Vocal cord leukoplakia is not laryngeal cancer, but leukoplakia is a precancerous lesion. Therefore, the appearance of vocal cord leukoplakia should be taken seriously. Long-term smoking, chronic laryngitis, improper use of voice, acid reflux, decreased immunity and other factors may make the squamous epithelium of the vocal fold mucosa overproliferate and keratinize, so that grayish-white keratinized patches appear on the surface of the vocal fold mucosa, which may lead to the occurrence of white spots on the vocal folds. Symptoms of hoarseness, discomfort and foreign body sensation in the larynx occur. Leukoplakia can develop into laryngeal cancer, but not all vocal cord leukoplakia will develop into laryngeal cancer. After the occurrence of vocal cord leukoplakia, it is recommended to quit smoking and drinking, actively treat chronic inflammation of the larynx, and those with acid reflux should be treated with antacid therapy, and apply omeprazole and other medicines according to the doctor’s prescription. If the lesion is mild, it is recommended to closely follow up and observe; if the lesion is not cured for a long time, biopsy should be taken to exclude cancer. If conservative treatment is ineffective, microsurgery under supportive laryngoscope can be used to remove the lesion.
