“…Indeed studies published so far agree about the poorer performances of prelingually deafened adolescents or adults compared to postlingually deafened or early implanted subjects [Bassim et al, 2005;Manrique et al, 1999;Schramm et al, 2002;Snik et al, 1997;Teoh et al, 2004a;Waltzman et al, 2002]. Nevertheless, different degrees of improvement in speech perception scores on closed-set tests have been reported by various studies, while openset speech recognition performances vary from null to a moderate increase after cochlear implantation.…”

Cochlear Implantation Outcome in Prelingually Deafened Young Adults

The outcome of cochlear implantation in patients with deafness of prelingual onset is largely unpredictable due to high individual variability. This study evaluated speech perception performances in a group of 18 prelingually deafened subjects (aged 13–30 years) which was homogeneous with respect to duration of deafness, hearing aid use before cochlear implantation, mode of communication and administration of auditory-oral speech therapy. Word discrimination length, word and sentence identification, phoneme identification and word and sentence recognition were tested before cochlear implantation and at 6 months, 1, 2 and 3 years of cochlear implant use. Scores on all tests significantly improved after cochlear implantation, although mean values were lower compared to those achieved by postlingually deafened patients. Speech performances on both word and sentence recognition continued to increase over time also beyond 1 year after cochlear implantation. Moreover, scores on sentence recognition tests were significantly higher compared to disyllabic words at 3 years of cochlear implant use. The presence of an auditory input delivered by hearing aids before cochlear implantation associated with auditory-oral therapy and a good level of education may positively influence the cochlear implant outcome in prelingually deafened adults.

Cochlear Implantation Outcome in Prelingually Deafened Young Adults

“…The early studies of adult recipients with prelinguistic hearing loss showed only limited improvement in speech perception skills after implantation [Dawson et al, 1992;Skinner et al, 1992;Waltzmann et al, 1992;Zwolan et al, 1996]. More recent research, however, has found a greater range of improvement, with the considerable variability in outcome partly explained by differences in duration of hearing loss and age at time of implantation [Sarant et al, 1994;Schramm et al, 2002;Teoh et al, 2004;Waltzmann and Cohen, 1999]. Among postlinguistically deafened adult CI recipients, the strongest predictors of success appear to be age at onset of hearing loss [Kaplan et al, 2003], duration of hearing loss [Blamey et al, 1996;Geier et al, 1999;Hamzavi et al, 2003, Oh et al, 2003Shea et al, 1990; UK Cochlear Implant Study Group, 2004] and age at implantation [Blamey et al, 1996;Tyler and Summerfield, 1996].…”

This study investigated whether cognitive measures obtained prior to cochlear implant surgery activation could predict improvements in spoken word recognition in adult cochlear implant recipients 6 months after activation. In addition to noncognitive factors identified by previous studies (i.e. younger age, shorter duration of hearing loss), the present results indicated that improvement in spoken word recognition was associated with higher verbal learning scores and better verbal working memory. Contrary to expectation, neither general cognitive ability nor processing speed was significantly correlated with outcome at 6 months. Multiple regression analyses revealed that a combination of verbal learning scores and lip-reading skill accounted for nearly 72% of the individual differences in improvement in spoken word recognition (i.e. the variance in spoken word recognition scores at 6 months that remained unexplained after controlling for baseline spoken word recognition scores). These findings have relevance for research on auditory processing with cochlear implants as well as implications for clinical interventions.

“…The research that is available focused mainly on audiological outcomes. Improvements such as an increased awareness of environmental sounds, better speech discrimination and better speech perception without lip-reading have all been reported, including in those teenagers who were pre-lingually deafened (Kiefer et al, 1996;Schramm et al, 2002;Sarant et al, 1994). This is encouraging since prelingual deafness (being deafened before language is acquired) can be associated with poorer outcomes compared with post-lingual deafness, if there is a delay in implanting the child.…”

“…The speech and language abilities of pre-lingually deafened teenagers were reported to be good following implantation in early adolescence (Kiefer et al, 1996;Schramm et al, 2002;Sarant et al, 1994). However, there is variation between individuals and very small numbers of adolescents were studied which makes it difficult to assess how representative these conclusions are.…”

“…However, there is variation between individuals and very small numbers of adolescents were studied which makes it difficult to assess how representative these conclusions are. The conclusions are also limited by possible learning effects and participants not understanding the task, although Schramm et al (2002) used both quantitative (speech recognition tests) and qualitative measures (self-report questionnaire rating speech perception)…”

Whilst much research has focused on the general health needs of adolescents, little is known about the specific needs of teenagers who wear cochlear implants. Thus it is important to widen the knowledge base regarding the experiences of this population, and to assist professionals to support this age group more effectively.This qualitative study investigated teenage cochlear implant users' perceptions of deafness, surgery, fitting of the device and life as a cochlear implant wearer in order to gain a more comprehensive understanding of teenagers' experiences of living with a cochlear implant by putting their perspectives at the heart of the research. This was achieved by working with the teenagers collaboratively throughout the research.Phase one of the study involved engaging with a small group of teenagers with cochlear implants to develop a website that would allow them to share their experiences. In phase two, ten semi-structured interviews were undertaken and nine were analysed using template analysis. Some teenagers experienced great preoperative anxiety and significant post-operative pain. Anxiety and pain are physiologically linked so strategies for reducing their anxiety are discussed. There was also a mismatch between their expectations and the disappointing reality of adjusting to the device. Disconfirmation-expectancy theory suggests that expectations counselling may narrow this gap. However, over time they experienced significant functional and psychosocial benefits as a result of their lives being easier. Almost all described complex, flexible identities where they felt connections with both the hearing and deaf world. Theoretical models of deaf identity support this 'bicultural' state. However, the hearing world sometimes posed difficulties for them when the listening environment was challenging. By giving prominence to the teenagers' voices this study has added new knowledge concerning their experience of surgery. The findings also more fully revealed the challenges of adjusting to the device and the impact of having a cochlear implant on the teenagers' identities.ii iii
