OBJECTIVES/HYPOTHESIS Cochlear nerve stimulation using a linear array of electrodes, the cochlear implant, has become an accepted treatment for profound deafness. Major limitations of this technology are high threshold of stimulation, poor performance in a noisy background, cross-talk between electrodes, unsatisfactory channel selectivity, and variable(More)
OBJECTIVE To determine whether baseline hearing loss increases cognitive decline and risk for all-cause dementia in a population of elderly individuals. STUDY DESIGN Longitudinal cohort study. SETTING Community-based, outpatient. PATIENTS Men and women aged 65 years or older without dementia at baseline. INTERVENTION(S) All subjects completed the(More)
The lack of an adequate standardized method for reporting level of hearing function in clinical trials has hampered the ability of investigators to draw comparisons across studies. Variability in data reported and presentation format inhibits meta-analysis and makes it impossible to accumulate the large patient cohorts needed for statistically significant(More)
OBJECT The object of this study was to evaluate facial nerve outcomes in the surgical treatment of large vestibular schwannomas (VSs; ≥ 2.5 cm maximal or extrameatal cerebellopontine angle diameter) based on both the operative approach and extent of tumor resection. METHODS A PubMed search was conducted of English language studies on the treatment of(More)
OBJECTIVE To perform a systematic review, comparing hearing outcomes of atresiaplasty versus osseointegrated bone conduction device (OBCD) in congenital aural atresia (CAA) patients. DATA SOURCES Approximately 107 studies, published from 1975 to 2012, evaluating hearing outcomes after atresiaplasty and/or OBCD in CAA patients were identified through a(More)
Adenomatous tumors in the middle ear and temporal bone are rare but highly morbid because they are difficult to detect prior to the development of audiovestibular dysfunction. Complete resection is often disfiguring and difficult because of location and the late stage at diagnosis, so identification of molecular targets and effective therapies is needed.(More)
BACKGROUND Patients with large vestibular schwannomas are at high risk of poor facial nerve (cranial nerve VII [CNVII]) function after surgery. Subtotal resection potentially offers better outcome, but may lead to higher tumor regrowth. OBJECTIVE To assess long-term CNVII function and tumor regrowth in patients with large vestibular schwannomas. METHODS(More)
OBJECTIVE For older patients (>65 years) who undergo surgical treatment of vestibular schwannoma (VS), the reported rates of facial nerve preservation, hearing preservation, and complications are inconsistent. Many surgeons believe that older patients have worse outcomes than their younger counterparts and advise against surgical treatment. We analyzed a(More)
