  • NONRECURRENT INFERIOR LARYNGEAL NERVE AND THEIR CLINICAL SIGNIFICANCE (A REPORT OF 2 CASES)

    目的 了解喉不返神经临床解剖特点,总结甲状腺手术中预防其损伤的经验。方法 分析2例喉不返神经临床资料,结合文献讨论甲状腺手术中预防其损伤的有关问题。结果 本组2例经手术证实,喉不返神经均位于右侧; 右喉返神经缺如,术中未损伤。结论 甲状腺手术中发现横行于颈动脉鞘和喉之间任何索状结构或探查喉返神经缺如,须显露迷走神经(颈段)以避免损伤喉不返神经。

  • Effect of Preoperative Carotid Duplex Ultrasound to Prevent Nonrecurrent Laryngeal Nerve Injury During Thyroid Surgery

    ObjectiveTo investigate the clinical value of cervical vascular color Doppler ultrasound for dignosis of nonrecurrent laryngeal nerve before thyroid surgery. MethodsThere were 1931 cases of thyroid patients treated between January 2010 to Jule 2014, group these patients according to the results of preoperative chest radiograph examination, the chest radiograph shows abnormal vessels image were group A (45 cases), no abnormalities were group B (1886 cases). Before operaton, made patients of group A to have routine carotid duplex ultrasound to identify whether the right subclavian artery abnormalities. All patients were exposed to conventional methods of recurrent laryngeal nerve during surgery. ResultsThe 45 patients of group A, chest angiography showed 17 cases with right subclavian artery abnormalities, they were confirmed that all the 17 patients were nonrecurrent laryngeal nerve by surgery, no damage cases. The other 28 cases showed a normal right subclavian artery and no cases of nonrecurrent laryngeal nerve. The 1886 patients in group B, surgical exploration found four cases with nonrecurrent laryngeal nerve, injury in 1 case. The 21 patients whose nonrecurrent laryngeal nerve were on the right side, there were no left side with nonrecurrent laryngeal nerve and no co-exist cases of nonrecurrent and recurrent laryngeal nerve. The average exposure time of nonrecurrent laryngeal nerve in patients of group A (17 cases) was significantly shorter than that group B[(4.28±1.08) min vs. (15.50±2.08) min, t=-15.978, P=0.000]. ConclusionsThe cervical vascular color Doppler ultrasound examination before thyroid surgery can be adjuvant used, if there is the right subclavian artery abnormalities, it showes that there is the right side nonrecurrent laryngeal nerve. So as to effectively prevent the damage of nonrecurrent laryngeal nerve during thyroid surgery.

  • Identification and protection of non-recurrent laryngeal nerve in thyroidectomy

    Objective To explore anatomical features and variation of non-recurrent laryngeal nerve and to summarize identification method, operation skill, and damage treatment experience of it. Method The clinical data of 15 patients with non-recurrent laryngeal nerve in 4 054 patients who underwent thyroidectomy from our division by the same medical group from January 2006 to January 2016 were retrospectively analyzed. Results A total of 6 626 recurrent laryngeal nerve (left side 3 248, right side 3 378) were exposed in 4 054 cases. Fifteen patients with non-recurrent laryngeal nerve were detected with an incidence of 0.23% (15/6 626), all located on the right side. There were 3 males and 12 females. There were 3 cases of type Ⅰ, 10 cases of type Ⅱa, 2 cases of type Ⅱb. And 2 patients with non-recurrent laryngeal nerve were injured. Conclusions Incidence of non-recurrent laryngeal nerve is lower, most of which occur on right side of neck, there is a high injury rate for its special anatomical location. It’s key to prevent nerve injury for careful interpreting preoperative auxiliary examination results and improving awareness of non-recurrent laryngeal nerve, fining dissection, conventional exposuring recurrent laryngeal nerve, and accurate using nerve monitor during operation.
