The Impact

PurposeThe purpose of this study was to examine the rate of progress in the 2nd implanted ear as it relates to the 1st implanted ear and to bilateral performance in adult sequential cochlear implant recipients. In addition, this study aimed to identify factors that contribute to patient outcomes.MethodThe authors performed a prospective longitudinal study in 21 adults who received bilateral sequential cochlear implants. Testing occurred at 6 intervals: prebilateral through 12 months postbilateral implantation. Measures evaluated speech recognition in quiet and noise, localization, and perceived benefit.ResultsSecond ear performance was similar to 1st ear performance by 6 months postbilateral implantation. Bilateral performance was generally superior to either ear alone; however, participants with shorter 2nd ear length of deafness (<20 years) had more rapid early improvement and better overall outcomes than those with longer 2nd ear length of deafness (>30 years). All participants reported bilateral benefit.ConclusionsAdult cochlear implant recipients demonstrated benefit from 2nd ear implantation for speech recognition, localization, and perceived communication function. Because performance outcomes were related to length of deafness, shorter time between surgeries may be warranted to reduce negative length-of-deafness effects. Future study may clarify the impact of other variables, such as preimplant hearing aid use, particularly for individuals with longer periods of deafness.

PurposeWhether, and if so when, a second-ear cochlear implant should be provided to older, unilaterally implanted children is an ongoing clinical question. This study evaluated rate of speech recognition progress for the second implanted ear and with bilateral cochlear implants in older sequentially implanted children and evaluated localization abilities.MethodA prospective longitudinal study included 24 bilaterally implanted children (mean ear surgeries at 5.11 and 14.25 years). Test intervals were every 3–6 months through 24 months postbilateral. Test conditions were each ear and bilaterally for speech recognition and localization.ResultsOverall, the rate of progress for the second implanted ear was gradual. Improvements in quiet continued through the second year of bilateral use. Improvements in noise were more modest and leveled off during the second year. On all measures, results from the second ear were poorer than the first. Bilateral scores were better than either ear alone for all measures except sentences in quiet and localization.ConclusionsOlder sequentially implanted children with several years between surgeries may obtain speech understanding in the second implanted ear; however, performance may be limited and rate of progress gradual. Continued contralateral ear hearing aid use and reduced time between surgeries may enhance outcomes.

The Impact

When longitudinal studies are performed to investigate the growth of traits in children, the measurement tool being used to quantify the trait may need to change as the subjects’ age throughout the study. Changing the measurement tool at some point in the longitudinal study makes the analysis of that growth challenging which, in turn, makes it difficult to determine what other factors influence the growth rate. We developed a Bayesian hierarchical modeling framework that relates the growth curves per individual for each of the different measurement tools and allows for covariates to influence the shapes of the curves by borrowing strength across curves. The method is motivated by and demonstrated by speech perception outcome measurements of children who were implanted with cochlear implants. Researchers are interested in assessing the impact of age at implantation and comparing the growth rates of children who are implanted under the age of two versus those implanted between the ages of two and four.

Purpose We sought to evaluate the development of grammatical accuracy in English-speaking children with cochlear implants (CIs) over a 3-year span. Method Ten children who received CIs before age 30 months participated in this study at 3, 4, and 5 years postimplantation. For the purpose of comparison, 10 children each at ages 3, 4, and 5 years with typical hearing were included as well. All children participated in a story-retell task. We computed percent grammatical communication units (PGCU) in the task. Results Children with CIs showed significant improvement in PGCU over the 3-year span. However, they produced lower PGCU than children with typical hearing who had matched hearing age at 4 and 5 years postimplantation. At the individual level, some children with CIs were able to produce PGCU comparable to children with typical hearing as early as 3 years after implantation. Better speech-perception skills at earlier time points were associated with higher PGCU at later time points. Moreover, children with and without CIs showed similar rankings in the types of grammatical errors. Conclusion Despite having auditory-perceptual and information-processing constraints, children who received CIs before age 30 months were able to produce grammatical sentences, albeit with a delayed pattern.
