説明

A 48-year-old female was diagnosed as having papillary carcinoma in the right lobe of the thyroid.Right lobectomy, isthmectomy, and neck lymphnode dissection (D2a)were performed. Because the thyroid cancer had invaded the right recurrent nerve, this nerve was cut, and neither end of the amputated nerve could be anastomosed directly. In this case, the right ansa cervicalis had already been excised in the neck lymphnode dissection,so we used the left ansa cervicalis for the nerve transfer.Left ansa cervicalis-right recurrent nerve anastomosis was performed in front of the thyroid cartilage.Nerve fiber and epineurium were each sutured with 9-0 nylon.To avoid the tension from the nerve stitches,the epineurium was stitched to the surrounding tissue. The patient who had performed left ansa cervicalis-right recurrent nerve anastomosis had better phonating function than patients with an excised recurrent nerve. It is concluded that ansa cervicalis-contralateral recurrent nerve anastomosis is one of an effective reconstruction technique for the recurrent nerve.
