目的：声带注射（VFI）在办公室和手术室中越来越流行。大多数培训项目都不能教育住院医生如何进行这些注射。在本报告中，我们描述了新颖有效的教学工具，为住院医生和耳鼻喉科医生的实践教育提供了真实的VFI模拟。方法：开发了一种设备，允许使用切除的新鲜尸体喉部在真人大小的人头颈部模型中模拟经口VFI。一个单独的设置也被开发用于使用喉镜支架和尸体喉部来模拟喉镜VFI。这些VFI训练设置中的每一个都允许学生在模拟环境中执行和练习VFI，该环境具有物理和解剖限制，并且喉部解剖结构与现实生活中的VFI相似。使用新鲜的尸体喉部可以让使用者有一种真实的注射感觉。使用视觉模拟量表来测量参与者在研讨会前后对经口和显微喉镜注射技术的舒适程度。结果：从22名VFI课程参与者中收集了研讨会前和研讨会后的调查。研讨会前VFI的平均舒适水平为经口VFI 22，显微喉镜VFI 69（0 =完全不舒适，100 =非常舒适）。经口VFI术后舒适度为52，显微喉镜VFI术后舒适度为85。每种VFI技术的术前和术后舒适度评分差异显著（显微喉镜检查，p = 0.001, p = 0.001）
Objectives: Vocal fold injection (VFI) in the office setting and in the operating room is becoming increasingly popular. Most training programs fail to educate residents in performing these injections. In this report, we describe novel and effective teaching tools that provide real-life simulation of VFI for the education of residents and otolaryngologists in practice.Methods: Equipment was developed to allow the use of excised fresh cadaver larynges to simulate peroral VFI in a life-sized model of the human head and neck. A separate setup was also developed for use of a laryngoscope holder and cadaver larynges to simulate nucrolaryngoscopy VFI. Each of these VFI training setups allows the student to perform and practice VFI in a simulated setting with physical and anatomic constraints and laryngeal anatomy similar to those of real-life VFI.The use of fresh cadaver larynges allows the user to have a realistic feel of actual injection. A visual analog scale was used to measure the participants' comfort levels with the peroral and microlaryngoscopic injection techniques before and after the workshop.Results: Pre-workshop and post-workshop surveys were collected from 22 of the VFI Course participants. The mean comfort levels for VFI prior to the workshop were 22 for peroral VFI and 69 for microlaryngoscopy VFI (0 = not comfortable at all and 100 = very comfortable). The post-workshop comfort levels were 52 for peroral VFI and 85 for microlaryngoscopy VFI. The differences in the pre- and post-workshop comfort level scores for each VFI technique were significant (microlaryngoscopy, p =.001 peroral, p
