“…The receiver is similar to the monaural Digisonic SP device: the coil, magnet, and electronics are boxed in a single ceramic structure. The receiver fixation is assured by two titanium screws, without drilling a bony well [Guevara et al, 2010]. Each electrode array comprises twelve active electrodes along an 18-mm active length, with an associated extra-cochlear ground electrode.…”

In this prospective study the outcome of the Digisonic® SP Binaural cochlear implant (CI), a device enabling electric stimulation of both cochleae by a single receiver, was evaluated in 14 postlingually deafened adults after 12 months of use. Speech perception was tested using French disyllabic words in quiet and in speech-shaped noise at +10 dB signal-to-noise ratio. Horizontal sound localization in quiet was tested using pink noise coming from 5 loudspeakers, from –90 to +90° along the azimuth. Speech scores in quiet were 76% (±19.5 SD) in the bilateral condition, 62% (±24 SD) for the better ear alone and 43.5% (±27 SD) for the poorer ear alone. Speech scores in noise were 60% (±27.5 SD), 46% (±28 SD) and 28% (±25 SD), respectively, in the same conditions. Statistical analysis showed a significant advantage of the bilateral use in quiet and in noise (p < 0.05 compared to the better ear). Significant spatial perception benefits such as summation effect (p < 0.05), head shadow effect (p < 0.0001) and squelch effect (p < 0.0005) were noted. Sound localization accuracy improved significantly when using the device in the bilateral condition with an average root mean square of 35°. Compared with published outcomes of usual bilateral cochlear implantation, this device could be a valuable alternative to two CIs. Prospective controlled trials, comparing the Digisonic SP Binaural CI with a standard bilateral cochlear implantation are mandatory to evaluate their respective advantages and cost-effectiveness.

“…The Digisonic SP (MXM -Neurelec, Vallauris, France) implant was introduced in 2004 and has a similar basic layout to other currently available commercial devices, with a ceramic/titanium internal receiver package and an external ear-level speech processor [13]. Highly positive outcomes with this device have been reported in unilaterally implanted adults [14,15], but outcomes in children and, in particular, with bilateral devices have not yet been reported.…”

“…In the literature, authors have reported experiences similar to ours with revision surgery using the subperiosteal pocket technique (6,8). In this technique, drilling is unnecessary to create a bone bed for the IRS and electrodes.…”

Multicenter Evaluation of the Digisonic SP Cochlear Implant Fixation System with Titanium Screws in 156 Patients

Abstract: The fixation system with screws embedded in the Digisonic SP involves a fast and simple surgical technique that seems to efficiently prevent implant migration.
