Abstract

Study design: Face and content validation of a surgical simulation model.

Objective: Open reduction and internal fixation in displaced subcondylar mandibular fractures is standard care. This requires an extraoral (eg: retromandibular, transparotideal) or intraoral approach. An intraoral approach requires further training since specialized instrumentation such as the 90° screwdriver system and endoscopes might be needed. Currently, no simulation models are available for training residents in intraoral reduction and fixation of subcondylar mandibular fractures. Therefore, we present a validated simulation model for intraoral treatment of subcondylar mandibular fractures.

Methods: Based on a computer tomography data set, we designed and printed a 3D model of a mandible with a unilateral subcondylar fracture. To simulate intraoral work depth, it was positioned inside a dental phantom. We tested the model by a group of experts (n = 8), simulating intraoral reduction and fixation of a unilateral subcondylar fracture, using a 90° screwdriver system, a 1.0 subcondylar plate (lambda), and 5-6 mm screws.We assessed Face and Content validity by survey.

Results: We provided an open-source printable fracture model. Printing costs were approximately US $10. Experts "Agreed" the model resembling the real scenario and its use for training intraoral reduction and fixation of subcondylar mandibular fractures.

Conclusions: We developed a low cost, reproducible, open-source simulator for subcondylar mandibular fractures. Face and Content validity was achieved through evaluation by a group of experts.

用口内切开复位和内固定模拟下颌髁下骨折:一种新的居民教育工具。
研究设计:手术模拟模型的面部和内容验证。目的:切开复位内固定治疗移位的下颌髁下骨折是标准的治疗方法。这需要口外入路(如:下颌骨后、经鼻窦)或口内入路。口腔内入路需要进一步的培训,因为可能需要专门的器械,如90°螺丝刀系统和内窥镜。目前,没有模拟模型可用于培训住院医师进行下颌髁下骨折的口内复位和固定。因此,我们提出了一个有效的模拟模型,用于下颌髁下骨折的口腔内治疗。方法:基于计算机断层数据集,设计并打印单侧髁下骨折的下颌骨三维模型。为了模拟口腔内工作深度,将其放置在牙模内。我们由一组专家(n = 8)对模型进行了测试,使用90°螺丝刀系统、1.0髁下钢板(lambda)和5-6 mm螺钉模拟单侧髁下骨折的口内复位和固定。我们通过问卷调查来评估Face和Content效度。结果:我们提供了一个开源的可打印骨折模型。印刷费用约为10美元。专家“同意”该模型与真实场景相似,并将其用于训练下颌髁下骨折的口内复位和固定。结论:我们开发了一个低成本、可重复、开源的下颌髁下骨折模拟器。面孔效度和内容效度由专家小组评定。

期刊介绍: Complementary Therapies in Medicine is an international, peer-reviewed journal that has considerable appeal to anyone who seeks objective and critical information on complementary therapies or who wishes to deepen their understanding of these approaches. It will be of particular interest to healthcare practitioners including family practitioners, complementary therapists, nurses, and physiotherapists; to academics including social scientists and CAM researchers; to healthcare managers; and to patients. Complementary Therapies in Medicine aims to publish valid, relevant and rigorous research and serious discussion articles with the main purpose of improving healthcare.
