“…The Sophono Alpha system is a bone-conductive transcutaneous implant that transmits the vibrations of the external processor thought an intact skin by means of a magnetic coupling. It was first described by Siegert [2011], and since then other papers have been published concerning the use of this device in different pathological conditions [Denoyelle et al, 2013;Escorihuela-García et al, 2014;Hol et al, 2013;Leterme et al, 2015;Magliulo et al, 2015;Siegert and Kanderske, 2013;Sylvester et al, 2013].…”

Single-sided deafness (SSD) represents one of the most difficult audiological conditions to rehabilitate. The aim of this prospective study was to evaluate the audiological benefits and quality of life of patients affected by SSD who had previously been users of the Alpha 1® when upgrading them to the Sophono Alpha 2® external processor (Boulder, Colo., USA). Nine patients were included in the study. They underwent physical examination, free-field speech audiometry at 40 and 60 dB, a hearing-in-noise test (Hirsch's test and the squelch test), the Glasgow Benefit Inventory (GBI) questionnaire, and a specific questionnaire on patient satisfaction with Alpha 1. Afterwards, the Alpha 2 external processor was delivered to all patients, and the above-mentioned protocol was repeated after 1 month with the Alpha 2. A statistically significant improvement was found in the speech discrimination score at 40 dB and in the squelch test when using the Alpha 2 external processor compared to the Alpha 1. Alpha 2 had a good clinical tolerance and gave similar results in the specific questionnaire and the GBI to Alpha 1. In conclusion, the new Alpha 2 external processor represents a safe and effective device for the rehabilitation of SSD, and there is an audiological benefit to upgrading to the Alpha 2 external processor for patients who had previously been users of the Alpha 1. The improvement in quality of life is similar to that with other bone-anchored hearing devices.

“…Alpha 1 ® (Sophono, Boulder, Colo., USA) is a transcutaneous bone conduction device with an external active part coupled to implanted magnets under an intact cranial skin. Its cosmetic advantages and lower risk of trauma in children are evident, and the first clinical trials in conductive hearing losses have shown an improvement in comfort and safety compared to percutaneous bone conduction hearing aids [Siegert, 2011;Denoyelle et al, 2013]. In this study, we evaluated this transcutaneous bone conduction device in SSD, in comparison to a noninvasive rehabilitation method (CROS hearing aid) in terms of hearing performances, user satisfaction, and quality of life.…”

The aim of this study was to compare a contralateral routing of signal (CROS) hearing aid to a transcutaneous bone-anchored device in the same conditions. This prospective crossover study included 18 adult patients with a single-sided deafness (SSD). After a trial period of 60 days with CROS and 7 days with a transcutaneous bone-anchored device (Alpha 1®, Sophono, Boulder, Colo., USA) on a headband, 13 (72%) patients opted for Alpha 1, 2 patients for CROS, and 3 rejected both rehabilitation methods. Clinical tolerance, satisfaction, hearing performances (pure-tone audiometry, speech test in quiet and in noise, stereo audiometry, sound localization, and Hearing in Noise Test), and quality of life (Glasgow Benefit Inventory, Abbreviated Profile of Hearing Aid Benefit and Glasgow Hearing Aid Benefit questionnaires) were measured at 3 and 12 months after the implantation. Both devices improved equally the hearing in noise and the quality of life. Transcutaneous devices represent an effective option in SSD.

“…The external sound processor houses a bone oscillator and uses a metal disc and spacer shim to magnetically couple to the internal component and deliver auditory stimulation through the closed skin. This has been used in over a series of 100 patients (adults and children above the age of 5 with bone conducting thresholds better than or equal to 45 dB HL) [54]. Its main advantage is that it has no skin penetrating abutment and therefore eliminates the risk of abutment skin reactions.…”
