Background

Cochlear duct length (cochlear duct length) varies between individuals and influences cochlear implant (CI) electrode selection, making proper preoperative measurement an important step for optimizing CI outcomes.

Purpose

To measure and report cochlear duct length and the cochlear parameters in subjects who underwent temporal bone CT scan in Bahrain.

Methods

This retrospective cohort study evaluated temporal bone CT scans obtained between 2010 and 2022 at Governmental Hospitals in Bahrain.

Results

34.8

± 1.7 mm

males had larger cochlear measurements than females

More results

Of the 200 ears analyzed, 142 met the inclusion criteria.

Males showed significantly larger cochlear measurements than females, whereas no significant differences were observed between pediatric and adult subjects or between right and left ears.

“

Conclusion · 1 of 2

Cochlear duct length varies significantly by gender but not by age or side.

Conclusion · 2 of 2

Differences were also observed between the Bahraini population and certain other geographic populations, highlighting the importance of individualized preoperative cochlear duct length measurement to optimize electrode array selection and CI outcomes.
