Medical Therapy Versus Balloon Sinus Dilation for Patients With Chronic Rhinosinusitis

Comparison of Change Measured by CSS Medication and Sinusitis Symptom Subscores and Total Score From Baseline

The Chronic Sinusitis Survey (CSS) is a 6 question, duration-based survey ("during the past 8 weeks") used to evaluate surgical outcomes for CRS patients. The CSS asks 3 questions each about symptoms and medication usage, yielding a symptom subscore, a medication subscore, and a total score. The symptom-based section contains pain or pressure, nasal congestion or difficulty to breathe through the nose, and rhinorrhea or postnasal drip. The medication-based section contains: antibiotics, prescription nasal sprays, and sinus medications in pill form. The duration of symptoms is scored 0 ("7-8 Weeks") to 4 ("0 Weeks"), and a total score is normalized from 0 (worst) to 100 (best). The Secondary Endpoint is the comparison of change as measured by average CSS medication and sinusitis symptom sub-scores at 12, 24, and 52 weeks , and average total CSS score at 12 and 52 weeks for subjects electing BSD versus medical management. Higher score indicates greater improvement.

Time frame: 12, 24, and 52 weeks post treatment

Change in RSDI

The Rhinosinusitis Disability Index (RSDI) is a 30-question survey which includes 3 individual subscales to measure physical, functional, and emotional scores as well as a total score. There is no specified recall period. Scale values are scored 0 ("Never") to 4 ("Always") and total score ranges from 0 (best) to 120 (worst). Subscores are summed to calculate a total score. Higher score indicates increased impact of sinus disease. The Secondary Endpoint is comparison of change in patient-reported QOL as measured by RSDI total, physical, functional, and emotional sub-scores at 12, 24, and 52 weeks compared to baseline for subjects electing BSD versus medical management. Lower score indicates greater improvement (decreased impact of sinus disease).
