Assessment of telephone speech perception in individuals who received cochlear implant in the period 1993-2003 / Avaliacao da percepcao de fala ao telefone em individuos que receberam o implante coclear no periodo de 1993 a 2003

OBJECTIVE: To evaluate telephone speech perception in individuals who received cochlear implant in the period 1993-2003. METHODS: Twenty seven CI users were divided into pre and post-lingual groups, being the speech perception assessed in two stages: first by a list of sentences imposed on speakerphone with the same mapping used to evaluate the phone and, in a second stage, using the landline, landline phone adapter with CI and cell phone. RESULTS: In the group of pre-lingual hearing loss, 75% of subjects were able to maintain a dialogue with the interlocutor and 19% did so with difficulty. In the post-lingual group, 89% were able to maintain the dialogue with the interlocutor and 11% did so with difficulty. Both groups of subjects pre and post-lingual use the phone as a media, and most have satisfactory performance without the need for aid or CI accessories. CONCLUSION: One of the benefits of the CI is to introduce the life of the hearing impaired phone use regardless of their technology and accessories, as well as with the phone adapter and cell phone. In this study, most individuals CI users showed satisfactory performance in the comprehension of sentence and questions by the telephone, with better performance, although discrete, for the group post-lingual. Thus, there is the importance of careful indication of the IC and auditory rehabilitation program that minimize the impact of deafness in the communication, especially via telephone, regardless of the time when the hearing was acquired. So, this fact improves the conditions for CI users to maintain their daily activities, following the dynamism of contemporary life. .

OBJETIVO: Avaliar a percepção de fala ao telefone em indivíduos que receberam o implante coclear multicanal no período de 1993 a 2003. MÉTODOS: Vinte e sete usuários de IC foram divididos em grupos pré e pós-lingual, sendo que a percepção de fala foi avaliada em dois momentos: primeiramente por uma lista de sentenças aplicada a viva-voz com o mesmo mapeamento utilizado na avaliação ao telefone e, em um segundo, utilizando-se o telefone fixo, telefone fixo com adaptador para IC e telefone celular. RESULTADOS: No grupo de deficiência auditiva pré-lingual, 75% dos indivíduos foram capazes de manter o diálogo com o interlocutor e 19% o fizeram com dificuldade. Já no pós-lingual, 89% foram capazes de manter o diálogo com o interlocutor e 11% o fizeram com dificuldade. Tanto os indivíduos dos grupos pré quanto os do pós-lingual utilizam o telefone como meio de comunicação, e a maioria apresenta desempenho satisfatório sem a necessidade de auxílio ou acessórios do IC. CONCLUSÃO: Um dos benefícios do IC é introduzir na vida do deficiente auditivo o uso do telefone independente de sua tecnologia e acessórios, bem como o telefone com adaptador e o celular. Neste estudo, a maioria dos indivíduos usuários de IC apresentou desempenho satisfatório de compreensão de sentenças e perguntas ao telefone, com melhor desempenho, apesar de discreto, do grupo pós-lingual. Desta forma, verifica-se a importância da indicação criteriosa do IC e do programa de reabilitação auditiva, que minimizam os prejuízos da surdez na comunicação, principalmente via telefone, independente do momento no qual a deficiência auditiva foi adquirida. Assim, melhoram-se as condições para os usuários de IC manterem suas atividades ...

[Assessment of speech and linguistic disorders in patients with cochlear implant--preliminary results]. / Ocena mowy i zaburzen jezykowych u chorych z implantem slimakowym--doniesienie wstepne.

