Abstract (sommario):

Thirty-eight patients who underwent endolymphatic shunt surgery with intraoperative electrocochleography were questioned regarding control of symptoms. The average follow-up period was 2 years (range, 7 to 40 months). Sixteen (42%) patients showed improvement in the intraoperative electrocochleography potential, 12 (32%) showed worsening, and 10 (26%) showed no change. Complete or substantial control of dizziness was achieved in 36 (95%) patients, and insignificant control in only 2 (5%) patients. Hearing Improvement was noted in 4 (11%) patients, and hearing loss in 13 (34%). No correlation was found between intraoperative electrocochleography improvement and dizziness control. However, three of the four patients who had hearing improvement also had the greatest improvement in intraoperative electrocochleography recording. Intraoperative electrocochleography may help the surgeon more accurately identify the true endolymphatic sac and duct.

Abstract (sommario):

AbstractThe near field monitoring of an auditory evoked response from the cochlear (electrocochleography) is a tried and trusted clinical tool. Conventional techniques for performing electrocochleography are cumbersome to use and frequently uncomfortable for the patient. We present a simple, modified technique which provides more flexibility with regard to where and when electrocochleography may be performed and also improves patient comfort during the test.

Abstract (sommario):

AbstractThis case reports electrophysiological evidence for cochlear function in a child with radiological evidence of bilateral auditory nerve agenesis or severe hypoplasia. The diagnosis of auditory nerve agenesis was supported by a bilateral atresia of internal auditory canals on computed tomography (CT) scan and magnetic resonance imaging (MRI) absent auditory brainstem responses and absent behavioural responses to sound. Despite the apparent absence of an auditory nerve or spiral ganglion, electrocochleography revealed surviving cochlear function at 70–80 db HL and an abnormal electrocochleographic waveform. This case demonstrates that cochlear function may develop without afferent, or efferent innervation. It also emphasizes that cochlear function may occur in the presence of profound deafness.

Abstract (sommario):

In search of biomarkers for cochlear neural degeneration (CND) in electrocochleography from humans with normal thresholds, we high-pass and low-pass filtered the responses to separate contributions of auditory-nerve action potentials (N1) from hair-cell summating potentials (SP). The new N1 measure is better correlated with performance on difficult word-recognition tasks used as a proxy for CND. Furthermore, the paradoxical correlation between larger SPs and worse word scores, observed with classic electrocochleographic analysis, disappears with the new metric. Classic SP is simultaneous with and opposite in phase to an early neural contribution, and filtering separates the sources to eliminate this interference.

Abstract (sommario):

OBJECTIVE: We investigated and compared the usefulness of the electrocochleography and distortion product otoacoustic emission tests for detecting the earliest noise-induced damage by analyzing the sensitivity and specificity of the 2 tests. STUDY DESIGN: A prospective study. METHODS: After listening to music at 90.3 ± 4.2 dB in the same night-club for 2 hours continuously, 23 healthy normal ears experienced a temporary threshold shift exceeding 5 dB. Pure-tone audiometry, the distortion product otoacoustic emission test, and electrocochleography were performed before, immediately after, and 24 hours after the exposure. RESULTS: Before exposure, the measured distortion product/noise floor was 9.8 ± 10.4, 23.5 ± 6.4, 18.7 ± 6.4, and 19.1 ± 5.6 dB sound pressure level (SPL) at frequencies of 1, 2, 3, and 4 kHz, respectively. Immediately after exposure, it decreased significantly at 2, 3, and 4 kHz to 16.6 ± 7.6, 12.5 ± 6.8, and 14.8 ± 7.7 dB SPL, respectively. Marked increases in the amplitude of the summating potential and summating potential/action potential ratio were recorded from 0.15 ± 0.06 to 0.32 ± 0.11 and 0.23 ± 0.06 to 0.44 ± 0.08, respectively. The respective sensitivity and specificity of electrocochleography were 76.7% to 88.5% and 91.0% to 100%. Those of the distortion product otoacoustic emission test were 54.8% to 62.2% and 75.5% to 87.0%, respectively. CONCLUSION: Electrocochleography appears to provide more sensitive and specific information than the distortion product otoacoustic emission test for detecting a noise-induced temporary threshold shift.

