Objective measurement of auditory perception in pediatric cochlear cases by near-infrared spectroscopy (NIRS)

As the objective measure for auditory perception in small children is limited, usefulness of NIRS was evaluated in pediatric cochlear implant (CI) cases when their devices were switched on. Of nine children who participated in the study, two wore Nucleus 24 and seven Clarion-S. Gneders were five boys and four girls. The mean age was 5.0 y.o. (ranged from 3.3 to 8.3 y.o) The NIRS system of Shimazu Co. Ltd. (OMM-2001, Kyoto/Japan) was used. It consists of three light emitting and three light receiving probes, which were attached on the temporal region on the opposite side of CI. Changes of oxidized (oxy-Hb), deoxi…
