Introduction: NBI is relatively new optical image enhancement technology. The wavelength is centered on 415 (blue) & 540 nm (green). Blue and green light has different depth of penetration thus highlights mucosa and submucosa. Material and Methods: It is a retrospective study on 45 patients of early premalignant and malignant glottic cancers. Patient undergone preoperative, peroperative and postoperative white light and NBI endoscopy. NBI findings (using Ni etal classification) compared with the histopathological diagnosis. Results: The preoperative distribution of cases on the basis of T-staging using WL/NBI was mild-moderate dysplasia-15, Tis- 4, T1a-16, T1b-8, T2a-2. The peroperative distribution using the same tool changed the distribution with mild-moderate dysplasia-12,Tis-6, T1a-13, T1b-10, T2a-3, T2b-1. Conclusion: The upstaging of disease was noted in all stages of the T-disease using NBI. With the aid of angled telescope peroperatively mapping and staging of the disease is done. Thus it helps in better surgical dissection and results.
