Abstract
This study was done to assess the relevance of radiological examination in comparision to endoscopic examination in diagonis of maxillary sinus lesions. X-ray para nasal sinuses was done in sixty six patients and CT scan in 18 patients. Antroscopy was performed in all the cases (133 sinuses). The correlation between X -ray examination and antroscopy was found to be poor i.e. 52.4% with 95% confidence interval of 39.5-65.5% while that between CT scanning and antroscopy was good i.e. 90% with a 95.5 confidence interval of 77.8%-100%. The difference between the two correlations with highly significant satistically (p<0.001). The findings are discussed.
