甲状腺癌手術時に遭遇したNon-recurrent Laryngeal Nerveの3例

抄録

Three cases of right non-recurrent laryngeal nerve recognized during operations for thyroid cancer are reported. This anomaly of the recurrent nerve is explained by the process of nerve and blood vessel development from the embryologic branchial arches, since it is known to be associated with an anomalous origin of the right subclavian artery from the aortic arch. In two of our three cases, an aberrant right subclavian artery was postoperatively detected by esophagography and MRI. Recurrent nerve injury is one ofthe most important complications of posed by thyroid operations, and surgeons must be awere of the most important complications of posed by thyroid operations, and surgeons must be awere of the possibility of non-recurrent laryngeal nerves, especially on the right side.
