Sound recovery after thyroid cancer surgery can be carried out through medication and surgical treatment, and the specific treatment effect varies from person to person. For patients whose thyroid surgery has caused slight damage to the recurrent laryngeal nerve, hormonal drugs such as injectable methylprednisolone sodium succinate and prednisolone acetate tablets can be used to relieve the symptoms and improve the progression of the disease in the acute edema period. Rest is the main focus for a short period of time after surgery, and as the edema of the recurrent laryngeal nerve gradually subsides, the voice of most patients can be restored naturally. For patients whose laryngeal nerve is seriously damaged by thyroid surgery, such as those whose laryngeal nerve is partially severed or even completely severed during surgery, laryngeal nerve repair is feasible, and if combined with vocal spasm, standardized voice practice is needed to promote the compensatory effect of the other side of the vocal folds on the affected side. If you find that your voice is hoarse or unable to speak after thyroid cancer surgery, you should seek medical treatment in time and under the guidance of the doctor, and should not take medication without authorization, so as to avoid delaying the condition. Pay attention to rest on weekdays, quit smoking and drinking, and keep regular work and rest.
