Sensorineural Hearing Loss

Effects of Hearing Loss

Professional Journal Article # 2 : " Long term patient satisfaction with different middle ear hearing implants in Sensorineural Hearing loss."

Implantable hearing devices are a valuable option for patients with moderate-to-serve sensorineural hearing loss who cannot benefit from conventional hearing aids. Only 20% to 42% were satisfied with their implants compared with their contralateral conventional hearing aids. Conventional hearing aids are no longer the exclusive solution to patients with sensorineural hearing loss.

Professional Journal Article #1: Auditory brainstem and hearing stimulation

Patients suffering from conductive or mixed hearing loss and Single-Sided Deafness may benefit from implantable hearing devices relying on bone conducted auditory stimulation.  This study focuses on the feasibility aspect of an electrophysiological determination of the hearing  with bone-anchored hearing aid stimulation. Auditory evoked potentials were measured by auditory stimulation paradigm used in clinical routine. The amplitudes and latencies, of the resulting auditory brainstem responses  and the cortically evoked responses were correlated with the respective responses without the use of the Baha Intenso. The recording of ABR and CAEP by delivering the stimuli to the Baha results in response waveforms which are comparable to those evoked by earphone stimulation and appears appropriate to be measured using the Baha Intenso as stimulator.  At all measurements, the ABR and CAEP seem to be consistent with the normal hearing of the patient.
