The ai/m of this study was to compare the self-reported confidence of novices in using a smartphone-enabled video otoscope, a microscope and loupes for ear examination and external ear canal procedures.
Medical students (n = 29) undertook a pre-study questionnaire to ascertain their knowledge of techniques for otoscopy and aural microsuction. Participants underwent teaching on ear anatomy, examination and procedural techniques using a microscope, loupes and smartphone-enabled video otoscopes. Confidence and preference using each modality was rated using a Likert-like questionnaire.
After teaching, all modalities demonstrated a significant increase in confidence in ear examination (p < 0.0001). Confidence in using the smartphone-enabled otoscope post-teaching was highest (p = 0.015). Overall, the smartphone-enabled video otoscope was the preferred method in all other parameters assessed including learning anatomy or pathology (51.72 per cent) and learning microsuction (65.51 per cent).
Smartphone-enabled video otoscopes provide an alternative approach to ear examination and aural microsuction that can be undertaken outside of a traditional clinical setting and can be used by novices.
本研究的目的是比较新手使用智能手机视频耳镜、显微镜和放大镜进行耳部检查和外耳道手术的自我报告的信心。
医学生（n=29）参加了一项预研究问卷调查，以确定他们对耳镜检查和耳内吸引术技术的了解。参与者接受了关于显微镜、放大镜和智能手机视频耳镜的耳部解剖、检查和程序技术的教学。使用类似于李克特量表的问卷评估每种模式的信心和偏好。
教学后，所有模式的耳部检查信心均显著提高（p<0.0001）。教学后，使用智能手机视频耳镜的信心最高（p=0.015）。总体而言，在评估的所有其他参数中，包括学习解剖学或病理学（51.72%）和学习微吸术（65.51%），智能手机视频耳镜都是首选方法。
智能手机视频耳镜为耳部检查和耳内吸引术提供了一种替代方法，可以在传统临床环境之外进行，并且可以由新手使用。
