Abstract: 【Abstract】〓Objective〓To explore the protective method for the recurrent laryngeal nerve in recurrent nodular goiter patients surgery. Methods〓A retrospective analysis was conducted on 32 patients who underent the second surgery of recurrent nodular goiter. Results〓By experienced operation, there was a clear sign of Berry ligament and Zukerkandl tubercle in all 32 patients, and the recurrent laryngeal nerve was exposed well enough with this way. Three out of 32 patients were complicated by temporary hoarseness after the surgery and recovered after neurotrophic treatment and physical therapy for less than 4 weeks. Conclusion〓The second surgery of recurrent nodular goiter patients is challenged by the adhesions of thyroid and its peripheral tissues. Locating the Berry ligament and Zukerkandl tubercle by experienced operative skills is an essential method to protect the recurrent laryngeal nerve from surgical iatrogenic injury.
