Vocal cord polyps are mainly caused by overuse of the voice by patients, or by edema of the mucous membrane due to smoking, alcohol, and physical or chemical irritations, which gradually form vocal cord polyps. During an examination with an electronic laryngoscope, if whitening of the vocal cord mucosa or symptoms such as folds or erosion are found, it may indicate an early stage lesion of a tumor, or that a tumor has developed, which is often seen in cases of leukoplakia or squamous carcinoma of the vocal cords. If such conditions are discovered, it is important for the patient to take them seriously and promptly visit a hospital for a pathological biopsy to determine if there has been a pathological change in the vocal cords. If a pathological change is confirmed, it is necessary to promptly remove the pathological tissue through carbon dioxide laser surgery or support laryngoscopy surgery to achieve timely treatment.
