Narrow band imaging (NBI) is reported to improve the diagnostic accuracy of head and neck cancers. The purpose of this review was to evaluate the diagnostic accuracy of NBI in the literature. A systematic review was performed in PubMed, Web of Knowledge, and the Cochrane Library until March 2015. Two reviewers independently assessed articles and extracted data. Meta-analyses were performed in MetaDisc 1.6. Five hundred seventeen studies were identified and 17 were included in this study. Combined use of NBI and white light imaging (WLI) showed high diagnostic accuracies for primary, recurrent, and nasopharyngeal lesions. Methodological heterogeneity exists and meta-analyses were only appropriate for cancers of unknown primary (CUP) in which NBI performed on 115 patients across 4 studies demonstrated high sensitivity (74.1
