文摘目的:探讨术中神经监测(intraoperative neuromonitoring,IONM)对分化型甲状腺癌(differentiated thyroid carcinoma,DTC)患者主观语音结局的影响。方法:回顾性分析从2018年9月—2019年3月在中山大学第一附属医院接受甲状腺手术的DTC患者,分为IONM组和非IONM组,采用倾向评分匹配法(propensity score matching,PSM),比较两组患者的临床基线特征和术后主观语音结果。结果:在预防性中央区淋巴结清扫亚组中,两组患者术后1个月、6个月的声音障碍指数⁃10(voice handi⁃cap index⁃10,VHI⁃10)总分及甲状腺癌特异性生活质量(thyroid cancer specific quality of life,THYCA⁃QoL)问卷的声音领域均无统计学差异(P>0.05)。在靠近或侵犯后包膜亚组中,IONM组术后1个月、6个月的THYCA⁃QoL问卷中的声音领域评分中位数(四分位数)均为0.00(0.00,0.00),低于非IONM组的0.00(0.00,33.33),差异有统计学意义(P=0.034)。均值均为5.73,明显低于非IONM组的15.66(P=0.029)。VHI⁃10问卷两组差异无统计学意义。结论:IONM对DTC患者及预防性中央区淋巴结清扫术亚组患者的主观发声障碍没有显著影响,但可明显改善靠近后包膜高危组患者术后主观声音异常。
