The clinical manifestation of vocal fold edema is mainly hoarseness, mostly due to poor vocal habits. If an electronic laryngoscopy is performed, a deformation of the free edge of the vocal folds can be seen. If the vocal cord edema is not serious, you can take rest, talk less, drink more water, and take medications such as grass coral tablets and Golden Voice. If the vocal cord edema is serious, hormones should be applied for treatment to avoid edema of the larynx, difficulty in breathing and even suffocation, and antibiotics can be injected around the vocal cord for treatment. In life, you need to pay attention to rest, forbid spicy food, and usually enhance exercise to improve your immunity.
