Long-term outcome analysis of balloon catheter sinusotomy: Two-year follow-up

ObjectiveAssess two-year postoperative clinical outcomes for patients receiving balloon catheter sinusotomy.MethodsPatients who had sinus ostia dilated with balloon catheters were prospectively evaluated two years after surgery by Sinonasal Outcome Test (SNOT-20) and computed tomographic (CT) scan.ResultsSixty-five patients (195 ballooned sinuses) were followed for two years after surgery, including 34 “balloon-only” patients and 31 “hybrid” patients. SNOT-20 symptom scores were significantly improved from baseline (0.87 vs 2.17 baseline, P < 0.001) and stable compared to six months and one year; this was the case for both balloon-only (1.09 vs 2.09, P < 0.001) and hybrid (0.64 vs 2.26, P < 0.001) patients. Lund-MacKay CT scores were significantly improved from baseline (2.69 vs 9.66, P < 0.001) and stable compared to one year, confirmed for both balloon-only (1.75 vs 5.67, P < 0.015) and hybrid (3.25 vs 12.05, P < 0.001) subsets of patients. A total of 85% of patients reported improvement of their sinus ...
