Promontory stimulation following labyrinthectomy: Implications for cochlear implantation
The Laryngoscope, 1990 AbstractTranstympanic electric promontory stimulation is a psy‐choacoustic test used to assess residual acoustic neurons in profound sensorineural hearing loss. The test was performed in six patients who had previously undergone trans‐mastoid (N = 5) or transcanal‐oval window (N = 1) labyrinthectomy as a means of determining the feasibility of future ...

The role of the promontory stimulation test in cochlear implantation
Cochlear Implants International, 2002To 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.

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 ...

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 ...

Value of the Promontory Stimulation Test in Predicting Speech Perception After Cochlear Implantation
The Laryngoscope, 2007AbstractBackground 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,

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 ...

Promontory stimulation following labyrinthectomy
The Journal of Laryngology & Otology, 1991 AbstractPromontory stimulation testing was carried out on a series of ten patients who had undergone osseous labyrinthectomy. The thresholds, discomfort levels and dynamic ranges were found to be comparable with a series of ten patients who have subsequently been successfully implanted with the Nucleus 22 channel cochlear implant.

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

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 ...

Hearing Research, 2019
As an alternative pathway to air conduction, bone conduction is a multipathway process that transmits sound energy to the inner ear through the skull in general. Based on this mechanism, bone conduction devices (BCDs) have been used widely in the rehabilitation of hearing loss. Although great efforts have been devoted to improving BCDs, drawbacks still
