Bone conduction stimulation efficiency at coupling locations closer to the cochlea [PDF]

Scientific Reports
Bone conduction implants enable patients to hear via vibrations transmitted to the skull. The main constraint of current bone conduction implants is their maximum output force level.

In Vivo Measurement of Ear Ossicle and Bony Wall Vibration by Sound Stimulation of Cartilage Conduction [PDF]

Audiology Research, 2023
The cartilage-conduction pathway was recently proposed as a third auditory pathway; however, middle-ear vibrations have not yet been investigated in vivo.

Evaluating temporal bone column density for optimized bone conduction implant placement [PDF]

Frontiers in Surgery, 2023
IntroductionAn optimal placement of bone conduction implants can provide more efficient mechanical transmission to the cochlea if placed in regions with greater bone column density.

Electrical promontory stimulation test using a portable peripheral nerve stimulator with an ear canal electrode

Auris Nasus Larynx, 2023
An intact cochlear nerve is necessary for successful cochlear implantation (CI). Although the promontory stimulation test (PST) using a promontory stimulator (PS) and a transtympanic needle electrode is invasive, it is still commonly used to verify cochlear nerve function.

Objective preclinical measures for bone conduction implants [PDF]

Frontiers in Neuroscience
The study evaluates the accuracy of predicting intracochlear pressure during bone conduction stimulation using promontory velocity and ear canal pressure, as less invasive alternatives to intracochlear pressure.

Intracranial Pressure and Promontory Vibration With Soft Tissue Stimulation in Cadaveric Human Whole Heads [PDF]

Otology & Neurotology, 2016
Intracranial pressure and skull vibrations are correlated and depend on the stimulation position and frequency.A hearing sensation can be elicited by vibratory stimulation on the skin covered skull, or by stimulation on soft tissue such as the neck. It is not fully understood whether different stimulation sites induce the skull vibrations responsible ...

Electrical stimulation of the cochlea for treatment of chronic disabling tinnitus: an open-label trial towards the development of an implantable device [PDF]

Journal of Translational Medicine, 2022
Background Chronic tinnitus affects millions of people globally and constitutes the most commonly compensated disability among military service members in the United States.

Electrical promontory stimulation in patients with intact cochlear nerve and anacusis following acoustic neuroma surgery [PDF]

The Laryngoscope, 1992
AbstractAnacusis following hearing preservation surgery for acoustic neuroma removal in which the cochlear nerve was preserved has been explained on the basis of neural or vascular compromise. In the absence of pathologic evidence for either theory, a physiologic model was chosen.

Experimental investigation of promontory motion and intracranial pressure following bone conduction: Stimulation site and coupling type dependence [PDF]

Hearing Research, 2019
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.

Suppression of Tinnitus by Electrical Promontory Stimulation.

AUDIOLOGY JAPAN, 1992
我々は岬角電気刺激により耳鳴を抑制することを試みた。 対象は59例, 62耳であり, 男性34名, 女性25名で, 聴力レベルは, 軽度感音性難聴より聾型までを含む。 岬角電気刺激装置としてはコクレア社製promontory stimulatorを用い, 刺激波として2相性のパルスバーストを用いた。 耳鳴の抑制率は, 原因不明の感音性難聴76.9%, 突発性難聴85.7%, 耳毒性薬物, 騒音などの原因による内耳性難聴80.0%, メニエール病83.3%, 中耳炎などの原因による内耳炎71.4%, 聴神経腫瘍8.3%, 平均66.1%であった。 以上より, 内耳性の耳鳴には抑制率が高く, 後迷路性のものについては低い結果となり, 耳鳴の病巣部位の推定に岬角電気刺激検査が有用であると思われた。
