This study aimed to identify the effect of lateral neck dissection on voice change in thyroidectomised patients.
Medical records from 264 patients who underwent thyroidectomy with (n = 65) or without (n = 199) lateral neck dissection were reviewed. Clinical and voice evaluation data were compared between the two groups.
Patients who underwent surgery that included lateral neck dissection had lower fundamental frequencies and speaking fundamental frequencies. They also had a higher incidence of asymmetric mucosal wave and vocal fold oedema on videostroboscopy during the first month after surgery, with the incidence of vocal fold oedema remaining significantly higher at three months. Self-assessed voice quality scores were significantly higher in lateral neck dissection patients at both one and three months after surgery.
In thyroidectomised patients, lateral neck dissection lowers the vocal pitch in the initial period after surgery and induces vocal fold oedema that persists for several months. Although most objective parameters improved within a month, subjective symptoms lasted for longer.
本研究旨在确定侧颈清扫术对甲状腺切除患者声音变化的影响。
回顾了264例行甲状腺切除术的患者的病历，其中65例进行了侧颈清扫术，199例未进行侧颈清扫术。比较两组的临床和声音评估数据。
接受包括侧颈清扫术在内的手术的患者基频和说话基频较低。术后第一个月，他们在频闪喉镜检查中黏膜波不对称和声带水肿的发生率也较高，声带水肿的发生率在术后三个月仍显著较高。侧颈清扫术患者在术后1个月和3个月的自我评估声音质量评分均显著更高。
在甲状腺切除患者中，侧颈清扫术在术后初期会降低音调，并导致持续数月的声带水肿。尽管大多数客观参数在一个月内有所改善，但主观症状持续时间更长。
