Aim : To examine the accuracy of CT-scan in diagnosing nasal septal perforation Study Design: Prospective / Observational Place & Duration of Study : Departments of Diagnostic Radiology and ENT, Head & Neck Surgery, Civil Hospital Quetta from 1st January 2019 to 30th June 2019. Methods: One hundred and five patients of both genders clinically diagnosed to have nasal septal perforation were included.

Biopsy of the lesion was performed. Results: There were 67 patients were males while 38 patients were females with mean age 33.6 +/- 9.15 years. Eighty eight (83.81 %) patients were diagnosed to have nasal septal perforation by CT scan and 86 (81.90 %) patients had nasal septal perforation by histopathology. In patients with nasal septal perforation, we observed sensitivity, specificity, PPV and NPV with respect to CT was 92.32%, 82.35%, 96.51% and 73.68% respectively. Accuracy rate of CT-scan was 97.73%. Conclusion: CT scan plays an important role in diagnosing nasal septal perforation after histopathological examination. The accuracy rate of CT scan was 97.73%.
