Vocal cord nodules are symmetrical nodular protuberances on the free edges of both vocal cords. Clinically, vocal cord nodules are mainly related to improper use of the voice and are prone to recurrence. Recurrence factors primarily involve inappropriate voice use, voice abuse, and other irritants such as tobacco, alcohol, chili peppers, and other spicy foods, as well as frequent recurring upper respiratory infections. Therefore, clinically, in addition to medication, such as drugs that clear the throat and benefit the voice, attention should also be paid to diet structure and normal voice use to avoid excessive voice abuse.
