According to the results reported on ClinicalTrials.gov, this trial enrolled 151 people with sinus problems — 76 assigned to a procedure called Balloon Sinus Dilation (BSD) and 75 assigned to a more traditional surgical approach called Functional Endoscopic Sinus Surgery (FESS). The trial was measuring two main things: how much participants' sinus symptoms changed over time (using a 20-question symptom survey called the SNOT-20, where a lower score means fewer or less severe symptoms), and how many follow-up clinic visits involving nasal cleaning (called "debridements") each person needed after their procedure. By the end of the study, 71 people in the BSD group and 59 in the FESS group had completed all follow-up. The reported data shows that both groups had similar reductions in their symptom survey scores. On average, BSD participants' SNOT-20 scores dropped by 1.59 points from their starting score, while FESS participants' scores dropped by 1.60 points — essentially the same change in both groups. When it came to post-procedure clinic cleaning visits, the reported data shows BSD participants averaged 0.23 visits per person, compared to 1.03 visits per person in the FESS group. For the secondary measures, the reported data shows that 1 participant in each group needed a repeat sinus procedure. The number of participants who experienced a serious adverse event (an unexpected harmful event considered related to the device or procedure) was reported as zero in both groups. The reported data also shows that BSD participants returned to normal activities in an average of 1.7 days, compared to 5.0 days for FESS participants.
