Temporal bone dissection is overwide recognized as an ideal training method for otologic surgeons. The knowledge of temporal bone anatomy and especially of the course of infratemporal facial nerve is pivotal in practice. The 3D exoscope is an innovative and promising tool, that was recently introduced in ear surgery.
A high-definition 3D exoscope (3D VITOM®) mounted on the VERSACRANE holding system (Karl Storz) was used to perform two temporal bone dissection, with the aim to study the anatomy of infratemporal facial nerve. The 3D endoscope (TIPCAM®1 S 3D ORL, Karl Storz) was used in combination to provide a close-up high-quality view and to provide a different angle of view on fine anatomical relationships.
The high-definition 3D exoscope allowed to conduct the dissection with high quality visualization and to share the same surgical field with trainees. Moreover, it showed a high interchangeability with the 3D endoscope.
3D 4 K Exo-endoscopic temporal bone dissection seems to have benefits in terms of educational purpose, especially concerning anatomy understanding. The superiority in teaching value of this tool should be further investigated in cohort studies.
颞骨解剖被广泛认为是耳科医生的理想培训方法。颞骨解剖学知识，特别是面神经在颞骨内的走行，在实践中至关重要。3D 手术显微镜是一种创新且有前途的工具，最近已被引入耳科手术中。
使用高清 3D 手术显微镜（3D VITOM®）安装在 VERSACRANE 持镜系统（Karl Storz）上，进行两次颞骨解剖，旨在研究面神经在颞骨内的解剖结构。同时使用 3D 内镜（TIPCAM®1 S 3D ORL，Karl Storz）提供特写的高质量视图，并提供精细解剖关系的不同视角。
高清 3D 手术显微镜可实现高质量的可视化效果，并可与学员共享同一手术视野。此外，它与 3D 内镜具有很高的互换性。
3D 4K 外-内镜颞骨解剖在教学目的方面具有优势，尤其是在解剖理解方面。应进一步在队列研究中探讨该工具在教学价值方面的优越性。
