Abstract

Temporal-bone milling is a delicate process commonly performed during otologic surgery to gain access to the middle and inner ear structures. Because of the numerous at-risk structures of this anatomic area, extensive surgeon training is required. Artificial temporal bones offer an interesting alternative to cadaveric training. However, the evaluation of such simulators has not been systematic, with an absence of objective validation of their milling response, especially in a surgical context.

By measuring the milling forces obtained during the classical steps of otologic surgery on six 3D-printed and three cadaveric temporal bones, this work aims at evaluating the ability of the OTOtwin® synthetic temporal bone to reproduce human bone behavior.

A better repeatability was obtained for artificial bones than for cadaveric ones. However, the level of forces recorded during artificial bone milling was close to the one measured with cadaveric samples. The effects of both surgical phase and irrigation on milling force levels were also quantified. The experiments conducted in this study confirmed the suitability of OTOtwin® temporal bone model for both otologic surgery training and research purposes. Valuable insights were also gained from this study regarding the understanding of the otologic milling process.

用于耳科手术的人工颞骨的铣削反应分析与人体样本的比较
颞骨铣削术是耳科手术中常见的精细过程,目的是进入中耳和内耳结构。由于这一解剖区域的风险结构众多,因此需要对外科医生进行广泛的培训。人工颞骨为尸体训练提供了一个有趣的替代方案。通过测量耳科手术经典步骤中在六块三维打印颞骨和三块尸体颞骨上获得的铣削力,这项工作旨在评估 OTOtwin® 合成颞骨再现人体骨骼行为的能力。然而,人工骨铣削过程中记录的力水平接近于尸体样本的测量值。此外,还量化了手术阶段和灌洗对铣削力水平的影响。本研究中进行的实验证实了 OTOtwin® 颞骨模型适用于耳科手术培训和研究目的。本研究还在了解耳科铣削过程方面获得了宝贵的见解。
