[Clinical significance of recurrent laryngeal nerve of normal anatomy in thyroid surgery].

OBJECTIVE: To discuss the method of recurrent laryngeal nerve anatomy of thyroid surgery, for avoiding recurrent laryngeal nerve injury. METHOD: Recurrent laryngeal nerve of all 247 cases were found along tracheoesophageal groove or angle of thyroid cartilage, in front of the recurrent laryngeal nerve showed up next to the thyroid cartilage angle and cricothyroid membrane, or down to thyroid anatomy revealed under the lower pole artery and vein, and not have to deliberately look for a branch of the recurrent laryngeal nerve, a total of 258 recurrent laryngeal nerve were found. RESULT: Among two hundred and forty-seven cases, the recurrent laryngeal nerve injury was two cases, injury rate was 0.8%. And the two cases were incomplete injury, which about a month were back to normal, and significant deviation was found with no pre-conventional anatomy of of recurrent laryngeal nerve of 276 cases (P < 0.05). CONCLUSION: Conventional recurrent laryngeal nerve anatomy in thyroid surgery could effectively avoiding recurrent laryngeal nerve injury.
