OBJECTIVE: To assess the safety and the possible advantages of early (1-wk) cochlear implant switch-on in children and to compare impedance and ECAP threshold changes between subjects undergoing early switch-on and those undergoing traditional, 1-month switch-on.
STUDY DESIGN: Prospective cohort study.
SETTING: Tertiary care referral pediatric center.
PATIENTS: Seventeen children receiving a unilateral or bilateral Nucleus Freedom cochlear implant were included, for a total of 20 ears. Ten ears were assigned to the early (1-wk) switch-on group and 10 to the control group (switch-on after 4 wks).
INTERVENTIONS: Common ground impedance values and electrically evoked compound action potential thresholds were measured from intraoperation until 9 months postoperatively. Speech perception improvements over time were also assessed.
MAIN OUTCOME MEASURES: Complication rate, impedance levels (kΩ), and electrically evoked compound action potentials (current levels)
RESULTS: Early switch-on was well tolerated by patients and did not cause complications. Impedances dropped significantly after switch-on in both groups. They also seemed to achieve an earlier stability in the early switch-on patients, although the difference between groups was not significant. ECAP thresholds showed a similar, nonsignificant decreasing trend over time in both groups. Speech perception improvements did not differ between groups.
CONCLUSION: This is the first study investigating the safety and the effects of an early cochlear implant switch-on in children. Results show that such a procedure is well tolerated by pediatric subjects and free from complications. Impedance measurements suggest that the earlier switched-on subjects benefit of lower and more stable impedances than subjects undergoing 1-month switch-on.
