Abstract
Duplication of the recurrent nerve is a rare anatomical variation. It constitutes a real anatomical trap during thyroidectomy. The recurrent nerve is located based on the inferior thyroid artery, Gruber's ligament and the inferior horn of the thyroid cartilage. However, Doppler ultrasound and monitoring remain effective methods for not only determining the position of the recurrent nerve but also eliminating any anatomical variations that pose a functional risk, sometimes life-threatening, during thyroidectomy. We report two cases of left recurrent nerve splitting during total thyroidectomies.
