2、loped.The deep cervical fascia is divided in the midline and the strap muscles are retracted laterally,exposing the anterior surface of the thyroid lobe.Occasionally,in cases of large goiters,better exposure can be obtained by dividing the strap muscles transversely.45 The thyroid lobe is retracted
3、medially and is bluntly dissected from the surrounding fascia.The middle thyroid vein is encountered and is ligated close to the thyroid.46 The superior thyroid vessels are then individually ligated and divided at the level of the superior pole,rather than cephalad to it,in order to protect the exte
4、rnal branch of the superior laryngeal nerve from damage.This nerve can be seen in many patients.47 The thyroid lobe is retracted medially again and,by careful blunt dissection,the recurrent laryngeal nerve,the inferior thyroid artery,and the parathyroid glands are identified.The inferior thyroid art
5、ery is not ligated laterally as a single trunk.Rather,each small branch is ligated and divided at a point distal to the parathyroid glands(see arrows in insert)in order to preserve their blood supply.The thyroid lobe can then be removed from its tracheal attachments if a lobectomy is to be performed
