Ear & Hearing VOL. 39, NO. 3, 401–411 (2017)Abstract: Objectives: The electrically evoked compound action potential (eCAP)
is widely used in the clinic as an objective measure to assess cochlear
implant functionality. During the past decade, there has been increasing
interest in applying eCAPs for fitting of cochlear implants. Several
studies have shown that eCAP-based fitting can potentially replace timeconsuming
behavioral fitting procedures, especially in young children.
However, a closer look to all available literature revealed that there is
no clear consensus on the validity of this fitting procedure. This study
evaluated the validity of eCAP-based fitting of cochlear implant recipients
based on a systematic review of the recent literature.
