Hoarseness after thyroid nodule removal may be due to damage to nerves, such as the recurrent laryngeal nerve, etc. Oral medications that nourish the nerves can be prescribed. In severe cases, surgery is needed. After thyroid nodule surgery, hoarseness in the short term may be caused by pulling the nerve or hematoma compression of the nerve during the operation, which can be observed for a short period of time, and generally can be restored to normal on its own. If the voice does not recover after a long period of time, it should be clarified whether it is caused by nerve dissection, and nerve anastomosis can be performed after full evaluation by the surgeon. If you experience discomfort after thyroid nodule surgery, it is recommended that you consult a doctor in a timely manner and choose the appropriate treatment plan to avoid adverse consequences.
