Objective

To assess the diagnostic accuracy of CT PNS in diagnosing fungal sinusitis and its relation with endoscopy and

histopathology

 Methodology

This cross sectional retrospective study was conducted at Benazir Bhutto Hospital, Rawalpindi from July 2022

to July 2023. Data of 153 individuals was collected who underwent CT PNS, Endoscopy and histopathology. Data was

analyzed in SPSS version. 26.

 Results

The mean age of individuals was 39.38 ± 7.05 years. Out of 153 individuals, 87 (56.9%) were males and 66

(43.1%) were females. On CT PNS, out of 153 individuals, 122 (79.7%) individuals were positive for fungal sinusitis but 31

(20.3%) were found negative. On histopathology, results were almost same as results obtained on CT, on histopathology

i.e. 119 (77.8%) positive and 34 (22.2%) negative. Against endoscopy as well as against histopathology, CT PNS showed

sensitivity and specificity of 95% and 73.5%, respectively. The overall diagnostic accuracy of CT PNS was 90.2% against

endoscopy.

 Conclusion

Thus CT PNS serves as a good diagnostic tool for detection of fungal sinusitis and a reliable guide for the

surgeon, since diseases confined to the nose and paranasal sinuses may be effectively done under endoscopic techniques.
