Office-Based Balloon Sinus Dilation: 1-Year Follow-up of a Prospective, Multicenter Study

Ann Otol Rhinol Laryngol. 2015 Aug;124(8):630-7. doi: 10.1177/0003489415573830. Epub 2015 Mar 4.


Objective: Balloon sinus dilation (BSD) instruments afford the opportunity for office-based sinus procedures in properly selected patients with chronic rhinosinusitis (CRS). This study evaluated patient-reported outcomes 1 year after office-based BSD.

Methods: Adult patients with medically refractory CRS were prospectively enrolled into a multicenter, single-arm study and treated with office-based BSD under local anesthesia. Follow-up on 203 patients was conducted at 2, 8, and 24 weeks postsurgery using validated outcome measures for quality of life (SNOT-20) and computed tomography imaging (Lund-Mackay score). After 24 weeks, patients were re-enrolled for 1-year follow-up to evaluate changes in SNOT-20 scores and revisions.

Results: All patients who re-enrolled (n = 122) completed the study, with an average follow-up of 1.4 years. Neither preoperative SNOT-20 nor Lund-Mackay CT scores were predictive of re-enrollment and return for follow-up. Compared to baseline, improvements in SNOT-20 scores remained statistically significant (P < .001) and clinically meaningful (mean decrease ≥ 0.8). In patients followed to 1.4 years, 9 of 122 (7.4%) had revision surgery.

Conclusion: Following office-based BSD, significant improvements in quality of life observed at 24 weeks were maintained 1 year postsurgery. These extended results provide further evidence of office-based BSD as an effective, minimally invasive procedure for appropriately selected patients with CRS.
