Hoarseness after drinking is mainly considered to be due to alcohol stimulation, causing pharyngeal vascular congestion, resulting in vocal cord edema. As alcohol can stimulate the pharyngeal mucosa, so that capillary dilation, vascular permeability increases, there may also be inflammatory exudation resulting in redness and swelling of the vocal folds. In addition, after drinking alcohol, the patient may have excessive use of voice so that the edema involves the vocal folds, resulting in nodules and polyps, causing hoarseness, and in severe cases, even loss of voice. At this time, the patient should avoid the stimulation of alcohol and tobacco on the one hand, and avoid making noise on the other hand. If the situation is more serious, the patient can be treated with budesonide nebulizer inhalation, and if the patient’s voice continues to be hoarse, the patient can be diagnosed through fiberoptic laryngoscopy, and the presence of polyps in the vocal folds and Renk’s edema will require surgery.
