Correlation of radiologic evidence of rhinosinusitis with the criteria set by task force for rhinosinusitis [TFR]

ABSTRACT

The development of consensus guidelines for diagnosis and treatment for rhinosinusitis has been significant challenge for otolaryngology and primary care providers. A major break through emerged in 1997 when task force for Rhinosinusitis [TFR] set forth consensus diagnostic guidelines for acute, sub-acute and chronic sinusitis, later revised in 2003. But still there is no gold standard identified to diagnose chronic rhinosinusitis. In our study we have seen the degree of agreement between TFR criteria for CRS and CT scan paranasal sinuses findings. To examine the degree of agreement between the task force criteria for chronic rhinosinusitis and CT scan findings for rhinosinusitis. All the patients had two major or one major with two minor symptoms defined by TFR criteria were enrolled. All the patients underwent assessment as per TFR criteria and diagnosed positive or negative. CT scan paranasal sinuses of all the patients were also done and were assessed as per Lund Mackay CT scoring system. Degree of agreement between these two diagnostic modalities was seen. Forty patients were enrolled for this study. Degree of agreement between TFR criteria for CRS Lund Mackay CT scati scoring system was found to be 0.615 [+1-95% Cl + 0.54 1- +/- 0.689].When we saw the sensitivity and specificity of TRF criteria against CT scan it was calculated to be 88% and 100% respectively. Positive and negative predictive value for this criteria was came out to be 100% and 25%. Degree of agreement between TFR criteria and CT scan for CRS is satisfactory. TFR criteria is highly specific to diagnose CRS
