According to the results reported on ClinicalTrials.gov, this trial involved 44 children (all in a single group who received the balloon sinus procedure). Of those, 33 completed the study and 11 did not finish. The trial was measuring two main things: whether any problems directly caused by the balloon device occurred over 12 months, and whether children's sinus symptom scores changed after the procedure. There was no comparison group — everyone in the study received the same treatment. The reported data shows that zero device-related problems were recorded over the 12-month follow-up period. For sinus symptoms, the trial used a questionnaire called the SN-5, which is scored between 1 and 7 — a lower score is meant to indicate fewer symptoms. The reported average reduction in score from before the procedure to 52 weeks afterwards was 2.00 points. On the secondary measures, the reported data shows that the balloon successfully reached and opened the targeted sinus openings in approximately 90.9% of cases. Around 68.3% of participants were reported to have used less sinus medication at their last recorded check-in. Zero additional procedures (such as irrigation or cleaning) were reported as needed after the initial treatment. The reported average number of days children missed school during the 12-month follow-up was 5.75 days. It is worth noting that this trial had no comparison group, so the numbers above describe what was recorded for this one group only. These are the results as reported to ClinicalTrials.gov.
