Electrocochleographic Analysis of the Suppression of Tinnitus by Electrical Promontory Stimulation
International Journal of Audiology, 1997 To investigate the origin, and evaluate the mechanism by which tinnitus is suppressed we performed electrical promontory stimulation (EPS) in 56 patients with tinnitus, and measured the compound action potential (CAP) using electrocochleography before and after EPS.

Promontory Electrical Stimulation in Labyrinthectomized Ears
Archives of Otolaryngology - Head and Neck Surgery, 1990 Bilateral deafness can occur in patients with Menière's disease who have undergone a labyrinthectomy in one ear. To investigate the feasibility of a cochlear implant in the labyrinthectomized ear, promontory electrical testing by transtympanic needle was performed in six patients who had undergone a unilateral transmastoid labyrinthectomy 6 weeks to 5 ...

Promontory electrical stimulation to elicit vestibular evoked myogenic potentials (VEMPs)
Acta Oto-Laryngologica, 2015 Vestibular evoked myogenic potentials (VEMPs) provoked electrically at the promontory provide a feasible method to record vestibular responses in awake patients.Electrically evoked VEMP testing has been performed by galvanic stimulation at the mastoid so far.

Promontory electrical stimulation in postoperative acoustic tumor patients
The Laryngoscope, 1992 AbstractComplete deafness can follow acoustic tumor surgery and results from labyrinthine injury, auditory nerve trauma, and/or vascular compromise. A central auditory prosthesis is one potential rehabilitative strategy in such patients. Anatomical studies suggest that some spiral ganglion cells may survive after vascular occlusion, and we have ...

Utilization of Nerve Integrity Monitor for Promontory Stimulation Testing Prior to Cochlear Implant
Otology & Neurotology, 2018 Objective: To demonstrate the feasibility of a nerve integrity monitor as a tool for promontory stimulation testing in patients with profound sensorineural hearing loss considering cochlear implantation. Patients: Adult patients considered for cochlear implantation with no auditory ...

Neurophysiologie Clinique/Clinical Neurophysiology, 2002 Electrically evoked auditory potential (eEAP) techniques have been developed in order to assess electrical excitability of auditory nervous pathways in deaf patients before cochlear implantation. The aim of this study was to compare eEAPs recorded after a transtympanic promontory stimulation with those obtained after a round-window stimulation during a

Ear and Hearing, 1992 We compared within-subjects electrical thresholds and dynamic ranges obtained with direct round-window and transtympanic promontory stimulation carried out preoperatively in 12 patients who were candidates for a cochlear implant. Square waves with frequencies of 50, 100, 200, and 400 Hz were delivered in a 50% duty cycle to both sites in each patient ...

Audiology and Neurotology, 2020 <b><i>Introduction:</i></b> The aims of this study included: (a) to develop a method of direct acoustic bone conduction (BC) stimulation applied directly to the otic capsule, (b) to investigate the effect of different stimulation sites on the promontory displacement amplitude, and (c) to find the best stimulation site (among 2 ...

Auris Nasus Larynx, 2001 Almost 10-15% of the population suffer from chronic tinnitus. There are clinical indications that a 'pathological sound' may be induced by any level of the auditory pathways. Theraupeutical difficulties and many hypotheses about tinnitus and places from which they originate might indicate various methods of treatment.

British Journal of Audiology, 1986 The protocol for assessing patients for cochlear implantation at University College Hospital and the Royal National Institute for the Deaf, London, includes a session of electrophysiological tests and electrical stimulation of the cochlea. Electrocochleography is performed with the object of excluding non-organic hearing loss and of clarifying the site
