Objectives: To investigate the pathological contribution of vocal fold leukoplakia (VFL) of type II in narrow-band imaging (NBI) classification and morphological characteristics to improve pathological prediction. Material and Methods: The 59 VFL patients with type II in 2019 Ni classification in NBI were included. The pathological reports were collected and divided following 2005 WHO Blue Book. Low-risk VFL contained non-, mild, moderate dysplasia, high-risk VFL included severe dysplasia. The morphological classification and laryngoscopic scoring system were employed to evaluate leukoplakia for pathological prediction. Results: The pathologies contained 1 case of leukoplakia with non-dysplasia, 12 of mild dysplasia, 15 of moderate dysplasia, 8 of severe dysplasia, and 23 of carcinoma. The 30 smooth VFL contained 1 non-dysplasia, 12 mild dysplasia, 14 moderate dysplasia, 2 severe dysplasia, and 1 carcinoma. The 29 rough cases included 1 moderate dysplasia, 6 severe dysplasia, and 22 carcinomas. Laryngoscopic scoring system revealed irregular texture, large size, and thick lesion as factors in relationship with high-risk leukoplakia in univariate ( P = .002, <.001, <.001) and multivariate ( P = .025, .002, .016) analysis, irregular texture was the most accurate predictor of high-risk VFL pathology. Conclusions and Significance: The pathologies of VFL with type II in NBI classification were hard to be predicted. Morphological irregular/rough texture contributed to predict high-risk pathology in leukoplakia.
