The aim of this prospective study was to identify the arterial anomalies constantly associated with nonrecurrent inferior laryngeal nerve by preoperative ultrasonography and impact on recurrent inferior laryngeal nerve palsy (RILN).
The study included 332 patients who underwent thyroidectomy or parathyroidectomy between 2009 February and 2011 October. Preoperative ultrasonography was performed to all patients to identify vascular anomalies related to NRILN. CT was performed only in patients with NRILN predicted with preoperative ultrasonography. Systematic nerve dissection was performed surgically. Patient characteristics, type of NRILN, preoperative and postoperative vocal cord mobility and morbidity were recorded.
The NRILN was identified in 6 patients on the right side (1.94%). Preoperative ultrasonography predicted NRILN in all cases (accuracy 100%).
Ultrasonography is a very reliable and simple method to be used in preoperative assessment to identify vascular anomaly associated with NRILN to make optimal surgical decisions against nerve damage in patients undergoing thyroidectomy or parathyroidectomy. Adequate surgical technique is of great importance.
本前瞻性研究旨在通过术前超声检查确定与非复发性喉返神经相关的动脉异常，并探讨其对复发性喉返神经麻痹（RILN）的影响。
本研究纳入了 2009 年 2 月至 2011 年 10 月期间接受甲状腺或甲状旁腺切除术的 332 例患者。对所有患者进行术前超声检查以识别与 NRILN 相关的血管异常。仅对术前超声预测有 NRILN 的患者进行 CT 检查。术中进行系统神经解剖。记录患者特征、NRILN 类型、术前和术后声带活动度以及发病率。
在 6 例右侧患者（1.94%）中发现了 NRILN。术前超声检查在所有病例中均预测到 NRILN（准确性 100%）。
超声检查是一种非常可靠和简单的术前评估方法，可用于识别与 NRILN 相关的血管异常，以便在接受甲状腺或甲状旁腺切除术的患者中做出最佳手术决策以防止神经损伤。适当的手术技术非常重要。
