Davaris N, et al. - Authors studied in this retrospective study to analyze the inter- and intra-observer variability and diagnostic value of narrow band imaging (NBI) and white light endoscopy (WLE) and to investigate the probable impact of previous laryngeal surgery on the detection rates of laryngeal malignancy. They observed NBI more sensitive as compared to WLE in diagnosing laryngeal malignancy with more accuracy and diagnostic odds ratio and determined flexible transnasal endoscopy, a relevant tool in the diagnosis of laryngeal malignancy.
