Automatic Cochlear Duct Length Estimation for Selection of Cochlear Implant Electrode Arrays.

ABSTRACT:

Hypothesis

Cochlear duct length (CDL) can be automatically measured for custom selection of cochlear implant (CI) electrode arrays.

Background

CI electrode array selection can be influenced by measuring the CDL, which is estimated based on the length of the line that connects the round window and the lateral wall of the cochlea when passing through the modiolus. CDL measurement remains time consuming and inter-observer variability has not been studied.

Methods

We evaluate an automatic approach to directly measure the two-turn (2T) CDL using existing algorithms for localizing cochlear anatomy in computed tomography (CT). Pre-op CT images of 309 ears were evaluated. Two fellowship-trained neurotologists manually and independently measured CDL. Inter-observer variability
