OBJECTIVE: Conventional hearing aids have some limitations in overcoming a large air-bone gap or in cases of severe high-frequency hearing loss. The authors aimed to evaluate the benefit of a new bimodal hearing configuration combining cochlear implantation (CI) and middle ear implant (MEI) in patients with severe mixed conductive and ski-slope hearing loss. STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral center. PATIENTS: Four patients with severe to profound hearing loss, who underwent CI in one ear and MEI in the other, were enrolled...

OBJECTIVE: This study aims to provide a clinical evaluation of the Advanced System for Implant Stability Testing (ASIST) for assessment of implant stability for bone-anchored hearing aid patients. We evaluate the longitudinal changes in implant interface stability during the first year following surgery. METHODS: ASIST measurements were collected for 39 patients selected to receive a bone anchored hearing aid for hearing loss. Measurements were collected at the time of surgery and at 3 days, 2 weeks, 1 month, 3 months, 6 months, and 12 months following surgery...

OBJECTIVE: Many studies have published conflicting results regarding the necessity of post-maneuver postural restrictions following treatment of benign paroxysmal positional vertigo (BPPV). The purpose of this meta-analysis is to complete an updated, comprehensive review to determine best practice following a repositioning maneuver (RM). DATA SOURCES: PubMed, CINAHL, and Embase were searched through July 2016. The reference lists of the selected studies were searched for studies that were not identified in the electronic database searches...

: Cockayne syndrome (CS) is a rare autosomal recessive syndrome resulting in defective DNA repair. Its features include cachectic dwarfism, hearing loss, skin hypersensitivity to sunlight, premature aging, and dementia. Presented is a right temporal bone of a patient who died at the age of 29 years. The clinical course was compatible with type 1 CS, the classical form. Homozygous missense variant in the ERCC6 gene (Excision Repair Cross-Complementation group 6) was found, compatible with CS complementation group B...

OBJECTIVE: Semi-automated volume segmentation tools (SAVST) offer a less time consuming technique compared with manual volume segmentation method. No data exists to suggest which of the available applications are optimal for use with vestibular schwannomas (VS).

Christina L Runge, Fang Du, Yi Hu
OBJECTIVE: Electrical stimulation with a cochlear implant (CI) elicits abnormally high neural synchrony, which poses significant challenges for speech perception. Previous investigations showed that constant-amplitude high-rate pulse trains (HRPs) desynchronize neural responses and improve stimulus encoding. The study objective was to investigate the effects of HRP on speech perception in adult CI users. STUDY DESIGN: Prospective, within-subject design. SETTING: Tertiary CI center...

BACKGROUND: The oval window is an important structure with regard to stapes surgeries, including stapedotomy for the treatment of otosclerosis. Recent study of perioperative imaging of the oval window has revealed that oval window niche height can indicate both operative difficulty and subjective discomfort during otosclerosis surgery. With regard to shape, structures incorporated into the oval window niche, such as cartilage grafts, must be compatible with the shape of the oval window...
