  • Incidences of Device-related or Procedure-related Complications [ Time Frame: Through 12 months post-procedure ]
  • Patency of the Treated Area as Verified by CT Scan [ Time Frame: Post-treatment at 3 months ]
    Post-procedure Patency was assessed using a CT scan 3 months post-procedure. The osteomeatal complex was assessed for patency by physicians.
  • Symptomatic Score Change- Sinonasal Outcome (SNOT) 20 Score Improvement [ Time Frame: Post-treatment through 12 months ]
    Symptomatic change in SNOT 20 scores on a 5-point Likert scale where "0" = no problem to "5" = problem as bad as it can be were calculated. Baseline scores and 12 month post-procedure follow-up scores were calculated and compared. A score reduction of at least 0.8 (-0.8) from baseline to 12 months is considered statistically significant and clinically impactful.
  • Change in Sino Nasal Outcome Test (SNOT-20) scores [ Time Frame: Post-treatment at 1 week, 4 weeks, 3 months, 6 months, and 12 months ]
  • Patency of the Treated Area as Verified by CT Scan [ Time Frame: Post-treatment at 3 months ]
  • Incidences of Device-related or Procedure-related Complications [ Time Frame: Post-treatment through 12 months ]

Balloon REmodeling Antrostomy THErapy Study
Balloon REmodeling Antrostomy THErapy Study (BREATHE I)
This study is designed to evaluate safety and effectiveness of a less invasive procedure to treat maxillary only, or maxillary and anterior ethmoid, chronic sinusitis. Additionally, this study will assess the feasibility of performing the procedure under local anesthesia.
