Abstract: Objective To investigate the effect of combined dyclonine and lidocaine anesthesia in the examination of the larynx using narrow-band endoscopy. Methods Two hundred forty patients with laryngeal disease were examined using narrow-band imaging endoscopy. The subjects were randomly divided into three groups-dyclonine group, lidocaine group, and dyclonine with lidocaine group(80 subjects in each group), and the total effective rate was observed. The VAS scores were also recorded. Results The total effective rates were 70%(dyclonine group), 90%(lidocaine group), and 88.75%(dyclonine with lidocaine group), and the difference between the combined anesthesia group and lidocaine group was not statistically significant. The VAS score was lowest in the combined group(4.38±2.48), followed by the lidocaine group(4.78±2.83), and the dyclonine group(5.94±2.70). The difference was statistically significant. Conclusion The application of combined dyclonine and lidocaine is a safe and effective anesthetic technique for performing narrow-band imaging endoscopy in patients with laryngeal disease. Dyclonine alone does not induce adequate anesthesia for complete narrow-band endoscopy.
