Abstract:
Objecfive:To investigate the clinical characteristics and surgical management of tumor invasion on recurrent laryngeal nerve at the entrance of larynx in thyroid cancer.Methods:The clinical data of 30 patients with recurrent laryngeal nerve invasion by thyroid cancer from Aug 2012 to Aug 2018 in Cangzhou Central Hospital were analyzed retrospectively. Patients were divided into groups A (14 cases ,nerve was invaded at the larynx) and group B (16 cases,nerve was involved in other parts).Results:Between the two groups, operation time, intraoperative blood loss, number of tumor focus, adhesion and infiltration were not statistically different ( P>0.05). The tumor size in group A was smaller ( t=-3.614, P=0.001), the lymph node metastasis rate was lower ( χ2=5.593, P=0.018), and the microcancer rate was higher ( χ2=4.051, P=0.044).Follow up data up to 24 months showed there were no significant difference in postoperative hoarseness , laryngoscope abnormality and recurrence rate between the two groups (all P>0.05). Conclusion:Patients of thyroid cancer with recurrent laryngeal nerve invasion at the larynx had relatively small tumor size, higher proportion of microcancer, lower rate of lymph node metastasiss.
