Introduction: Early stimulation of the auditory
sense is essential for the development of language and speech. In children with a cochlear implant, the most common issue is whether the hearing has been optimized or not, as
they are still unable to provide reliable feedback regarding their hearing
ability. Thus, electrically evoked stapedius reflex threshold (ESRT)
based fitting has been used as one of the available methods in programming a cochlear
implant (CI) audio processor. As eSRT is an objective test, patient cooperation
was not needed making it especially beneficial for children with CI who have
limitations in providing feedback. Now that eSRT has been applied commonly almost
worldwide, the goal of this study is to determine the normative value of eSRT
among the pediatric population in Indonesia. Methods: A total of 32
pediatric CI users inthe age range 3 - 11 years implanted with Med-El cochlear implant were included in this
study. ESRT was performed during follow-up mapping between September 2021 and
January 2022 in the Med-El Indonesia hearing center.Results: The result of the present study showed an average
normative value of 20.55 qus. This finding is consistent with the values
obtained in previous studies. Conclusion: The result
