Abstract：
Thyroidectomy is one of the most common neck surgery done worldwide. It is associated with debilitating post-operative voice changes even without recurrent laryngeal nerve (RLN) injury. Aims and Objectives: To study the impact of thyroidectomy on voice parameters in the absence of Recurrent Laryngeal Nerve and External Branch of Superior Laryngeal Nerve injury and comparison between the pre and post-operative changes in the subjective and objective voice parameters. Methodology: Patients fulfilling the inclusion criteria underwent thyroidectomy. The Subjective voice assessment was done using Voice Impairment Score (VIS) and objective parameters were analyzed using Multi-Dimensional Voice Program (MDVP) pre-operatively and post-operatively at 1 week, 1 month and 3 months interval. Results: On MDVP analysis of patients, a fall in Mean F0 (Hz), Minimum F0 (Hz) and Maximum F0 (Hz) values was noted at 1 week after surgery. But a trend toward the pre-operative values was observed at 3 months post-operatively.
摘要：
甲状腺切除术是世界范围内最常见的颈部手术之一。即使在没有喉返神经（RLN）损伤的情况下，它也与衰弱的术后声音变化有关。目的：研究甲状腺切除术对喉返神经和喉上神经外支损伤情况下嗓音参数的影响，并比较手术前后主客观嗓音参数的变化。方法：符合纳入标准的患者接受甲状腺切除术。使用语音障碍评分（VIS）进行主观语音评估，并在手术前和术后1周时使用多维语音程序（MDVP）分析客观参数。1个月和3个月的间隔。结果：对患者的MDVP分析，平均F0(Hz)下降，在手术后1周记录最小F0(Hz)和最大F0(Hz)值。但是在术后3个月观察到了术前值的趋势。
