To study factors related to recurrent laryngeal nerve (RLN) paralysis, a major complication of thyroidectomy.
Retrospective study of outcome of patient's medical records in Xijing Hospital and Tumor Hospital of Liaoning Province. Records of 1,563 patients who underwent thyroidectomy by departments of general surgery, ENT and head & neck surgery at these two hospitals were reviewed for RLN paralysis.
RLN injury was analyzed in relation to types of surgery, RLN identification, and histopathology.
The incidence of RLN paralysis was 7.8%, and significantly related to the histopathologic findings of malignancy (P < 0.01). The positive identification and prevention of RLN would not be in either permanent RLN paralysis or temporary RLN paralysis, and the types of surgery were not found to be significant factors in both paralysis.
RLNs should be identified to avoid iatrogenic injury and subsequent paralysis, and meticulous surgical technique should be applied in patients whose results of biopsy suggested malignancy.
研究甲状腺切除术后主要并发症喉返神经（RLN）麻痹的相关因素。
对西京医院和辽宁省肿瘤医院患者病历结果进行回顾性研究。回顾了这两家医院普通外科、耳鼻喉科和头颈外科进行甲状腺切除术的1563例患者的病历，以了解喉返神经麻痹情况。
分析喉返神经损伤与手术类型、喉返神经识别及组织病理学的关系。
喉返神经麻痹发生率为7.8%，与恶性肿瘤的组织病理学结果显著相关（P<0.01）。喉返神经的正确识别和预防对永久性或暂时性喉返神经麻痹均无影响，且手术类型在两种麻痹中均未被发现是重要因素。
应识别喉返神经以避免医源性损伤及随后的麻痹，对于活检结果提示恶性肿瘤的患者应采用细致的手术技术。
