Natural variations in cochlear anatomy have substantial implications for both clinical care and research in the fields of otology, neurotology, and audiology. While precise anatomic characterization is essential for a multitude of applications, comprehensive reference dimensions of both osseous and membranous cochlear structure obtained from a large and morphologically heterogeneous sample set do not currently...
These normative cochlear morphometry values provide a useful anatomical reference for surgical planning and cochlear implant electrode design, but do not yet require changes to routine clinical practice pending validation in surgical outcome studies.
High-precision normative cochlear anatomy data underpins safer cochlear implant surgery, better electrode array design, and improved patient-specific fitting strategies.
- 01Synchrotron imaging provides sub-micron resolution measurements of cochlear anatomy not achievable with standard CT.
- 02The study establishes normative reference values capturing natural anatomical variation across specimens.
- 03Data are directly relevant to cochlear implant electrode design and surgical insertion planning.
- 04The compendium format is intended as a shared resource for the otology and audiology research community.
- 05Findings may inform the development of patient-specific or morphology-guided fitting protocols.
Synchrotron-based measurements provide high-resolution normative cochlear morphometry values characterising natural anatomical variation.
