Hoarseness may be caused by excessive use of voice, vocal polyps, vocal cord paralysis, etc. Different treatments should be chosen according to different diseases. 1. Excessive use of voice: A muffled throat indicates that the vocal cords are severely congested or edematous, so avoid talking too much. If you work as a salesman or a teacher and have to use your voice more, it is recommended that you can use a sound amplifying device to reduce the unconscious raising of your voice. 2. Vocal polyps: Saline with budesonide suspension can be used for nebulization treatment, together with oral treatment with Chinese medicines such as Golden Voice Pills and Huang’s Voice Pills. If the effect of standardized conservative treatment is not good, surgery can be considered. 3. Vocal cord paralysis: relevant examinations should be perfected to identify the causes, common causes include skull base tumor, thyroid disease, lung cancer and laryngeal tumor, etc. Surgery, radiotherapy and other comprehensive treatment are often adopted. When patients find the symptoms of hoarseness, do not take medication on your own, it is recommended to actively consult a doctor for examination, and standardize the use of medication and treatment after a clear diagnosis.
