A teaching model was sought to improve canine otoscopy skill and reduce use of teaching dogs.
An otoscopy teaching model was printed in a flexible medium on a desktop three-dimensional printer from a magnetic resonance image of a canine external ear canal. The model was mounted in a polyvinyl dog mannequin. Validation of the teaching model was sought from student, faculty, and dog perspective. Student perception of prelaboratory training was assessed using a survey regarding their experience. Otoscopy skill was assessed by faculty grading the ear anatomy visualized as well as the time required to prepare for and perform otoscopy and the time to the dog's first sign of aversion. The time data were used to assess whether there was a reduction in use of teaching dogs. Data from students exposed to the otoscopy model as part of their prelaboratory training (n = 20) were compared with those that were not exposed to the model (n = 19).
The students found prelaboratory training with the model significantly more helpful than prelaboratory training without the model in all aspects of otoscopy (P < 0.05). Use of the model did not alter otoscopy skill (structures seen or time taken) or decrease dog use.
The students found the model helpful, but the best that can be said is the model did not negatively impact their otoscopy skill acquisition. Although the outcome of the study did not indicate a reduction in teaching dog use, the model has replaced live dog otoscopy in the institute's teaching program for initial canine otoscopy exposure.
旨在寻求一种教学模型，以提高犬耳镜检查技能并减少教学犬的使用。
利用犬外耳道的磁共振图像，在桌面三维打印机上以柔性介质打印出耳镜检查教学模型。该模型安装在聚乙烯狗模型中。从学生、教师和犬的角度对教学模型进行验证。通过一项关于学生经验的调查来评估他们对实验室前培训的看法。耳镜检查技能由教师根据可视化的耳部解剖结构、准备和进行耳镜检查所需的时间以及犬首次出现厌恶迹象的时间进行评分。时间数据用于评估教学犬的使用是否减少。将作为实验室前培训一部分接触耳镜检查模型的学生（n = 20）的数据与未接触该模型的学生（n = 19）的数据进行比较。
学生们发现，在耳镜检查的各个方面，使用模型进行实验室前培训比不使用模型的培训明显更有帮助（P < 0.05）。模型的使用并未改变耳镜检查技能（观察到的结构或所用时间），也未减少教学犬的使用。
学生们认为该模型有帮助，但充其量可以说该模型对他们耳镜检查技能的获得没有负面影响。尽管研究结果并未表明教学犬的使用有所减少，但该模型已在该研究所的教学计划中取代了活体犬耳镜检查，用于犬耳镜检查的初次接触。
