Abstract:
Objective To investigate the anatomic feature and exposing methods of recurrent laryngeal nerve(RLN) in thyroid surgery. Methods The data of 327 cases of thyroid tumor were analyzed retrospectively. The anatomic feature, injury and prevention of RLN were discussed. Of all the cases, 293 RLNs (242 cases) were anatomically exposed. Results The temporary injury rates of RLN was 1.65% (4/242) in the exposed group and 8.23% (7/85) in the unexposed group with a persistent injury rate of 2.35%(2/85). The differences of temporary injury rates and persistent injury rates between the two groups were statistically significant (P<0.05). 67.23% (197/293) of the RLNs had two branches before entering larynx, 61.09%(179/293) of RLNs were posterior to the inferior thyroid artery and 31.39% (92/293) anterior to the inferior thyroid artery, 4.09% (12/293) passed through the bifurcation of inferior thyroid artery, and 4. 13% (10/293) were not related to the inferior thyroid artery. The incidence of non-recurrent laryngeal nerve (inferior laryngeal nerve) was 0.68% (2/293). Conclusions The anatomic relation of RLN is relatively complicated along its journey. The injury of RLN could be reduced with designed exposal during the thyroid surgery.
