Cortical responses to promontorial stimulation in postlingual deafness
Hearing Research, 2005Electrical stimulation with a transtympanic electrode on the promontory of the middle ear allows the tasks of gap detection and temporal difference limen (TDL) to be carried out by both normally hearing and deaf subjects. Previous neuroimaging of normally hearing subjects revealed a region in the right posterior temporal lobe that is crucial to ...

Promontory stimulation following labyrinthectomy
The Journal of Laryngology & Otology, 1991AbstractPromontory 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 Electrical Stimulation in Labyrinthectomized Ears
Archives of Otolaryngology - Head and Neck Surgery, 1990Bilateral 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 ...

Perfusion SPECT in cochlear implantation and promontory stimulation
Nuclear Medicine Communications, 2004Recent 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 postoperative acoustic tumor patients
The Laryngoscope, 1992AbstractComplete 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: Implications for cochlear implantation
The Laryngoscope, 1990AbstractTranstympanic 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 ...

Round Window versus Promontory Stimulation: Assessment for Cochlear Implant Candidacy
Annals of Otology, Rhinology & Laryngology, 1991Electrical 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 ...

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.

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
