Abstract：
Endotracheal intubation is an airway management procedure commonly performed under general anesthesia. It is linked with postoperative voice changes. The incidence and reasons of hoarseness and vocal cord injury are not very well investigated, especially after short-term anesthesia and intubation in head and neck surgery. The aim of the study is to identify the causes of voice changes after short endotracheal anesthesia in head and neck surgery. The study will include patients scheduled for head and neck surgery under general anesthesia with endotracheal intubation up to 3 hours. There will be 3 groups of patients, as follows: thyroid surgery, non-thyroid surgery, and control group undergoing surgery outside head and neck. Videostroboscopy will be recorded before and after surgery. Further diagnostic workup will include voice status; subjective voice self-analysis; perceptive and objective acoustic voice analysis at 4 time points (preoperatively, postoperative day 2, 2 weeks and 1 month after surgery). Endotracheal intubation is a safe method of airway management although it can temporarily alter a patient\'s voice quality. It is not known how much of this is the result of anesthesia, general condition of the patient, or surgery. This trial is expected to shed some light on this issue.
摘要：
气管内插管是通常在全身麻醉下进行的气道管理程序。它与术后声音变化有关。声音嘶哑和声带损伤的发生率和原因没有很好的调查，尤其是在头颈部手术的短期麻醉和插管后。该研究的目的是确定头颈部手术中气管内麻醉后声音变化的原因。该研究将包括计划在气管插管长达3小时的全身麻醉下进行头颈部手术的患者。将有3组患者，如下：甲状腺手术，非甲状腺手术,对照组进行头颈部外手术。将在手术前后记录视频镜。进一步的诊断检查将包括语音状态；主观语音自我分析；4个时间点的感知和客观声学语音分析（术前，术后第2天，手术后2周和1个月）。气管内插管是一种安全的气道管理方法，尽管它可以暂时改变患者的语音质量。不知道有多少是麻醉的结果，患者的一般状况，或手术。预计这项审判将对这个问题有所了解。
