4.1 Strength and limitation
This is the largest study so far documenting to evaluate and compare the
auditory perception performance of children with IEM, and normal
cochlear anatomy is one of the strengths.Secondly, all subjects with
different ear anomaly that provided maximum and minimum benefit from CI
were considered and ranked.Thirdly, the present study adds to the
growing body of research that indicates auditory perception performance
of children with various IEMs to determine the expectation after
cochlear implantation. This study was limited by the absence of language
evaluation in the control group. In future studies, both groups can be
compared in terms of language performance.
