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.
