目的 操作性工作流程将操作系统地划分为阶层组件，包括阶段、步骤、仪器、技术错误和事件错误。操作性工作流程为外科变异的教育、培训和理解提供了基础。在本文第二部分中，我们提出了一个用于治疗前庭神经瘤的迷路途径手术性工作流程。方法 我们与英国颅底学会（BSBS）合作进行了文献综述、小组德尔菲共识和全国德尔菲共识的混合方法共识过程。每一轮德尔菲共识在数据饱和和达到90%以上共识之前重复进行。结果 17名顾问颅底外科医生（9名神经外科医生和8名耳鼻喉科医生）参与了独立实践的中位数为13.9年（四分位范围：18.1年）的德尔菲共识过程。在德尔菲共识的两轮中，回应率为100%。迷路途径有以下五个阶段和57个独特步骤：阶段1，途径和暴露；阶段2，乳突切除术；阶段3，内听道和硬膜开放；阶段4，肿瘤减量和切除；阶段5，关闭。结论 我们提出了一项国家多中心共识推导、编码的治疗前庭神经瘤迷路途径手术性工作流程的第二部分。这五个阶段包含了操作、步骤、仪器、技术错误和事件错误。本文所介绍的编码迷路途径手术性工作流程可作为未来研究的基础，例如将人工智能应用于治疗前庭神经瘤以及比较手术研究等。作者：本文是Thieme在Creative Commons Attribution许可下的开放获取文章，允许进行无限制使用、分发和复制，只要原作被正确引用。（https://creativecommons.org/licenses/by/4.0/）。

Objective  An operative workflow systematically compartmentalizes operations into hierarchal components of phases, steps, instrument, technique errors, and event errors. Operative workflow provides a foundation for education, training, and understanding of surgical variation. In this Part 2, we present a codified operative workflow for the translabyrinthine approach to vestibular schwannoma resection. Methods  A mixed-method consensus process of literature review, small-group Delphi's consensus, followed by a national Delphi's consensus was performed in collaboration with British Skull Base Society (BSBS). Each Delphi's round was repeated until data saturation and over 90% consensus was reached. Results  Seventeen consultant skull base surgeons (nine neurosurgeons and eight ENT [ear, nose, and throat]) with median of 13.9 years of experience (interquartile range: 18.1 years) of independent practice participated. There was a 100% response rate across both the Delphi rounds. The translabyrinthine approach had the following five phases and 57 unique steps: Phase 1, approach and exposure; Phase 2, mastoidectomy; Phase 3, internal auditory canal and dural opening; Phase 4, tumor debulking and excision; and Phase 5, closure. Conclusion  We present Part 2 of a national, multicenter, consensus-derived, codified operative workflow for the translabyrinthine approach to vestibular schwannomas. The five phases contain the operative, steps, instruments, technique errors, and event errors. The codified translabyrinthine approach presented in this manuscript can serve as foundational research for future work, such as the application of artificial intelligence to vestibular schwannoma resection and comparative surgical research.The Author(s).
