Diagnosis of vocal cord leukoplakia: The role of a novel narrow band imaging endoscopic classification

Abstract

4. Laryngoscope, 2018.

Clinical utility and effectiveness of a training programme in the application of a new classification of narrow‐band imaging for vocal cord leukoplakia: A multicentre study

“…Subsequently, the NBI training course was taught by Dr Ni, who had rich experience with NBI laryngoscopy. The training course lasted one hour, and the content mainly included the following: (a) the basic principle of NBI technology; (b) a detailed introduction to the Ni classification of laryngeal lesions based on the morphology of the intraepithelial papillary capillary loop (IPCL); and (c) a detailed explanation of the new NBI diagnostic classification for vocal cord leukoplakia (types I‐VI) . The case images used in the training session did not appear on the test.…”

Evaluation of Vascular Patterns Using Contact Endoscopy and Narrow-Band Imaging (CE-NBI) for the Diagnosis of Vocal Fold Malignancy

“…Different classification systems for the vascular changes of vocal folds were introduced in the last years, while specific patterns have been associated with different histological diagnoses [4][5][6]24]. The proposal of the Committee on Endoscopic Laryngeal Imaging of the ELS for a descriptive guideline for vascular changes of the vocal folds introduced a simplified approach divided between longitudinal and perpendicular vascular changes.…”

Triological Best Practice: When Is Surgical Intervention Indicated for Vocal Fold Leukoplakia?

“…Narrow band imaging (NBI) endoscopy, first used in the examination of early gastrointestinal cancers, is a relatively novel imaging technique proven effective in the early diagnosis of head and neck cancers . The NBI endoscope uses a special filter to enhance the contrast between mucosa and blood vessels, allowing improved visualization of vessels.…”

“…Ni et al devised a classification system based on vascular patterns visualized on NBI endoscopy. According to this system, normal vocal fold epithelium has vessels that run parallel to the surface of the epithelium (type I).…”

“…Ni et al published a review of 120 cases of VFL classified under this system. They reported an accuracy of 90.8% in differentiating benign versus malignant lesions, significantly higher than the 70.0% accuracy when utilizing only white light imaging ( P < .0001).…”
