Experimental investigation of promontory motion and intracranial pressure following bone conduction: Stimulation site and coupling type dependence [PDF]
Investigation of bone conduction sound propagation by osseous and non-osseous pathways and their interactions based upon the stimulation site and coupling method of the actuator from a bone conduction hearing aid (BCHA).Experiments were conducted on five Thiel embalmed whole head cadaver specimens.

Safe electrical stimulation of the cochlear nerve at the promontory during functional magnetic resonance imaging [PDF]
The purpose of this study was to evaluate possibilities and technical risks for combining intended electrical stimulation of the cochlear nerve and functional magnetic resonance imaging (fMRI). Theoretical considerations and experiments indicate that fMRI can be performed safely during electrical stimulation.

Evaluation of Electric Promontory Stimulation Test for Cerebellopontine Angle Tumors.
Transtympanic electric promontory stimulation (EPS) was first performed by House & Brackmann for the purpose of differentiating between sensory and neural type deafness. There are few reports dealing with EPS in neural deafness. This paper focuses on the accuracy of EPS, with the use of a promontory stimulator (Nucleus Co.), in patients with neural ...

EFFECTS OF ELECTRICAL PROMONTORY STIMULATION AND BAND-NOISE MASKER IN THE SUPPRESSION OF TINNITUS
The effects of electrical promontory stimulation (EPS) and band-noise masker (BNM) were examined in 102 patients suffering from tinnitus. The effects of EPS were as follows: complete suppression in 8 patients (8%), partial suppression in 53 patients (52%), no effect in 40 patients (39%), and exacerbation in 1 patient (1%).

A COMPARISON OF TIME RESOLUTION AMONG AUDITORY, TACTILE AND PROMONTORY ELECTRICAL STIMULATION
Our previous reports showed that second formant information, using a speech coding method, could be transmitted through an electrode on the promontory. However, second formant information can also be transmitted by tactile stimulation. Therefore, to find out whether electrical stimulation of the auditory nerve would be superior to tactile stimulation ...

High-Resolution EEG Amplifiers Are Feasible for Electrocochleography Without Time Restriction [PDF]
Objectives: The gold standard for electrocochleography (ECochG) is using dedicated recording devices for auditory evoked potentials. However, these have a very limited time window for recording.

We performed Electrical Promontory Stimulation (EPS) for the suppression of tinnitus in 52 patients and measured Compound Action Potentials (CAP) using electrocochleography before and after EPS. We examined the relation between residual inhibition and CAP. The purpose of this study was to investigate the origin and mechanism of suppression of tinnitus.

Stimulation sites closer to the cochlea result in higher output for bone conduction devices (BCD), increasing maximum output and reducing energy consumption. In our study, alternative coupling sites closer to the ear canal (EC), in cortical and spongious bone, were investigated and the influence on ipsi- and contralateral bone conduction output was ...
