Examining Delayed Recall in Cochlear Implant Users Using the Montreal Cognitive Assessment, California Verbal Learning Test, Third Edition, and Item Specific Deficit Approach: Preliminary Results.

Recent studies using the Montreal Cognitive Assessment (MoCA) suggest delayed recall is challenging for cochlear implant (CI) users. To better understand the underlying processes associated with delayed recall in CI users, we administered the MoCA and the California Verbal Learning Test, Third Edition (CVLT-3), which provides a more comprehensive assessment of delayed recall ability. The MoCA and CVLT-3 were administered to 18 high-performing CI users.

Estimating Real-World Performance of Percutaneously Coupled Bone-Conduction Device Users With Severe-to-Profound Unilateral Hearing Loss.

Purpose The bone-conduction device attached to a percutaneous screw (BCD) is an important treatment option for individuals with severe-to-profound unilateral hearing loss (UHL). Clinicians may use subjective questionnaires and speech-in-noise measures to evaluate BCD use in this patient population; however, the translation of these metrics to real-world aided performance is unclear. The purpose of this study was twofold: first, to measure speech-in-noise performance in BCD users with severe-to-profound UHL in a simulated real-world environment, relative to individuals with normal hearing bilaterally; second, to determine if BCD users' subjective reports of aided performance relate to simulated real-world performance.

Assessing Cognitive Abilities in High-Performing Cochlear Implant Users.

Despite being considered one of the most successful neural prostheses, cochlear implants (CIs) provide recipients with a wide range of speech perception performance. While some CI users can understand speech in the absence of visual cues, other recipients exhibit more limited speech perception. Cognitive skills have been documented as a contributor to complex auditory processing, such as language understanding; however, there are no normative data for existing standardized clinical tests assessing cognitive abilities in CI users.

Clinical Evaluation of the Patient with Otosclerosis.

Otosclerosis is a disorder presenting most commonly with unilateral conductive hearing loss. It can present as a mixed hearing loss also. Evaluation for otosclerosis relies on a specific history and physical examination, including tuning fork assessment and audiometric testing.

Multicenter US Clinical Trial With an Electric-Acoustic Stimulation (EAS) System in Adults: Final Outcomes.

Objective: To demonstrate the safety and effectiveness of the MED-EL Electric-Acoustic Stimulation (EAS) System, for adults with residual low-frequency hearing and severe-to-profound hearing loss in the mid to high frequencies.

Study Design: Prospective, repeated measures.

Setting: Multicenter, hospital.

Outcomes review of modern hearing preservation technique in cochlear implant.

Introduction: Preservation of residual hearing in cochlear implantation is a main concern for patients and otologists. New electrode arrays as well as development of minimally invasive technique have allowed the expansion of indication criteria for cochlear implantation. The loss of residual low-frequency hearing is thought to be the result of many factors.

Development of subcortical speech representation in human infants.

Previous studies have evaluated representation of the fundamental frequency (F0) in the frequency following response (FFR) of infants, but the development of other aspects of the FFR, such as timing and harmonics, has not yet been examined. Here, FFRs were recorded to a speech syllable in 28 infants, ages three to ten months. The F0 amplitude of the response was variable among individuals but was strongly represented in some infants as young as three months of age.

Preventing complications in pediatric cochlear implantation.

Purpose Of Review: This review addresses four key areas of controversy in the prevention of common complications of pediatric cochlear implant surgery: reducing meningitis risk, managing acute otitis media (AOM) in the cochlear implant population, assessing the optimum age for implanting a child to take advantage of the critical periods of language acquisition, and managing the social risk in defining ethical issues still surrounding cochlear implant in children.

Recent Findings: Improved surgical techniques and the replacement of Prenvar-7 with Prenvar-13 significantly reduce the risk of cochlear implant related meningitis. AOM within 2 months of cochlear implant placement requires aggressive management to reduce the risk of complication.
