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.

The role of the promontory stimulation test in cochlear implantation
Cochlear Implants International, 2002 To date, 290 adults have been implanted in the cochlear implant programme in Sydney (Australia), where the promontory stimulation test (PST) is routinely used to assess implant candidacy. There has been much controversy over the exact role and value of this test.

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.

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.

A Study of Electrical Promontory Stimulation in Tinnitus Patients
Auris Nasus Larynx, 1994 Electrical promontory stimulation relieved tinnitus in 74 (57.4%) of 129 ears (112 patients). There was no significant difference in etiology of tinnitus, age, average audiogram, or tinnitus frequency between patients who responded to electrical stimulation and those who did not.

Perfusion SPECT in cochlear implantation and promontory stimulation
Nuclear Medicine Communications, 2004 Recent studies of profoundly deaf patients with cochlear implants have demonstrated that these patients are able to process sound in the auditory cortex in a similar way to normal subjects. However, there are large variations in outcome. Various clinical criteria are used for subject selection and the decision as to which ear is to be implanted ...

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 ...

Value of the Promontory Stimulation Test in Predicting Speech Perception After Cochlear Implantation
The Laryngoscope, 2007 AbstractBackground and Objectives: To determine the role of the promontory stimulation test (PST) in cochlear implantation (CI), we evaluated the correlations between PST parameters and the results of speech perception tests after CI.Subjects and Method: With use of a retrospective review of the medical records of 58 patients, the GAP50, GAP100, TDL50,

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

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 ...
