery Time [ Time Frame: 6-months ]
    Mean time (days) after procedure for participants to return to normal activities

Enrollment: 151
Study Start Date: December 2011
Study Completion Date: May 2014
Primary Completion Date: February 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Balloon Sinus Dilation
XprESS Multi-Sinus Dilation Balloon, FinESS Sinus Treatment
Device: Balloon Sinus Dilation
Balloon sinus dilation using the XprESS Multi-Sinus Dilation Tool or the FinESS SInus Treatment
Active Comparator: Functional Endoscopic Sinus Surgery
Traditional endoscopic sinus surgery (maxillary antrostomy and uncinectomy with optional anterior ethmoidectomy) using cutting, grasping, and microdebrider tools.
Procedure: Functional Endoscopic Sinus Surgery
Endoscopic sinus surgery, specifically, maxillary antrostomy and uncinectomy with optional anterior ethmoidectomy

Detailed Description:
This is a postmarket, multicenter, prospective, randomized clinical trial conducted at up to 15 US clinical sites comparing the efficacy of balloon sinus dilation with traditional endoscopic sinus surgery. The primary hypotheses were to demonstrate that: 1) long-term change in sinus symptoms after balloon dilation is not worse (non-inferior) than after FESS, and 2) balloon dilation is superior to FESS for a reduction in the number of postoperative debridements per patient. A minimum of 36 participants per arm is required to test the primary hypotheses. All participants will be followed through a minimum of 12 months post treatment.
