5 CONCLUSION
The differential diagnosis of benign and malignant vocal cord leukoplakia is challenging for laryngologists. The morphology of vocal cord leukoplakia under conventional laryngoscopy has a certain correspondence with its pathological properties, but the subjective factors are strong, and there is no clear objective standard. The establishment of this scoring method was based on the comprehensive consideration of the factors associated with malignant vocal cord leukoplakia. This scoring system was simplified for easy memorization during office laryngoscopy, so that the vocal cord leukoplakia can be preliminarily evaluated by this scoring for the pathological properties without biopsy, avoiding unnecessary invasive injury and helping to protect the function of vocal cords. However, whether this scoring system can be well applied clinically needs to be further verified by a multicenter clinical study.
