Abstract    Objective    To study the anatomy near ligament of Berry in the View of Endoscopic Thyroidectomy, discuss the programmed endoscopic thyroid surgery. Methods    From 346 side’s endoscopic Thyroid lobectomies were analyzed retrospectively, important structural which restriction Thyroid lobectomy and its relationship with recurrent laryngeal nerve were analyzed. Results    From the view of endoscopic thyroid lobectomy, ITA and PGA two artery layers were identified，these anatomic landmarks appears rates were 75.2%,52.6% in the left and 82.8%,74.2% in the right, Respectively. Conclusion    ITA layer and PGA layer often leads to U-shaped stretch to the Recurrent laryngeal nerve, these anatomical landmarks are helpful to the protection of the recurrent laryngeal nerve and the artery of superior parathyroid gland.
