“…Emerging research has demonstrated that an ESRT response may be more successfully obtained at a lower stimulus level using a 1,000-Hz probe tone frequency or wideband reflectance compared with a conventional 226-Hz probe tone frequency. 48,49 However, the clinical implications (i.e., relationship of ESRT to C/M level) of these techniques are still unknown.…”

Cochlear implants (CIs) have proven to be a useful treatment option for individuals with severe-to-profound hearing loss by providing improved access to one's surrounding auditory environment. CIs differ from traditional acoustic amplification by providing information to the auditory system via electrical stimulation. Both postlingually deafened adults and prelingually deafened children can benefit from a CI; however, outcomes with a CI can vary. Numerous factors can impact performance outcomes with a CI. It is important for the audiologist to understand what factors might play a role and impact performance outcomes with a CI so that they can effectively counsel the recipient and their family, as well as establish appropriate and realistic expectations with a CI. This review article will discuss the CI candidacy process, CI programming and postoperative follow-up care, as well as considerations across the lifespan that may affect performance outcomes with a CI.

“…Cochlear implant (CI) is a surgically implanted system that electrically stimulates the auditory nerve in individuals with severe to profound hearing loss and who cannot benefit from conventional hearing aids (Wolfe et al, 2016). After surgery, each channel of the CI electrode stimulates the auditory nerve and each patient needs individualized programming of the CI system.…”

“…The electrically stapedius reflex threshold (eSRT) measures are another objective measurement technique that show the upper stimulation levels with the stimulation of the stapes muscle (Wolfe et al, 2016). The eSRT can be used in the determination of the maximum electrical stimulation level both in adults and children (Gordon, Papsin, and Harrison, 2004).…”

“…On the contrary, ESRT is not affected by the same recording restrictions as the eCAP measurements. Stimuli similar to the electrical stimuli used in the programming can be utilized to obtain the ESRT response (Wolfe et al, 2016;Overstreet, 2004).…”

Objectives: During the programming of the cochlear implant (CI) various fitting methods can be used such as electrically stapedial reflex thresholds (ESRT), electrically compound action potential (ECAP) thresholds and behavioral methods with visual loudness scales. The aim of the present study is to investigate the relationship between the eSRT and eCAP thresholds with the behavioral comfortable levels in CI users implanted with CI422. Materials and Methods: Ten CI users included in the study with the mean age of 20.47. Five electrodes were selected from different regions of cochlea for comparison. For these five electrodes, behavioral C (comfortable) levels were determined with Custom Sound 5.2 Fitting Software and eCAP and eSRT thresholds were obtained with Custom Sound EP 5.2. Results: Correlation analysis was done between behavioral C levels and eSRT/eCAP separately. For E22, behavioral C level was positively correlated with eSRT (r=.772; p= .009; p<.01). However, there was no correlational relation with eCAP. For E1, behavioral C level was positively correlated with both eSRT (r=0.785; p=.007; p< .01) and eCAP (r=0.812; p=.004; p<.01). There was not any correlational relation between eSRT levels and eCAP thresholds except for E1. Behavioral C levels was compared with ECAP and ESRT with related-samples Wilcoxon test. The eSRT levels were found significantly higher than the behavioral C levels for all electrodes (p<.05). Conclusion: This study is the first study that investigates the objective measures and behavioral method in CI users with Cochlear CI422 implant. Both eCAP and eSRT levels can be used in CI fitting but eSRT levels are significantly higher than the behavioral C levels. Especially in the basal portion of the cochlea, the C levels are correlated both with eCAP and eSRT levels. It is possible to use both objective thresholds in adjustment of the C levels in basal region in patients with CI422 implant. In order to provide adequate stimulation, the combination of the objective measures and behavioral methods was considered to be the best option.
