2.1.1
Removal of part or all of the thyroid gland (partial or total thyroidectomy) may be indicated in the treatment of thyroid enlargement (goitre), thyrotoxicosis or malignancy. The thyroid gland is located close to the right and left recurrent laryngeal nerves (RLNs) which innervate the vocal cords. Damage to an RLN during thyroid surgery may result in temporary or permanent hoarseness, or, in the case of bilateral damage, breathing difficulties and inability to speak.
