title: Sino-nasal assessment questionnaire: a specific outcome measure for rhinosinusitis, but what is the range in the asymptomatic population?
abstract: The sino-nasal assessment questionnaire is a system used for scoring the symptoms of chronic rhinosinusitis. However, the range of scores for this questionnaire in the healthy adult population is unknown. We aimed to establish this by recruiting 100 healthy volunteers and comparing their sino-nasal assessment questionnaire scores with those of 100 individuals who had undergone sinus surgery for rhinosinusitis. The difference in mean scores in the symptomatic group (44.62) and the asymptomatic group (8.46) was statistically significant. However, there was substantial overlap between the scores of the two groups. Factors such as age, gender and smoking did not have a statistically significant impact on the eventual score in the asymptomatic group. We believe that symptom scores can only be used effectively when the range in the asymptomatic population is known. This is so that disease severity can be gauged in the context of the normal population and post-operative improvements can be forecast.
