Overview

Prospective trial assesses postoperative cochlear health monitoring, indicating biomarkers for hearing outcomes.

Key Points

  • This study aims to understand postoperative residual hearing loss mechanisms and evaluate cochlear health monitoring tools.
  • Conducted a prospective clinical cohort investigation with 32 subjects.
  • Utilized patient-administered in-home monitoring of electrocochleography and four-point impedance over three months.
  • Assessed correlations between ECochG markers, CM amplitude, and hearing preservation outcomes.
  • ECochG markers correlated with poorer hearing preservation (mean scores: 56.88% vs. 38.91%, p = 0.0328).
  • In-home monitoring detected significant drops in CM amplitude associated with poorer outcomes (mean loss: 31.45 dB vs. 11.78 dB, p = 0.0003).
  • Recorded higher impedances linked to reduced hearing preservation (peak median 4PI: 398.46 Ω vs. 270.75 Ω, p = 0.0478).
