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.

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.

Promontory Stimulation Following Labyrinthectomy
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 ...

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 ...

Round Window versus Promontory Stimulation: Assessment for Cochlear Implant Candidacy
Annals of Otology, Rhinology & Laryngology, 1991 Electrical stimulation of the cochlea is a part of the preliminary evaluation protocol for cochlear implant candidacy at many centers. Typically, a transtympanic needle electrode is placed on the promontory of the ear under consideration and electrical current is presented to measure auditory percepts and psychophysical-electrophysiologic measures ...

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 ...

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.

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 ...

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 ...

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
