OBJECTIVES/HYPOTHESIS: To report a series of patients with neurofibromatosis type 2 (NF2), where each patient underwent both cochlear implantation and auditory brainstem implantation for hearing rehabilitation, and to discuss factors influencing respective implant success. STUDY DESIGN: Retrospective case series. METHODS: Ten NF2 patients with both cochlear implantations and auditory brainstem implantations were retrospectively reviewed. Speech testing for auditory brainstem implants (ABIs) and cochlear implants (CIs) was performed separately...

OBJECTIVE: To study the quality and usability of magnetic resonance imaging (MRI) obtained with a cochlear implant magnet in situ. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary care center. PATIENTS: All patients who underwent brain MRI with a cochlear implant magnet in situ from 2007 to 2016. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Grade of view of the ipsilateral internal auditory canal (IAC) and cerebellopontine angle (CPA)...

OBJECTIVE: We sought to assess the complication rates following cochlear implantation in canal wall down mastoid cavities in adults and children. DATA SOURCES: A systematic review of English articles from PubMed, Web of Science, EMBASE, and the Cochrane Library. Additional studies were identified by reviewing the reference lists of the originally identified studies. REVIEW METHODS: Studies were included that reported on surgical outcomes following cochlear implantation in canal wall down mastoid cavities...

OBJECTIVES: The purpose of this study was to review the indications for subtotal petrosectomy for cochlear implantation, report our management of complications, as well as review those technical factors that are critical for successful implantation. METHODS: Patients (n = 104) that underwent subtotal petrosectomy with closure of the external auditory canal and obliteration of the cavity with abdominal fat in combination with cochlear implantation were analyzed. RESULTS: The most frequent indication for subtotal petrosectomy was the existence of a previous canal wall down technique...

This article is the second in a 2-part series reviewing neuroimaging in childhood SNHL. Previously, we discussed the clinical work-up of children with hearing impairment, the classification of inner ear malformations, and congenital nonsyndromic causes of hearing loss. Here, we review and illustrate the most common syndromic hereditary and acquired causes of childhood SNHL, with an emphasis on entities that demonstrate inner ear abnormalities on cross-sectional imaging. Syndromes discussed include BOR syndrome, CHARGE syndrome, Pendred syndrome, Waardenburg syndrome, and X-linked hearing loss with stapes gusher...

SNHL is a major cause of childhood disability worldwide, affecting 6 in 1000 children. For children with prelingual hearing loss, early diagnosis and treatment is critical to optimizing speech and language development, academic achievement, and social and emotional development. Cross-sectional imaging has come to play an important role in the evaluation of children with SNHL because otolaryngologists routinely order either CT or MR imaging to assess the anatomy of the inner ears, to identify causes of hearing loss, and to provide prognostic information related to potential treatments...

IMPORTANCE: The association between hearing impairment and cognitive decline has been established; however, the effect of cochlear implantation on cognition in profoundly deaf elderly patients is not known. OBJECTIVE: To analyze the relationship between cognitive function and hearing restoration with a cochlear implant in elderly patients. DESIGN, SETTING, AND PARTICIPANTS: Prospective longitudinal study performed in 10 tertiary referral centers between September 1, 2006, and June 30, 2009...

PURPOSE OF REVIEW: To examine the current literature regarding application of cochlear implantation in patients with single-sided deafness for improvement in sound localization. RECENT FINDINGS: As familiarity of the technical and biological capabilities of cochlear implantation improves and criteria for use broaden, investigators have begun examining usage of cochlear implantation in patients with single-sided deafness as a viable solution in attempts to improve sound localization and speech perception...
