Patients 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.
Results
Sixty-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 symptoms, with 15% same and 0% worsened. Revision treatment was required in seven of 195 sinuses (3.6%) in six of 65 patients (9.2%).
Conclusion
Patients who receive balloon catheter sinusotomy in endoscopic sinus surgery have significant improvement in symptoms two years after surgery. Radiographic evidence also confirms resolution of disease after two years. This demonstrates durability of clinical results previously reported at 24 weeks and one year after surgery.
