Subtotal thyroidectomy is currently performed with either local or general anesthesia, depending on the patient’s condition, physical status, and other factors. In general, the patient is conscious during local anesthesia, and the procedure is more painful because of the pulling sensation and the need to maintain a posterior cervical position. The physical and mental state of the patient is high. Therefore, in clinical practice, general anesthesia is mostly used if the patient can tolerate it.
