A Comparison of Acoustic and Electric Reflex Thresholds (ESRT)
Scottsdale/Phoenix, Ariz.,
Rochester, Minn.
The purpose of this study is to analyze immittance patterns, both acoustically and electrically, for patients with either cochlear implantation or auditory brainstem implantation.

A Pivotal, Prospective, Multi-centre, Randomize Control, Blinded Study Evaluating the
Efficacy of a Dexamethasone Eluting Slim Modiolar Electrode (CI632D) in the Reduction
of Fibrosis as Compared to a Standard Slim Modiolar Electrode (CI632) in a Newly
Implanted Adult Population with Bilateral, Post-Linguistic, Moderate to Profound
Sensorineural Hearing Loss (CI-DEX)
Rochester, Minn.
The purpose of this study is show the effectiveness of a dexamethasone eluting electrode in an adult population with post-lingual, bilateral, moderate to profound sensorineural hearing loss in the reduction of fibrosis (as measured by impedance) when compared to a conventional, non-dexamethasone eluting electrode and in the improvement of speech recognition from preoperative baseline.
-
Cochlear implant electrode impedances as a function of level and charge.
Rochester, Minn.
To determine if changes in cochlear implant electrode impedances change as a function current level and charge that is used to measure electrode impedances.
-
Effect of Electrode Impedance Fluctuations on Cochlear Implants
Rochester, Minn.
The purpose of this study is to determine the effect of fluctuating electrode impedances on speech perception in cochlear implants.
-
Intra- and Post-operative Measures of Auditory Function
Rochester, Minn.
The purpose of this study is to determine if electrocochleography (ECochG) measurements performed during cochlear implant surgery can be used to monitor cochlear structures and minimize electrode insertion trauma.
-
Remote Objective Monitoring: Neural Response and Cochlear Implant Electrode Impedance Measurements
Rochester, Minn.
Hypothesis: Cochlear implant and Auditory Brainstem Implant outcomes continue to improve secondary to improved device design, surgical approach, and advanced programming.
-
Wideband Tympanometry Measurements in Individuals with Unilateral Otosclerosis, and Unilateral and Bilateral Cochlear Implant Recipients
Rochester, Minn.
The purpose of this study is to measure the changes in the middle ear mechanics or the transfer function in cochlear implant recipients and compare those changes with the middle ear transfer function measured in individuals with unilateral otosclerosis.
