An objective cochlear framework, for evaluation of the cochlear anatomy and description of the position of an implanted cochlear implant electrode, would allow the direct comparison of measures performed within the various subdisciplines involved in cochlear implant research.
Research on the human cochlear anatomy in relation to tonotopy and cochlear implantation is conducted by specialists from numerous disciplines such as histologists, surgeons, physicists, engineers, audiologists, and radiologists. To allow accurate comparisons between and combinations of previous and forthcoming scientific and clinical studies, cochlear structures and electrode positions must be specified in a consistent manner.
Researchers with backgrounds in the various fields of inner ear research as well as representatives of the different manufacturers of cochlear implants (Advanced Bionics Corp., Med-El, Cochlear Corp.) were involved in consensus meetings held in Dallas, March 2005, and Asilomar, August 2005. Existing coordinate systems were evaluated, and requisites for an objective cochlear framework were discussed.
The consensus panel agreed upon a 3-dimensional, cylindrical coordinate system of the cochlea using the "Cochlear View" as a basis and choosing a z axis through the modiolus. The zero reference angle was chosen at the center of the round window, which has a close relationship to the basal end of the Organ of Corti.
Consensus was reached on an objective cochlear framework, allowing the outcomes of studies from different fields of research to be compared directly.
一个客观的耳蜗框架，用于评估耳蜗解剖结构和描述植入式耳蜗植入电极的位置，可以允许对涉及耳蜗植入研究的各个子学科中进行的测量进行直接比较。
与音调拓扑和耳蜗植入相关的人类耳蜗解剖学研究是由许多学科的专家进行的，例如组织学家、外科医生、物理学家、工程师、听力学家和放射科医生。为了能够在以前和即将进行的科学和临床研究之间进行准确的比较和组合，必须以一致的方式指定耳蜗结构和电极位置。
在 2005 年 3 月于达拉斯和 2005 年 8 月于阿西洛马举行的共识会议上，参与了具有内耳研究各个领域背景的研究人员以及不同耳蜗植入制造商（Advanced Bionics Corp.、Med-El、Cochlear Corp.）的代表。评估了现有的坐标系，并讨论了客观耳蜗框架的要求。
共识小组同意使用“耳蜗视图”作为基础，采用 3 维圆柱坐标系来描述耳蜗，并选择穿过中轴的 z 轴。零参考角选择在圆窗的中心，圆窗与 Corti 器的基底端密切相关。
就客观耳蜗框架达成了共识，允许直接比较来自不同研究领域的研究结果。
