The mean pretreatment 4-frequency pure tone average was 81 dB. The mean aided pure tone averages with the BCD and CCD were 27 and 32 dB (P = .002), and the mean functional gains were 54 and 49 dB (P =...
Pure tone audiometric outcomes with the BCD show a small advantage over the CCD, with the difference driven mainly by high-frequency responses. Speech outcomes were equivalent apart from the +5-db SNR...

Patients underwent simultaneous or sequential bilateral surgery for ABCI....
The speech intelligibility in noise was assessed with the Ita Matrix test in summation, squelch and head shadow settings. First, the tests were performed with one device activated in the ear with lowe...
When bilateral devices were activated, an improvement of signal-to-noise ratio was observed in all settings. The difference between bilateral and unilateral stimulation is 4.66 dB ( p = 0.016) in the ...
In symmetric mixed bilateral hearing loss, rehabilitation with an ABCI fitted bilaterally shows audiologic advantages in speech perception in noise, not only thanks to the summation effect and by redu...
Under bone conduction (BC) stimulation, the otic capsule, and surrounding temporal bone, undergoes a complex 3-dimentional (3D) motion that depends on the frequency, location and coupling of the stimu...
Experiments were conducted in 3 fresh frozen cadaver heads, individually on each temporal bone, resulting in a total of 6 samples. The skull bone was stimulated, via the actuator of a BC hearing aid (...
While there were limited differences in the magnitude of the motion across the skull base, there were major differences in the deformation of different sections of the skull. Specifically, the bone ne...
The area around the otic capsule appears rigid up to significantly higher frequencies than the rest of the skull surface, resulting in primarily inertial loading of the cochlear fluid. Further work sh...

Nine patients (mean age 37 ± 16 years, range 14-57 years) were examined pre- and 12 months postoperatively for word recognition scores (WRS) at 65 dB SPL, sound-field (SF) thresholds, bone conduction ...
Due to avoidance of one surgical step, the surgical technique was simplified. Mean WRS in SF was 11.1 ± 22.2% (range 0-55%) pre- and 77.2 ± 19.9% (range 30-95%) postoperatively; mean SF threshold (pur...
Implant fixation by means of self-drilling screws was safe and effective in all nine patients. There was significant audiological benefit 12 months after implantation....
