Abstract

The purpose of the study was to study and compare the importance of 70 degree endoscopy, direct laryngoscopy and CT scan in showing the extent of laryngeal tumours which would then decide the course of treatment for the patient. A total of 25 patients were included in the study and all patients underwent 70 degree endoscopy, direct laryngoscopy and CT scan examination. The CT scan findings were taken as gold standard and the T staging of the laryngeal tumours was compared with 70 degree endoscopy and direct laryngoscopy which was done using Cohens Kappa statistics. The sensitivity of 70 degree endoscopy in staging T1 laryngeal tumors was 100%, T2 tumors was 57.1%, T3 tumors was 62.5 % and T4 tumors was 0. The overall staging accuracy of 70 degree endoscopy was 0.44. The sensitivity of direct laryngoscopy in staging T1 laryngeal tumors was 100%, T2 tumors was 100%, T3 tumors was 62.5 % and T4 tumors was 0. The overall staging accuracy of direct laryngoscopy was 0.56.
