The thyroid lobe is bluntly dissected free from its investing fascia and rotated medially. The middle thyroid vein is ligated (Fig. 15C). The superior pole of the thyroid is dissected free, and care is taken to identify and preserve the external branch of the superior laryngeal nerve (see Fig. 6). The superior pole vessels are ligated adjacent to the thyroid lobe, rather than cephalic to it, to prevent damage to this nerve (Fig. 15D). This nerve can be visualized over 90% of patients if it is carefully dissected. 51 The inferior thyroid artery and recurrent laryngeal nerve are identified (Fig. 15E). To preserve blood supply to the parathyroid glands, the inferior thyroid artery should not be ligated laterally; rather, its branches should be ligated individually on the capsule of the lobe after they have supplied the parathyroid glands (Fig. 15F). The parathyroid glands are identified, and an
