Abstract

Background. The purpose of this study was to assess the value of narrow band imaging (NBI) endoscopy in the diagnosis of phar-yngolaryngeal lesions and to demonstrate the validity of a new NBI-based classification of their vascular pattern. Methods. From 2009 to 2011, 248 patients with pharyngolaryngeal lesions underwent NBI-endoscopic evaluation. NBI findings were classified into 5 types according to the Ni classification and were compared with histopathological reports. Sensitivity, specificity, accuracy, and positive predictive value (PPV) and negative predictive value (NPV) were calculated. Results. Sensitivity, specificity, accuracy, PPV, and NPV were 97.4%, 84.6%, 92.7%, 91.6%, and 95.1%, respectively. Ninety-eight percent of histologically malignant lesions corresponded to type V endoscopic pattern, whereas 84.8% of the non-neoplastic lesions corresponded to a type I to IV pattern. Conclusion. The NBI ability to detect changes in the mucosal microvas-culature can be useful for distinguishing nonmalignant from malignant lesions. An internationally accepted NBI-endoscopic classification may contribute to the further definition of the diagnostic validity of this technique.
