Influence of the Spread of the Electric Field on Speech Recognition in Cochlear Implant Users
Copyright © 2023, Otology & Neurotology, Inc..
OBJECTIVE: To investigate the correlation of word recognition with cochlear implant (CI) and spread of the electric field.
STUDY DESIGN: Prospective, noninterventional, experimental study.
SETTING: A tertiary referral center.
PATIENTS: Thirty-eight adult CI users with poor (n = 11), fair (n = 13), and good (n = 16) word recognition performance.
MAIN OUTCOME MEASURE: Transimpedances were measured after 37 μs. Word recognition score was recorded at 65 dB SPL for German monosyllables in quiet. Transimpedance half widths were calculated as a marker for spread of the electric field.
RESULTS: Narrow and broad spread of the electric field, i.e., small and large half widths, were observed in all word recognition performance groups. Most of the transimpedance matrices showed a pattern of expansion along the diagonal toward the apical electrode contacts. Word recognition was not correlated with transimpedance half widths.
CONCLUSIONS: The half width of the spread of the electric field showed no correlation with word recognition scores in our study population.
