Abstract
OBJECTIVES: This study was an attempt to determine whether sinus mucosal inflammation is related to computed tomographic findings and patients' reported symptoms in chronic rhinosinusitis (CRS) without polyposis. METHODS: I retrospectively reviewed the clinical symptom scores according to the Rhinosinusitis Symptom Inventory (RSI), the radiographic findings, and the histopathologic findings in the paranasal sinus mucosa for a consecutive series of adult patients who underwent endoscopic sinus surgery for CRS. Linear regression analysis was conducted for the relationship between tissue pathology inflammatory severity score graded on a 5-point Likert scale and the RSI symptom domains. A similar analysis was conducted for the relationship between the pathology inflammatory score and the total Lund score. RESULTS: The study cohort consisted of 115 adult patients (mean age, 40.2 years). The mean Lund score for the cohort was 8.8 (95% confidence interval, 7.9 to 9.7), and the mean pathology severity score was 2.1 (median, 2.0). The mean total symptom score for the overall cohort was 41.3; the mean total symptom scores for pathology severity grades 0, 1, 2, 3, and 4 were 25.0, 43.8, 41.8, 42.4, and 32.8, respectively. No significant association could be identified between pathology severity and any of the 5 RSI symptom domains (nasal, facial, oropharyngeal, systemic, and total symptoms; all p > .436, linear regression). A statistically significant relationship between total Lund score and pathology severity was identified (p < .001). CONCLUSIONS: Poor correlation exists between the histopathologic severity of sinonasal inflammation and self-reported symptom scores in CRS. Histopathologic inflammatory grade alone fails to stratify CRS cases according to disease symptom severity. Histopathologic inflammation and computed tomographic findings correlate strongly.
