The purpose of this study was to determine if adolescents with preserved residual low-frequency hearing can develop improved speech perception and maintain localization abilities by combining their acoustic hearing with electrical processing from a short electrode cochlear implant.
Repeated-measure, single-subject experiment.
Research hospital.
Adolescents with sensorineural hearing loss with a pure-tone average (PTA) between 60 and 90 dB HL between 125 and 1500 Hz and profound loss at higher frequencies.
rehabilitative.
Five adolescents received a short electrode cochlear implant in their poorer ear. Audiometric, speech perception in quiet (CNC words), localization, speech production, and language outcomes were collected pre- and postoperatively at 4, 8, 12, and 24 months.
Functional hearing preservation was accomplished in all subjects at initial activation and was maintained through 24 months. In the Combined and Hybrid conditions, all subjects showed significant improvements by 4 months postimplantation, with exception of Subject 2 in the Combined condition, who showed a significant improvement by 8 months postimplantation. Results also indicated that all subjects continue to have localization abilities postimplantation.
All of the subjects have benefitted from the combined electric and acoustic processing for speech perception abilities. The results from this study suggest that it could be worthwhile to consider acoustic and electric hearing in the adolescent population that have some low-frequency residual hearing and are struggling with hearing aids.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 31 August 2016.
All research outputs
#19,944,091
of 25,373,627 outputs
Outputs from Otology & Neurotology
#2,382
of 3,960 outputs
Outputs of similar age
#283,611
of 406,424 outputs
Outputs of similar age from Otology & Neurotology
#47
of 82 outputs
Altmetric has tracked 25,373,627 research outputs across all sources so far. This one is in the 18th percentile – i.e., 18% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,960 research outputs from this source. They receive a mean Attention Score of 3.4. This one is in the 30th percentile – i.e., 30% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 406,424 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 82 others from the same source and published within six weeks on either side of this one. This one is in the 17th percentile – i.e., 17% of its contemporaries scored the same or lower than it.
