The American Academy of Otolaryngology-Head and Neck Surgery Foundation's (AAO-HNSF's) 3D-Printed Temporal Bone Working Group was formed with the goal of sharing information and experience relating to the development of 3D-printed temporal bone models. The group conducted a multi-institutional study to directly compare several recently developed models.

The working group convened in 2018. The various methods in which 3D virtual models had been created and printed in physical form were then shared and recorded. This allowed for comparison of the advantages, disadvantages, and costs of each method. In addition, a drilling event was held during the October 2018 AAO-HNSF Annual Meeting. Each model was drilled and evaluated by attending-level working group members using an 15-question Likert scale questionnaire. The models were graded on anatomic accuracy as well as their suitability as a simulation of both cadaveric and operative temporal bone drilling.
The models produced for this study demonstrate significant anatomic detail and a likeness to human cadaver specimens for drilling and dissection. Models printed in standard resin material with a stereolithography printer scored highest in the evaluation, though the margin of difference was negligible in several categories.
Simulated 3D temporal bones created through a number of printing methods have potential benefit in surgical training, preoperative simulation for challenging otologic cases, and the standardized testing of temporal bone surgical skills.
美国耳鼻喉科学-头颈外科学会基金会（AAO-HNSF）的 3D 打印颞骨工作组的成立目标是分享与开发 3D 打印颞骨模型相关的信息和经验。该小组进行了一项多机构研究，以直接比较几种最近开发的模型。

工作组于 2018 年召开会议。然后共享和记录了以各种方式创建和打印 3D 虚拟模型的方法，以便比较每种方法的优缺点和成本。此外，在 2018 年 10 月的 AAO-HNSF 年会上举行了一次钻孔活动。每个模型都由参加会议的工作组成员使用 15 个问题的李克特量表问卷进行钻孔和评估。根据解剖学准确性以及作为尸体和手术颞骨钻孔模拟的适用性对模型进行评分。
本研究中制作的模型展示了显著的解剖细节，并且在钻孔和解剖方面与人体尸体标本相似。使用立体光刻打印机打印的标准树脂材料模型在评估中得分最高，尽管在几个类别中差异很小。
通过多种打印方法创建的模拟 3D 颞骨在手术培训、有挑战性的耳科病例的术前模拟以及颞骨手术技能的标准化测试方面具有潜在的益处。
