The teaching of endoscopic endonasal surgery has always been difficult because of the complex structure of the nasal cavity, and the unique endoscopic view angle and endoscopic surgical tools. In this study, we have designed a 3D printed multi-color model for training of endoscopic endonasal surgery, and obtained preliminary application results.
The 3D printed model contained facial skin, bony skeleton, internal carotid artery, turbinate, optic chiasm, and a special sellar base with appropriate colors. After it was printed, six otolaryngologists and neurosurgeons assessed the model. Twenty graduate students and residents from otolaryngology or neurosurgery, without prior experience in endoscopic endonasal surgery were recruited and consented for the training. The training results were recorded. The subjective feeling of participants in terms of using 3D printed model in surgical training was investigated after training.
All experts strongly agreed or agreed that the 3D printed model has realistic anatomical structure of nasal passage and appropriate colors for different parts, and is a good teaching tool. As the trainees practiced more, the rate and quality of endoscopic operation increased gradually. Compared to the first practice, all recorded training parameters were improved significantly (all < 0.05). All participants strongly agreed or agreed that they benefited from the training and the 3D printed model can inspire interest and enthusiasm of endoscopic endonasal surgical training.
This 3D printed model has realistic anatomical structure of nasal passage and appropriate colors for different parts, and could be a good teaching tool of endoscopic endonasal surgery.
由于鼻腔结构复杂，且鼻内镜视角和手术工具独特，鼻内镜鼻内手术的教学一直颇具难度。在本研究中，我们设计了一种用于鼻内镜鼻内手术训练的3D打印多色模型，并取得了初步应用成果。
3D打印模型包含面部皮肤、骨骼、颈内动脉、鼻甲、视交叉以及带有适当颜色的特殊鞍底。打印完成后，六名耳鼻喉科医生和神经外科医生对模型进行了评估。招募了20名来自耳鼻喉科或神经外科且此前无鼻内镜鼻内手术经验的研究生和住院医师，并征得他们同意参与训练。记录训练结果。训练结束后，调查参与者在手术训练中使用3D打印模型的主观感受。
所有专家均强烈同意或同意该3D打印模型具有逼真的鼻道解剖结构，不同部位颜色合适，是一种良好的教学工具。随着受训者练习增多，内镜操作的速度和质量逐渐提高。与首次练习相比，所有记录的训练参数均有显著改善（均P<0.05）。所有参与者均强烈同意或同意他们从训练中受益，且3D打印模型能够激发鼻内镜鼻内手术训练的兴趣和热情。
这种3D打印模型具有逼真的鼻道解剖结构，不同部位颜色合适，可能是鼻内镜鼻内手术的一种良好教学工具。
