Objectives
Narrative objectives1
We compare the clinical characteristics of patients with vocal fold leukoplakia who have visited our hospital with those who have not recurred and clarify the differences. In addition, the objective was to reduce the burden on patients to formulate a treatment policy, take countermeasures, and reduce recurrent cases.

Basic objectives -Others
Vocal fold leukoplakia is a benign disease caused by hoarseness, caused by the thickening of the squamous epithelium. The causes include various stages from temporary hyperplasia associated with inflammation such as the common cold to dysplasia involving infiltration of atypical cells into the epithelium and cancer. It is known that even if hyperplasia is found in pathological diagnosis by tissue biopsy, malignant transformation occurs only by follow-up observation. Extensive resection for complete removal of lesions impairs speech function. In addition, the canceration of recurrent lesions is still being reported. If this study reduces the rate of recurrence of vocal fold leukoplakia, it can prevent cancer associated with the recurrence and reduce the psychological, physical, and economic burden on patients associated with treatment for the recurrence.
