Outline

Text

Introduction: The author presents a new technique for the rehabilitation of profoundly deaf adult patients by cochlear electrical stimulation. Usually, one ear is implanted. Bilateral cochlear implantation experiences have been reported by the literature recently. The Digisonic SP Binaural is a 24 channels cochlear implant with two electrodes array. The first array is introduced in the ipsi-lateral cochlea with 12 electrodes. The longer second electrodes array is running under the galea for the stimulation of the contro-lateral ear with 12 electrodes. Only One speech processor Digi SP does the signal processing. In addition, a contro-lateral microphone is connected on the auxiliary input of the processor to give bilateral perception.

Material/Methods: Results on 7 patients will be given on various measurements with the binaural system :

1.
Free field tonal audiometry: left ear (LE), right ear (RE), both ears (R&LE) Audiometry with monosyllabic word lists.
2.
Free field Speech audiometry in silence:
LE, RE, L&RE
at 60, 70 dB SPL
SRT measurement
3.
Free field speech audiometry noise:
LE, RE, L&RE
white noise at 60 dB SPL
Speech at 50,60, 70 dB SPL
SRT measurement
Head shadow effect
Squelch effect
4.
Stereo audiometry with white noise at 65 dB SPL
5 Loud speakers
Localisation of sound sources (reliability, bias)

Results: The author will present the surgical procedure.

Conclusion: The Digisonic SP Binaural is a safe, reliable and an efficient solution for the binaural rehabilitation.
