Value of Different Types of Narrow Band Imaging in the Diagnosis of Benign and Malignant Vocal Cord Leukoplakia
Objective To investigate the value of types of white light mode and narrow band imaging(NBI)mode under electronic laryngoscope in differential diagnosis of properties of vocal cord leukoplakia(V CL).Methods 136 VCL patients were examined by white light mode and NBI mode.The pathological characteristics of patients with different properties of lesions were compared,and the value of different types in the diagnosis of VCL properties was analyzed.Results The proportions of smoking,involvement of anterior commissure and involvement range ≥ 50％in the benign group were lower than those in the malignant group(P＜0.05).The NI type of NBI mode had the highest accuracy in diagnosing the properties of VCL lesions,followed by the CHEN type of white light mode.The NI type of NBI mode had the highest Kappa value in identifying VCL properties.Conclusions Both white light mode and NBI mode under electronic laryngoscope have certain value in the identification of VCL properties,and the consistency between NI type ofNBI mode and pathological examination is the highest.
