The vagus nerve and its branches can be damaged by diseases, such as diabetes, or by surgery to the stomach or small intestine.

What is the effect of injury of external laryngeal nerve?

The external laryngeal nerve is the sole motor nerve supply of the cricothyroid muscle, which is the tensor of vocal folds and raises the pitch of voice [9]. Post-thyroidectomy ESLN injury symptoms include voice fatigue, breathy voice, and a decrease in voice range [10].

What are complications of thyroidectomy?

Major postoperative complications include wound infection, bleeding, airway obstruction (compressing hematoma, tracheomalacia), hypocalcemia, thyroid storm (uncommon, usually associated with Grave’s disease) and recurrent laryngeal nerve injury. Incidence is 3-5%.
