Abstract: 【Abstract】 Objective To summarize the experience of routine exposure of recurrent laryngeal nerve (RLN) by different anatomical landmarks. Methods 400 patients with thyroid surgery were includ?lage (group C), and tracheoesophageal groove (group D). Time of RNL exposure, RNL injury (temporary or permanent) were recorded in each group and analyzed. Results Among the groups, the shortest anatomi?cal time of RNL was in group C, the longest in group B, and the amount of bleeding had no significant dif?ferences in 4 groups. Ultrasonic scalpel helped to reduce operative hemorrhage and shorten operation time. Conclusions The way of recurrent laryngeal nerve exposure in thyroid surgery should be based on the surgeon′s preference and performed individualized anatomical way.
