BACKGROUND: This is a comparative analysis of the diagnostic accuracy of narrow band imaging (NBI) and laryngovideostroboscopy (LVS) in the assessment of premalignant and malignant vocal fold lesions. METHODS: A prospective analysis was performed on 105 consecutive patients with vocal fold lesions. The NBI and LVS were obtained before the microsurgery. RESULTS: The NBI and LVS showed no significant differences in identifying premalignant and malignant pathologies. However, in analysis restricted to identification of only malignant lesions, the specificity (88.9% vs 20.6%), accuracy (90.5% vs 51.4%), and positive predictive value (PPV; 84.8% vs 45.1%) were significantly higher for NBI (P value < .001; .015; and .045, respectively). A comparison of LVS scored results relative to each NBI type revealed statistically significant differences (P < .001). A moderate positive correlation between NBI and LVS was demonstrated (P = .54). CONCLUSION: The NBI and LVS are useful, complementary tools in evaluating early potential vocal fold malignancies. The NBI was superior to LVS on several statistical analyses.
