Analysis of the Effects of Temporal Factors on Electrically Evoked Auditory Middle Latency Response after Cochlear Implantation in Auditory Remodeling
To study the temporal factors affecting the electrically evoked auditory middle latency response (EMLR) after cochlear implantation
including age at implantation
post-implantation duration
and present age
in order to investigate the effects of different temporal factors in the process of auditory remodeling.
Methods
2
Forty-six patients who underwent cochlear implantation at the ENT Department
Peking University Third Hospital between 2008 and 2014 were tested for EMLR after surgery. Differences in EMLR between pre-lingual children and post-lingual adults were compared
as well as the effects of temporal factors such as present age
age at implantation
and post-implantation duration on EMLR in pre-lingual children.
Results
2
The latencies and intervals were generally longer and the inter-peak amplitudes were generally larger in the pre-lingual children than in the adults
with statistically significant differences (
P
<
0.05) in Po
Na
Pa
Nb
and Pb latencies
PoNa
NaPa
and PaNb intervals
and PoNa
NaPa
PaNb
and NbPb inter-peak amplitudes on EMLR. In pre-lingual children
Pa and Nb latencies and NaPa intervals showed significant negative correlations with present age and post-implantation duration
and positive correlations with age at implantation (
P
<
0.05).
Conclusion
2
There were significant differences in EMLR between pre-lingual children and post-lingual adults. In pre-lingual children
older age
longer post-implantation duration
and younger age at implantation corresponded to more mature EMLR waveforms
suggesting the importance of the above factors in the process of auditory remodeling.
