OBJECTIVES: Objectives were 1) to determine whether a correlation exists between @entity158 or @entity10 and @entity50 severity by computed tomography (CT) scan in @entity1 with rhinosinusitis and 2) to compare disease severity and @entity158 perception in two geographically diverse North American @entity1 populations. STUDY DESIGN: Prospective @entity1 questionnaire before CT scan of the paranasal sinuses. METHODS: @entity1 with refractory rhinosinusitis were recruited at the University of Texas Medical Branch (Galveston, TX) and the University of Alberta (Edmonton, Alberta, Canada). Before CT scanning, @entity1 completed a @entity158 questionnaire. All scans were interpreted by one neuroradiologist and were scored using the Lund-McKay, Harvard, and Kennedy staging systems for rhinosinusitis. RESULTS: Fifty-one @entity1 completed questionnaires (27 were Canadian). There was no correlation between @entity158 severity and disease severity reflected by any of the three staging systems used (P >.05). The mean @entity158 score for the U.S. @entity1 was 7.3, and for Canadian @entity1 , 5.2. The mean CT scores for U.S. versus Canadian @entity1 were as follows: Lund-McKay, 2.6 versus 6.6; Harvard, 0.7 versus 1.0; and Kennedy, 1.4 versus 2.2. The Canadian @entity1 had more severe disease on CT scan (Lund-McKay, P <or=.001; Harvard, P <or=.005; and Kennedy, P <or=.007) while reporting less severe @entity158 (P <or=.004). CONCLUSIONS: There was no correlation between @entity158 severity and disease severity by sinus CT scan as graded by the Lund-McKay, Harvard, or Kennedy staging system. @entity158 and @entity10 , although frequent complaints of @entity1 with rhinosinusitis, are not useful predictors of @entity50 severity. There appears to be a difference in @entity158 perception between the two North American populations.
