Clinical Evaluation to Confirm Safety and Efficacy of Sinuplasty in the Paranasal Sinuses (CLEAR)

• Number of Sinuses With Patency of Sinus Ostium After Sinuplasty [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
  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 ] [ Designated as safety issue: Yes ]
  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).

• Patency of sinus ostium after sinuplasty.
• Adverse event rate following sinuplasty procedure.

A multi-center, non-randomized, prospective post-market evaluation of sinuplasty in paranasal sinuses.

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.

Inclusion Criteria:

1. Age 18 years and greater
2. Both male and female patients eligible
3. Diagnosis of chronic sinusitis that is not responsive to medical management
4. Planned endoscopic sinus surgery (recommended by PI, consented to by patient)

Exclusion Criteria:

1. Extensive sinonasal polyps
2. Extensive previous sinonasal surgery
3. Extensive sinonasal osteoneogenesis
4. Cystic fibrosis
5. Sampter's Triad (Aspirin sensitivity, Asthma, Sinonasal polyposis)
6. Sinonasal tumors or obstructive lesions
7. History of facial trauma that distorts sinus anatomy and precludes access to the sinus ostium
