Thirteen subjects had intraoperative compound cochlear action potentials measured to assess vibroplasty coupling during and after surgery. In these patients, surgery was modified according to electrocochleographic feedback.

Compound action potential recordings indicated specific surgical modalities to optimize coupling of the floating mass transducer with the round window membrane.
