Vocal fold nodules are a kind of chronic laryngitis, which refers to symmetrical nodule-like growths at the junction of the front middle 1/3 of the vocal folds on both sides of the edge of the vocal folds, preventing the vocal folds from closing and causing low and coarse sound, and even hoarseness and loss of voice. Vocal fold nodules are mostly caused by long-term inappropriate use of sound or excessive use of sound, as the vocal fold tension gradually increases with the rise in frequency, and the vocal fold muscles are overly tense and squeeze each other, causing impact. Generally, the damage at the junction of the anterior and middle 1/3 of the vocal folds is severe, so the mucosa is limited edema, hyperplasia, keratinization, interstitial fibrosis and the formation of symmetric pinpoint or corn-sized nodules. Laryngoscopically, small pale white bumps, translucent and smooth, with small blood vessels visible at the base, are seen on both sides of the anterior middle 1/3 of the vocal fold margin, preventing closure of the vocal fold during vocalization. Vocal fold nodules are often found in people who use their voices professionally or who like to shout and vocalize improperly. Nowadays, many children love to shout and speak very loudly, often with all their strength and high voice, and cry very loudly, which can easily damage the vocal folds locally, thus forming nodules and showing hoarseness. Therefore, parents should always remind their children to speak quietly and not to shout indiscriminately to prevent the appearance of vocal cord nodules.
