Primary Outcome Measures:
  • Technical Success: Sinuses Successfully Treated With Balloon Dilation [ Time Frame: Index procedure ]
    Number of successful dilations out of all attempted dilations. Success is defined as the device successfully delivered to the target sinus, inflated, deflated, and withdrawn from the treated sinus.

  • Complications [ Time Frame: Index procedure through 3-month follow-up ]
    Number of subjects who experience complications. Complications are defined as serious device or procedure related adverse events.

Secondary Outcome Measures:
  • Change in Quality of Life From Baseline Through Completion [ Time Frame: Baseline to 6-month follow-up ]
    Change in sinonasal symptom severity between the baseline preprocedure assessment and follow-up assessment. Sinus symptom severity is measured using the Sinus and Nasal Quality of Life Survey (SN-5) that is a validated tool for use in pediatric patients (completed by caregivers). The 5 survey items are scored from 1 (best) to 7 (worst) and averaged to provide an overall score.

  • Number of Subjects Who Undergo a Revision or Additional Surgery During the Study [ Time Frame: Procedure-6 month follow up ]
    Any surgical intervention that is performed in the sinus(es) following the index procedure will be reported
