Discussion on Recurrent Laryngeal Nerve Injury in Thyroid Surgery

Objective To study the factors that cause recurrent laryngeal nerve injury in thyroid surgery and the prevention. Methods 200 cases of patients underwent thyroid surgery in our hospital were studied. Of the 200 cases, 49 cases had been revealed the recurrent laryngeal nerve, 151 cases had not. The incidence of recurrent laryngeal nerve injury of all the patients was counted. Results Recurrent laryngeal nerve injury occurred in 4 cases of the 200 cases, the occurrence probability was 2%. The incidence of recurrent laryngeal nerve injury by the surgical method that did not expose laryngeal nerve was 0.66%, but 6.12% by the surgical method that exposed laryngeal nerve, the difference was statistically significant(P0.05). Conclusion Due to the recurrent laryngeal nerve anatomical complexity, so during the thyroid surgery, the recurrent laryngeal nerve anatomy should be paid attention and the operation should be done carefully, which help to reduce the incidence of recurrent laryngeal nerve injury.
