The thyroidectomy-related voice questionnaire (TVQ) is an efficient screening tool for detecting postoperative vocal dysfunction. The aim of this study was to confirm the significance of the preoperative TVQ score in thyroid surgery.
We examined 180 women who underwent total thyroidectomy with central lymph node dissection from March 2014 to May 2016. Based on the preoperative TVQ score, participants were categorized under "normal" (TVQ score <5) and "abnormal" (TVQ score ≥5) groups. The laryngoscopic examination and acoustic analysis were performed and the TVQ score assessed before and after surgery (2 weeks, 2 months, and 8 months).
In the normal group, the TVQ score increased up to 2 months postoperatively and had decreased at 8 months postoperatively but was significantly higher than the preoperative TVQ score. In the abnormal group, the TVQ score increased up to 2 months postoperatively but had recovered similar to the preoperative TVQ score 8 months postoperatively. The preoperative TVQ score in the abnormal group moderately correlated with the final TVQ score; however, the preoperative TVQ score in the normal group did not correlate with the TVQ score 8 months postoperatively.
During preoperative patient counseling, it is important to explain that voice changes without vocal cord palsy may occur postoperatively and that it may take a long time to resolve, particularly in patients with a normal preoperative TVQ score.
甲状腺切除术相关的嗓音问卷（TVQ）是一种有效的筛查工具，用于检测术后嗓音功能障碍。本研究旨在确认术前 TVQ 评分在甲状腺手术中的意义。
我们检查了 180 名 2014 年 3 月至 2016 年 5 月期间接受甲状腺全切除术和中央淋巴结清扫术的女性患者。根据术前 TVQ 评分，患者分为“正常”（TVQ 评分<5）和“异常”（TVQ 评分≥5）组。手术前后（术后 2 周、2 个月和 8 个月）进行喉镜检查和声学分析，并评估 TVQ 评分。
在正常组中，TVQ 评分在术后 2 个月内增加，8 个月后下降，但仍明显高于术前 TVQ 评分。在异常组中，TVQ 评分在术后 2 个月内增加，但在 8 个月后恢复到术前 TVQ 评分水平。异常组的术前 TVQ 评分与最终 TVQ 评分中度相关，而正常组的术前 TVQ 评分与术后 8 个月的 TVQ 评分无相关性。
在术前患者咨询中，重要的是要解释到，即使没有声带麻痹，术后也可能出现嗓音变化，且可能需要很长时间才能恢复，尤其是术前 TVQ 评分正常的患者。