UNLABELLED: Cochlear Implant (CI) is the most advanced technical solution in the treatment of profound hearing loss and deafness in patients of all age groups. The aim of the study was to analyse the speech and linguistic disorders in adults with pre- and postlingual deafness rehabilitated with Cochlear implant (CI). MATERIAL AND METHODS: 21 adults with pre- (I group) and postlingual (II group) deafness deriving no benefit from hearing aids participated in this study. Phonatory organ was examined by endoscopy (VLS) and stroboscopy (VLSS). Test of Auditory Perception (TSS) was conducted directly after the activation of speech processor and after rehabilitation. The logopedic assessment before and after CI was based on the examination of motoric activity of articulatory organs, type of respiration, loudness of speech and the assessment of articulation. The linguistic assessment of grammatical and lexical aspect was carried out. The prosodic elements of speech were also analysed. RESULTS: Stroboscopic examination pointed to hypofunction of larynx in patients with prelingual deafness and hyperfunction--in postlingual deafness. The values of TSS were improved after CI, especially in patients with postlingual deafness. The most severe disorders of the efficiency of articulatory organs were observed in patients with prelingual deafness before CI. In the group of prelingually deaf patients disorders of the articulation of vowels and consonants as well as the lexical and grammatical aspect of speech were improved after CI. The correctness of syntax and inflection, development of active vocabulary, improvement of prosodic elements of speech were noticed in patients with postlingual deafness after CI. CONCLUSIONS. Patients with postlingual deafness achieved better results of rehabilitation in auditory perception than prelingually deaf patients. The linguistic improvement of grammatical and lexical aspect was noticed especially in prelingually deaf patients after implantation. This group of patients achieved also the significant progress in prosodic elements of speech in comparison with the results before implantation.

Criteria of candidacy for unilateral cochlear implantation in postlingually deafened adults I: theory and measures of effectiveness.

OBJECTIVES: The objectives of this study were to distinguish the equivalent-effectiveness, health-economic, and actuarial approaches to specifying criteria of candidacy for medical interventions; to apply the equivalent-effectiveness approach to unilateral cochlear implantation for postlingually deafened adults; and to determine whether the criterion should take age at implantation and duration of profound deafness into account. DESIGN: The study was designed as a prospective cohort study in 13 hospitals with four groups of severely-profoundly hearing-impaired subjects distinguished by their preoperative ability to identify words in sentences when aided acoustically. The groups represent a progressive relaxation of criteria of candidacy: Group I (N=134) scored 0% correct without lipreading and did not improve their lipreading score significantly when aided; group II (N=93) scored 0% without lipreading but did improve their lipreading score significantly when aided; group III (N=53) scored 0% without lipreading when the to-be-implanted ear was aided but between 1% and approximately 50% when the other ear was aided. Group IV (N=31) scored between 1% and approximately 50% without lipreading when the to-be-implanted ear was aided. Measures of speech intelligibility, health utility, and otologically relevant quality of life were obtained before surgery and 9 mo after surgery from each subject. Measures of effectiveness were calculated as the difference between 9-mo and preoperative scores. RESULTS: Effectiveness differed only slightly between groups. Effectiveness was not strongly associated with age at the time of implantation. Greater effectiveness was associated with implantation in the ear with the shorter duration of profound deafness. Cochlear implantation was least effective when the preoperative audiological status of the better-hearing ear was good and the duration of profound deafness of the implanted ear was long. As a result, effectiveness was not significant for the subsets of groups III and IV, who were given implants in ears that had been profoundly deaf for more than 30 yr. CONCLUSIONS: The effectiveness of cochlear implantation differs little between groups of candidates who score zero with acoustic hearing aids before surgery and groups who score up to approximately 50% correct, thereby justifying a relaxation of the criterion of candidacy to embrace some members of the latter groups. The criterion should be based not only on preoperative speech intelligibility but also on duration of profound deafness in the to-be-implanted ear.

Controlling the quality of universal neonatal hearing screens.

The Health Technology Assessment Programme has recently reviewed the role of neonatal screening in the detection of congenital hearing impairment. The review recommends that the health visitors distraction screen, currently implemented in the second half of infancy, should be replaced by a national programme based around universal neonatal hearing screening. Such a programme has been implemented as a routine and established service in Whipps Cross Hospital in the East London district of Waltham Forest. This programme has reinforced the need to routinely monitor the screen processes and outcomes. The Whipps Cross audit undertaken over a 2 y period from January 1996 is detailed, as are the targets employed for evaluating the processes. The monitoring flagged up implementation problems, and allowed remedial intervention. Monitoring should be built into all the universal neonatal hearing programmes currently being planned in the UK.
