Electrically evoked auditory brainstem responses in cochlear implant patients.
Electrically evoked auditory brainstem responses (EABR) were recorded in completely deaf patients implanted with Ineraid multichannel cochlear implants. Clear and reproducible EABR were obtained from all patients. Parametric differences with auditory brainstem responses (ABR) were demonstrated and can be explained by the different natures of both types of stimulations (electric versus acoustic)...
متن کاملAUDITORY BRAINSTEM RESPONSES (ABR) IN HYPERBILIRUBINEMIC NEWBORNS
To evaluate the changes of ABR values in hyperbilirubinemic newborns, 85 cases with severe jaundice (total bilirubin levels over 16 mg/dL and direct bilirubin less than 2 mg/dL) were selected from those admitted to Children's Medical Center by simple sampling method. These infants had no other problem except jaundice. ABR was taken before treatment in all cases and in some (10 cases) after...
متن کاملBrainstem auditory evoked responses in brainstem infarction.
Brainstem auditory evoked responses (BAERs) were recorded in 40 patients with clinically definite brainstem infarction, and results were compared to localizations from physical signs and CT scans. The BAER was abnormal in 92% of patients with evidence on physical examination of dysfunction of lateral structures in the pons or midbrain. Normal BAERs were seen with medially-situated or medullary ...
متن کاملRecording Electrically-evoked Auditory Brainstem Responses (EABR) in Human Cochlear Implant Subjects
– Auditory Brainstem Responses (ABR) and Electrically-evoked Auditory Brainstem Responses (EABR) are two closely related exogenous auditory evoked potentials (AEP) elicited from EEG measurements [1]. ABR is used as a hearing screening tool for newborns [2] and general hearing loss [3], while EABR is used in cochlear implant (CI) intraoperative monitoring [4] and speech processor tuning [5]. He...
متن کاملThe relationship between electrical auditory brainstem responses and perceptual thresholds in Digisonic® SP cochlear implant users.
Determining the electrical stimulation levels is often a difficult and time-consuming task because they are normally determined behaviorally - a particular challenge when dealing with pediatric patients. The evoked stapedius reflex threshold and the evoked compound action potential have already been shown to provide reasonable estimates of the C- and T-levels, although these estimates tend to o...
