The common causes of hoarseness are acute and chronic laryngitis, vocal polyps, or laryngeal tumors, etc. The causes are different and the treatments are not the same. 1. Acute and chronic laryngitis: such as excessive use of the voice, long-term smoking and drinking, eating spicy stimulants, pathogenic infections, etc., will cause patients with acute and chronic laryngeal inflammation, resulting in patients with hoarse voice symptoms. It is recommended that patients use their voices scientifically, drink a moderate amount of water, eat a light diet, and cooperate with glucocorticoid nebulization and other symptomatic treatment. 2. Vocal polyps: Vocal polyps can lead to incomplete closure of the vocal folds during articulation, thus causing hoarseness or speechlessness. If the effect of conservative drug treatment is not good, surgery is recommended. 3. Tumor lesions: such as laryngeal cancer, thyroid cancer, etc., can lead to hoarseness or speechlessness, and it is recommended that patients go to the hospital for surgical treatment or radiotherapy in time after early detection. Patients with hoarseness and speechlessness need to go to the hospital for examination in time to find out the cause of the disease, and then go for treatment under the doctor’s guidance to avoid deterioration of the condition.
