s, ESPCI 2011 / International Journal of Pediatric Otorhinolaryngology 75 (2011) 33–57 43 receptor-stimulator with ipsilateral and contralateral microphones. The outcomes were evaluated at three and six months after the first fitting. Results: Sound direction identification is better with bilateral versus unilateral implant. Bilateral stimulation is significantly better than unilateral stimulation when noise is presented ipsilaterally. Conclusions: Overall the cochlear implant users perceive their own performance to be better with bilateral implant vs. unilateral. C055 The musical stages profile (MSP): Acquisition of musical behaviours post cochlear implantation (CI) D. Vickers, S. Edwards, G. Kirkim, L. Olgun, A. Incesulu, E. Yucel, S. Onder, I. Akin. UCL Ear Institute, London, UK; Dokuz Eylul University Hospital, Izmir, Turkey; SB Izmir Bozyaka Hospital, Turkey; Eskisehir Osman Gazi University Hospital, Turkey; Hacettepe University Hospital, Ankara, Turkey; SB Ankara Numune Hospital, Turkey; SB Ankara Diskapi Hospital, Turkey Aims: To validate MSP questionnaire looking at emergence of musical behaviours in children and to compare CI-children to agematched norms. Material and Methods: 74 normal-hearing participants (aged 6– 96 months) were used for MSP validation. 35 CI-children (14–64 months at CI) were also assessed. Results: Test re-test results from parents completing MSP on two occasions demonstrated high repeatability (r = 0.947, p< 0.01). Cronbach’s Alpha was greater than 0.7 (0.92) suggesting high internal reliability. An expert review explored content validity and structure and reduced questionnaire to 23 items grouped according to melody, rhythm and emotional aspects. The percentage of CI children acheiving age-appropriate level by 6 months for melody, rhythm and emotional aspects was 71, 94 and 67% respectively and there was a developmental change over this 6-month period. Conclusions: MSP is a reliable, repeatable, developmentallysensitive measure. CI-Children demonstrated improvements on MSP post-CI, taking longer for melody and emotional aspects than for rhythm. C056 Phonetic accuracy and phonological processes in Australian children using cochlear implants S. Dettman, J. Bardsley, C. Holt, R. Dowell, K. Galvin. The University of Melbourne, Australia Aim: The phonetic accuracy of vowels, consonants and clusters and the prevalence of developmental and non-developmental phonological processes was examined in 48 Australian children (23 m, 25 f) aged 6 yrs 8 mo (range 3.0 to 11.8; SD 2.0 yrs). Material and Methods: The Diagnostic Evaluation of Articulation and Phonology (DEAP) results were entered into the Computer Aided Speech and Language Analysis (CASALA) program. The relationship between demographic/developmental variables and speech outcomes was examined. Results: Earlier age at CI and an Aural/Oral approach were associated with higher phonetic accuracy and fewer erroneous phonological processes. Gender and age at hearing-aid fitting were not associated with speech production outcomes. Patterns of vowel and consonant errors are discussed. Conclusions: The results of this study support the benefits of an Aural/Oral communication mode for facilitating speech accuracy in early childhood. Using CASALA analysis of the DEAP was an efficient and valid clinical and research tool. C057 Speech performance and sound localization abilities in Neurelec Digisonic SP Binaural cochlear implant users N. Verhaert, J.P. Bebear, D.S. Lazard, D. Gnansia, Ph. Romanet, B. Meyer, E. Truy.

The purpose of this study was to evaluate whether this binaural cochlear implant could offer similar benefits as bilateral implantation. Material and Methods: Fourteen adults implanted with a Digisonic SP Binaural were evaluated. Testing included speech perception (in quiet and in noise) and sound localization both in binaural and unilateral condition, but also head-shadow, squelch and summation effects. Results: Speech scores in quiet and noise, and localization accuracy were significantly better in binaural than in unilateral condition. Squelch effect was on average as good as head-shadow. No explantation, hard or soft failure was observed. Conclusions: This device provides similar benefits in speech recognition and sound localization as bilateral cochlear implants. Squelch showed noticeable values in this study, synchronous discharge between left and right sides provided by the implant can explain this effect. C058 Improved speech reception and sound quality with DUET 2 in electric acoustic stimulation (EAS) A. Kleine Punte, E. Cochet, M. Eisendle, P. Van de Heyning. Univ.Dept. Otorhinolaryngology and Head and Neck Surgery, University Hospital Antwerp; University of Antwerp, Belgium; Med-El, Clinical Research Department, Innsbruck, Austria Aim: EAS is an efficient treatment for patients with partial deafness. The DUET 2 audioprocessor for EAS was evaluated. Material and Methods: 8 EAS patients were upgraded from the DUET to the DUET 2 audioprocessor. Speech perception in quiet and noise and sound quality for speech and music were assessed with both devices up to 6 months after switch-over. Results: Adaptive speech testing showed a significant improvement of 4.3 dB (p =0.035) in quiet and 6.3 dB (p =0.001) in noise with the DUET 2 compared to the DUET after 6 months. Fixed level speech perception with the DUET 2 significantly improved with 23.2% (p =0.028) in quiet and 17.1% (p =0.031) in noise. Also sound quality of the DUET 2 rated significantly better than the DUET. Conclusions: With the DUET 2 speech perception in quiet and noise improved significantly. Subjectively the DUET 2 was also clearly preferred by the users over de DUET.
