ABSTRACT

OBJECTIVE To investigate the value of narrow band imaging endoscopy without magnification in the diagnosis of malignant laryngeal lesions. METHODS A total of 425 patients diagnosed as laryngeal tumor from February 2013 to November 2014 were included in this study. All the cases were examined with electronic nasopharyngolaryngoscope equipped with NBI mode. The characteristics of mucosal morphology and superficial vessels of each lesion under NBI mode were evaluated for diagnosis and assessed by reference to histopathology. RESULTS The sensitivity, specificity, positive, predictive value and negative predictive value of NBI in diagnosis of malignant laryngeal lesions were 80.43%, 97.10%, 77.08% and 97.61%respectively. And NBI endoscopy is helpful to the detection of early cancer and precancerous lesions. CONCLUSION NBI endoscopy without magnification is a promising tool for improving the diagnosis of malignant laryngeal lesions.
