Remote-access hemithyroidectomy in a patient with papillary thyroid cancer after ipsilateral irradiation: a case report.

Gland Surg 2022 Mar;11(3):622-627

Department of Surgery, International Goodwill Hospital, Kanagawa, Japan.

Remote-access thyroidectomy (RAT) is becoming a more frequently used approach that can avoid scars in the neck and provide better cosmetic results than open surgery. However, there has been no surgical indication for RAT in patients who have a history of cervical treatment (surgery or irradiation), and the use of RAT has been avoided in such patients. Here, we report a case in which a remote-access endoscopic hemithyroidectomy and central lymph node dissection by the anterior chest approach was successfully performed in a patient with papillary thyroid carcinoma (a 77-year-old Japanese male) after he had undergone ipsilateral cervical radiation therapy to parotid gland cancer (mucoepidermoid carcinoma) thirteen years earlier.
