“ A Comparative Study of Chronic Sino - Nasal Diseases Between Diagnostic Nasal Endoscopy ( DNE ) And CT Scan ”

Introduction: Recently combination of diagnostic endoscopy and systematic understanding of the lateral nasal wall with CT in the coronal plane has become the corner stone in the evaluation of the PNS disease. This is the basis for the concept of FESS. Material and Method: Patients attending ENT OPD in RIMS, Ranchi with any sino-nasal complains lasting for more than 4 weeks and not responding to medical line of management. Patients are selected by random sampling method. Results: The most common co-morbidity found among the patients is chronic Rhinosinusitis in 31 cases (62%). Middle meatal purulent secretions are the most obvious finding in DNE evaluation seen in 31 (62%) cases. Anterior ethmoidal sinus haziness is seen in 37(74%) cases on CT scan with majority of cases showing associated sinus involvement. Conclusion: Sino nasal pathology has a higher preponderance in male patients and is commonly seen in the age group of 20 to 40 years. CT scan has got a better advantage compared to DNE in detecting the anatomical variants as well as to know the condition of sinus cavity and the extent of disease in sinuses.DNE can prove to be a better diagnostic modality compared to CT scan when conditions like middle meatal secretions, condition of mucosa, polyps are looked for. Thereby indicating that in all patients with Sino nasal disease both CT scan and DNE has to be done, to know the exact pathology and to plan for further management. Both CT scan and DNE are complimentary to each other.
