Analysis of Long-Term Effect of Bimodal Intervention in Children with Hearing Loss
To investigate the bimodal intervention (cochlear implant (CI) on one side and hearing aid (HA) on the other side) in children with bilateral profound hearing loss (HL) and its influencing factors
and evaluate the long-term effect of bimodal intervention(BI).
Methods
2
103 children with preoperative diagnosis of bilateral profound HL
unilateral CI and the time of postactivation more than 5 years were recruited
including 63 males and 40 females. The average age of CI implantation was 1.5±0.6y and the average postactivation time was 8.3 ± 2.6y. To investigate the use of HA on the contralateral side after operation
including whether the contralateral ear had worn HA after operation
the reasons why they had not worn HA
and whether they insisted on wearing HA. A total of 11 cases who still insisted on wearing HA were taken as the experimental group (BI group). Another 11 cases without HA
with the matched residual hearing in the non-implanted ear
the experience of CI
gender and age
were taken as the control group (CI group). The mandarin hearing in noise test (M-HINT) was used to evaluate the speech recognition ability of subjects under noise. Three modes were set during the test: the fixed speech sound came from the front
and the noise came from the front
CI side and non-implant side respectively.
Results
2
63 patients (61.17%) never wore HA after CI
mainly due to the poor performance of HA (50.79%); 40 people (38.83%) had worn HA on the opposite side
and only 21 people (20.39%) still insist on wearing HA; For subjects who insisted on wearing HA
the average performance in BI modes was 27.62% higher than that in CI alone mode. The average speech recognition threshold of M-HINT in BI group was lower than that in CI group
but there was no significant difference between the two groups (
P
>
0.05).
Conclusion
2
For those children with bilateral profound HL
it is recommended to wear HA on the contralateral ear after unilateral CI when they cannot have bilateral CI due to various reasons. However
if there is no residual hearing on the contralateral ear
