Abstract：
OBJECTIVE: To propose a scoring system based on laryngoscopic characteristics for the differential diagnosis of benign and malignant vocal fold leukoplakia.
METHODS: Laryngoscopic images from 200 vocal fold leukoplakia cases were retrospectively analysed. The laryngoscopic signs of benign and malignant vocal fold leukoplakia were compared, and statistically significant features were assigned and accumulated to establish the leukoplakia finding score.
RESULTS: A total of five indicators associated with malignant vocal fold leukoplakia were included to construct the leukoplakia finding score, with a possible range of 0-10 points. A score of 6 points or more was indicative of a diagnosis of malignant vocal fold leukoplakia. The sensitivity, specificity and accuracy values of the leukoplakia finding score were 93.8 per cent, 83.6 per cent and 86.0 per cent, respectively. The consistency in the leukoplakia finding score obtained by different laryngologists was strong (kappa = 0.809).
CONCLUSIONS: This scoring system based on laryngoscopic characteristics has high diagnostic value for distinguishing benign and malignant vocal fold leukoplakia.

摘要：
目的：提出一种基于喉镜特征的评分系统，用于鉴别良恶性声带白斑。
方法：回顾性分析200例声带白斑患者的喉镜图像。比较良性和恶性声带白斑的喉镜征象，并对具有统计学意义的特征进行分配和累积,以建立白斑发现评分.
结果：共纳入与恶性声带白斑相关的五项指标，以构建白斑发现评分，可能的范围为0-10点。6分或以上的分数表明诊断为恶性声带白斑。敏感性,白斑发现评分的特异性和准确性值分别为93.8％，分别为83.6%和86.0%,分别。不同喉科医师获得的白斑发现评分的一致性很强（kappa=0.809）。
结论：这种基于喉镜特征的评分系统对区分良恶性声带白斑具有较高的诊断价值。
