#1
Michael S Harris, Lauren Boyce, David B Pisoni, Valeriy Shafiro, Aaron C Moberly
HYPOTHESIS: 1) Environmental sound awareness (ESA) and speech recognition skills in experienced, adult cochlear implant (CI) users will be highly correlated, and, 2) ESA skills of CI users will be significantly lower than those of age-matched adults with normal hearing. BACKGROUND: Enhancement of ESA is often discussed with patients with sensorineural hearing loss as a potential benefit of implantation and, in some cases, ESA may be a major motivating factor. Despite its ecological validity and patients' expectations, ESA remains largely a presumed skill...

OBJECTIVE: To describe the presentation and management of surgical emphysema involving the temporomandibular joint and deep neck following exostoses removal. PATIENT: A 60-year-old male surfer presented with hearing loss and recurrent infections in the right ear. An examination revealed obstructing bony exostoses in the right external auditory canal. He underwent right canalplasty using a postauricular approach. At 5 weeks after surgery, he presented with right otalgia, swelling of the right face and neck, and complaints of a squeaking noise in the right ear with mandibular excursions...

OBJECTIVE: Although visual processing recruitment of the auditory cortices has been reported previously in prelingually deaf children who have a rapidly developing brain and no auditory processing, the visual processing recruitment of auditory cortices might be different in processing different visual stimuli and may affect cochlear implant (CI) outcomes. METHODS: Ten prelingually deaf children, 4 to 6 years old, were recruited for the study. Twenty prelingually deaf subjects, 4 to 6 years old with CIs for 1 year, were also recruited; 10 with well-performing CIs, 10 with poorly performing CIs...

BACKGROUND: High-resolution computed tomography (HRCT) magnifies the role of preoperative imaging for detailed inner and middle ear anatomical information and enhances more efforts for better dependent correlation and measurements of round window (RW). OBJECTIVE: To find an applicable way by HRCT imaging for the prediction of the visibility of the RW during cochlear implantation (CI) surgery. METHODS: Five radiologic measurements were performed on the axial HRCT and these measurements were correlated with the degree of RW visibility after performing posterior tympanotomy during CI surgery...

HYPOTHESIS: To propose a new objective video-recording procedure to assess and monitor over time the severity of facial nerve palsy. BACKGROUND: No objective methods for facial palsy (FP) assessment are universally accepted.

HYPOTHESIS: Depth of insertion is related to the extent of tissue response and low frequency hearing loss. Intravenous steroids have greatest effect in reducing postimplantation fibrosis and hearing loss in the presence of significant electrode insertion trauma, when compared with saline treatment. BACKGROUND: Experiments exploring the enhancement of cochlear implantation (CI) outcomes with glucocorticosteroids have produced mixed results, possibly due to lack of standardization of the CI model...

HYPOTHESIS: Internal jugular vein (IJV) compression influences not only intracranial but also intracochlear physiology and has demonstrated preclinical effectiveness in reducing acute audiological injury in a rodent blast model. However, the long-term effects in this model are unknown. BACKGROUND: Blast wave-induced audiological injury from an improvised explosive device is a leading cause of morbidity among service members in theater but there are limitations to the current protective measures...

INTRODUCTION: Stimulation of the cochlear round window (RW) with the floating mass transducer (FMT) still suffers from large variation in clinical outcomes. Beside the geometric mismatch between RW and FMT diameter that is a known limiting factor in achieving optimal coupling between actuator and RW membrane, the applied static force between FMT and RW is usually undefined. In this study, the feasibility and efficacy of a specially designed FMT coupler permitting application of static preloads to the RW membrane to optimize FMT-RW coupling was investigated...
