Objective

2

To compare the clinical efficacy of bilateral cochlear implantation and bimodal intervention in the treatment of young patients with prelingual hearing loss.

Methods

2

The clinical data of 88 young children with presyllabic deafness admitted to our otorhinolaryngology head and neck surgery department from July 2019 to June 2021 were analyzed retrospectively. According to the different intervention methods

they were divided into Group A (n=45) and group B (n=43). Children in Group A received bilateral cochlear implant intervention

while children in Group B received unilateral cochlear implant intervention and contralateral hearing aid intervention. The children's hearing and speech perception ability were evaluated with the Integrated Meaningful Auditory Scale for Infants (IT-MAIS) and the Simplified Mandarin Early Speech Perception Test (LV-MESP) before

6 months and 12 months after switch-on. The children's hearing and speech perception abilities were evaluated with the Speech Space Hearing Quality Scale Parent Parent Version Questionnaire (SSQ-P)

and the children's quality of life was evaluated with the Chinese version of CI Children's Parent Opinion Questionnaire (MPP).

Results

2

The percentage of IT-MAIS score and LV-MESP score in Group B were significantly higher than those in Group A at 6 months of boot (

P

<

0.05)

but there was no significant difference between the two groups at 12 months of boot (

P

>

0.05). The spatial hearing and hearing quality dimension scores of children in Group B were significantly higher than those in Group B after 6 months of boot (

P

<

0.05). There was no significant difference between the two groups in speech perception dimension scores at different times and spatial hearing and hearing quality dimension scores at 12 months of boot (

P

>

0.05). There was no significant difference between Group A and Group B in all dimensions of the MPP scale at 12 months (

P

>

0.05).

Conclusion

2

The short-term effect of bimodal intervention is slightly better than that of bilateral cochlear implantation in the treatment of young children with prelingual deafness

but the long-term effect of the two interventions is similar.Clinical selection should be made according to the surgical risk

whether the child is symmetrical deafness

and the family economic situation.
