This study investigates the size and shape variation of cochleae in the Russian population. Also, introduces a new cochlear parameter that defines the longest straight segment of the basal turn, with the implication of a safe cochlear implant electrode insertion....
Surgeons and implant teams should note the proposed cochlear parameter as a potential pre-surgical planning aid, but prospective clinical validation is needed before routine adoption.
Reducing the risk of intracochlear trauma during electrode insertion is a persistent challenge in cochlear implantation; population-specific anatomical data could improve surgical precision and implant outcomes.
- 01Study characterizes cochlear anatomy in a Russian population sample, adding to limited non-Western normative data.
- 02A new cochlear morphometric parameter is proposed to guide safer electrode insertion.
- 03Published in Journal of Visualized Experiments (JoVE), suggesting a methodology-focused, reproducible protocol.
- 04Findings may have implications for electrode selection and pre-operative imaging interpretation.
- 05External validation in independent cohorts is required before clinical implementation.
A new cochlear parameter can guide safer electrode insertion during cochlear implant surgery.
