Primary Outcome Measures:
  • Number of Sinuses With Patency of Sinus Ostium After Sinuplasty [ Time Frame: 24 weeks ]
    Patency of sinus ostium after sinuplasty will be determined by nasal endoscopic examination. The investigator will make a clinical judgment as to whether or not this has been achieved.

  • Number of Participants With Adverse Events Following Sinuplasty Procedure [ Time Frame: 24 weeks ]
    Adverse event rate at 24 weeks: comprised of all observed peri-operative adverse events which were recorded on dedicated CRFs and any observed or patient-reported post-operative adverse events will be similarly recorded (through 24 week follow-up).

Secondary Outcome Measures:
  • Number of Participants Experiencing Relief of Sinus Symptoms [ Time Frame: Week 24 ]
    To gain general insight into the ability of balloon catheter sinus ostial dilation to relieve sinus symptoms, scores from the pre-operative SNOT-20 evaluations were compared to scores from the post-procedure SNOT-20 evaluations at 24 weeks following the procedure. The number of participants who showed aggregate symptom relief are recorded here as having been successfully treated.

Detailed Description:

Sinusitis is a common healthcare problem that significantly reduces quality of life for people around the world. Patients suffer from headache, facial discomfort, nasal congestion, nasal drainage, loss of the sense of smell and malaise. Sinusitis is responsible for major healthcare expenditure and loss of workplace productivity.

The rationale of this study is to collect data on the effectiveness and safety of balloon dilation of the Frontal, Maxillary and Sphenoid sinuses by treating patients and observing them for a six month period of time following the procedure. Six month follow-up data is important to demonstrate the effectiveness of balloon catheter dilation.
