Abstract

Congenital microtia manifests abnormalities in the external ear leading to potential adverse impacts on psychosocial health and hearing impairment. Three-dimensional (3D) technologies have demonstrated potential applications for personalised prosthesis fabrication; however, the large hardware costs limit their routine clinical use. Frugal 3D scan-model-print pipelines can disrupt traditional processes and increase accessibility. In this study, we aimed to further validate 3D photogrammetry using 3 different smartphone models. Both ears of 10 participants were scanned with 4 devices: Samsung Galaxy S8, Samsung Galaxy S9, Apple® iPhone 8S, and Artec Spider 3D scanner. Scan, processing times, accuracy, completeness, and repeatability of the smartphone models were analysed with no significant difference across all tested models (Accuracy: 1.1 ± 0.3 mm, Completeness: 81 ± 10%). This demonstrates a flexibility in capture device selection for smartphone photogrammetry, with the potential to broaden the translation of this frugal 3D scanning approach to personalised prosthesis production.

全面的基于智能手机的外耳三维扫描框架

先天性小耳症表现为外耳异常，导致对心理健康和听力障碍的潜在不利影响。三维（3D）技术已经证明了个性化假肢制造的潜在应用；然而，巨大的硬件成本限制了它们的常规临床应用。节俭的3D扫描模型打印管道可以破坏传统流程并增加可访问性。在这项研究中，我们旨在进一步验证3D摄影测量使用3种不同的智能手机模型。10名参与者的双耳扫描设备分别是：三星Galaxy S8、三星Galaxy S9、苹果®iPhone 8S和Artec Spider 3D扫描仪。对智能手机模型的扫描、处理时间、精度、完整性和可重复性进行分析，所有测试模型之间没有显著差异（精度：1.1±0.3 mm，完整性：81±10%）。这证明了智能手机摄影测量的捕获设备选择的灵活性，有可能扩大这种节俭的3D扫描方法到个性化假肢生产的翻译。
