Abstract:
Objective To evaluate different methods to explose recurrent laryngeal nerve (RLN)based on the location of thyroid diseses and anatomic path of the RLN,to avoid the RLN damage in thyroid surgery.Methods A total of 755 cases underwent total lobectomy was studied retrospectively.RLN was explosed in each case.Results A total of 963 RLN was exposed in 755 cases,among those 658 RLN were exposed by lateral approach,106 by inferior approach,and 199 by superior approach.It was showed that 694 RLN traveled deep to the inferior throid artery and 119 superficial to the artery,98 through between two branches of the artery,and 62 with the cross of the nerve branches and the artery branches.Before entering larynx,578 RLN gave off branches and 385 had no branches.Non-recurrent laryngeal nerves were found in 2 cases.There were 6 cases who presented with hoarseness after thyroidectomy and undergoing reexploration,among them RLN were legated in 4 cases and severed in 2 cases.Conclusions The anatomic relation of RLN is relatively complicated.Lateral,inferior or superior aproach may be used for exposure of RLN to decrease risks of injury to the nerve.
