Identification techniques of the recurrent laryngeal nerve in endoscopic thyroidectomy

Abstract

To investigate the application of identification techniques of the recurrent laryngeal nerve (RLN) in endothyroidectomies. Routine identification of the RLN was performed in a series of 20 consecutive endothyroidectomies, and the clinical data were reviewed. Totally 20 RLNs were dissected. Neither transient nor permanent RLN injury occurred. To expose RLN, both sharp and blunt dissection should be applied skillfully. Thorough liberation of the thyroid lobe is essential for the identification of RLN. It is safe and feasible to remove the thyroid and identify the RLN simultaneously.
