A comparative study of radiological and antroscopic findings in the lesions of maxillary sinus.

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.
