Introduction: Endoscopes have markedly improved visualization for sinus surgery, but expanding concepts of FESS have outplaced available operative instrumentation. The surgical techniques are continually improved, but the basic concepts of the newer instruments have changed very little.
Methods:The main objective of this study is to study the diagnostic nasal endoscopy and sinonasal grading. A total of 60 cases who are diagnosed to have sinonasal polyposis were included in this study. By using 30 degree Hopkin's rod endoscope of 1 st , 2 nd and 3 rd pass were done. Middle meatus was examined in all patients and the polyps were graded according to the standard classification.