Abstract (sommario):

The stapedial reflex (SR) can be obtained by the impedance method only when the middle ear is intact. In order to examine the function of the stapedius muscle in diseased ears, the recording of the stapedial electromyogram by an electrocochleographic (ECoG) method was considered. The SR was recorded simultaneously by the impedance method in ten normal subjects for comparison. The outputs of ECoC were averaged by a signal processor up to 200 times under a longer sweep time, and a large biphasic wave with a latency of about 11 ms was obtained on the ECoC records. The amplitude increase of the biphasic wave caused by raising the intensity of the acoustic stimulation paralleled that of the SR. This means that the biphasic wave obtained by ECoC with a latency of about 11 ms originated from the stapedius muscle.

Abstract (sommario):

Interruption of cochlear blood flow has been implicated as one of the causes of the sensorineural hearing loss that may occur during acoustic neuroma surgery. With the guinea pig as an animal model for cerebellopontine angle surgery, laser-Doppler measurements were used to estimate the cochlear blood flow changes caused by compression of the eighth nerve complex. With compression, the laser-Doppler measurements decreased abruptly; somewhat later, the electrocochleographic potentials declined. When compression was released, laser-Doppler measurements usually returned immediately, followed later by return of the electrical potentials. Some of these potentials, including the compound action potential of the auditory nerve, often became transiently larger than their precompression values. Interposing bone between the laser-Doppler probe and the otic capsule, so that the total bone thickness approximated the thickness of the human otic capsule, decreased the laser-Doppler measurement, but changes caused by compression were still apparent. Thus, although the human otic capsule is much thicker than the guinea pig capsule, it may still be possible to make laser-Doppler estimates of human cochlear blood flow. Laser-Doppler monitoring during acoustic neuroma surgery may be beneficial, because it could give earlier warning of ischemia than is currently available from electrocochleographic monitoring, thereby enabling earlier corrective action. Electrocochleography complements laser-Doppler measurements by indicating the physiologic state of the cochlea.

Abstract (sommario):

AbstractThe newly developed use of magnetic resonance imaging of the human inner ear, on a 3 Tesla scanner with intratympanically administered gadolinium, can now reliably distinguish perilymph from endolymph and visually confirm the presence or absence of endolymphatic hydrops. Transtympanic tone burst electrocochleography is an established, and under-utilised evoked response electrophysiological test for hydrops, but it relies on a symptom score to indicate the likelihood of hydrops being present. The current diagnostic criteria for Ménière's disease make no allowance for any in vivo test, making diagnostic errors likely. In this small pilot study of three patients undergoing tone burst electrocochleography, subsequent magnetic resonance imaging confirmed or excluded the hydrops that the electrocochleography predicted. Magnetic resonance imaging of the inner ear is a safe technique that can be performed in conjunction with imaging of the VIIIth cranial nerves. As this report comprised only three patients in a pilot study, rigorous clinical studies are required to define the possible role of magnetic resonance imaging in the diagnosis of Ménière's disease.

Abstract (sommario):

Aim: To obtain direct evidence for the cochlear travelling wave in humans by performing electrocochleography from within the cochlea in subjects implanted with an auditory prosthesis. Background: Sound induces a travelling wave that propagates along the basilar membrane, exhibiting cochleotopic tuning with a frequency-dependent phase delay. To date, evoked potentials and psychophysical experiments have supported the presence of the travelling wave in humans, but direct measurements have not been made. Methods: Electrical potentials in response to rarefaction and condensation acoustic tone bursts were recorded from multiple sites along the human cochlea, directly from a cochlear implant electrode during, and immediately after, its insertion. These recordings were made from individuals with residual hearing. Results: Electrocochleography was recorded from 11 intracochlear electrodes in 7 ears from 6 subjects, with detectable responses on all electrodes in 5 ears. Cochleotopic tuning and frequency-dependent phase delay of the cochlear microphonic were demonstrated. The response latencies were slightly shorter than those anticipated which we attribute to the subjects' hearing loss. Conclusions: Direct evidence for the travelling wave was observed. Electrocochleography from cochlear implant electrodes provides site-specific information on hair cell and neural function of the cochlea with potential diagnostic value.

Abstract (sommario):

AbstractMultiple sclerosis is known to affect the myelin of the auditory pathway resulting in acute hearing loss. Two cases of sudden deafness due to multiple sclerosis have been evaluated by conventional audiometry, brainstem auditory evoked response audiometry and transtympanic electrocochleography. The abnormalities of the compound action potential in both patients (enhanced latency, abnormal adaptation using fast stimulus rate) and the normal receptor potentials (cochlear microphonic, summating potential), as well as the absence of brainstem responses suggest a disturbance of synchronization at the level of the first auditory neurone. The electrocochleography provides valuable information for the topodiagnosis of this and other neural hearing losses, especially in the absence of reliable brainstem responses.
