Griet Mertens, Annick Gilles, Rajae Bouzegta, Paul Van de Heyning
BACKGROUND: Recently, an adhesive bone conduction hearing system has been developed for conductive hearing loss or single-sided deafness (SSD). In SSD cases, this device may be a good solution for patients who are unsuitable for, or who do not wish to undergo, bone conduction implant or cochlear implant surgery. The study aimed to investigate the hearing outcomes with the adhesive hearing system in SSD. PURPOSE OF THE STUDY: The study aimed to investigate the hearing outcomes with the adhesive hearing system in SSD...

Yun Jung Bae, Jae-Jin Song, Byung Se Choi, Young Kang, Jae Hyoung Kim, Ja-Won Koo
OBJECTIVE: Distinguishing intralabyrinthine schwannoma (ILS) from labyrinthitis is crucial in deciding patient management between surgery and medication; however, the clinical and radiological differentiation between ILS and labyrinthitis is difficult, especially when labyrinthitis shows contrast-enhancement mimicking ILS on magnetic resonance imaging (MRI). This study aimed to evaluate the quantitative characteristics of signal intensity on 3T MRI for differentiating ILS from contrast-enhancing labyrinthitis (CEL)...

Danielle R Trakimas, Elliott D Kozin, Iman Ghanad, Joseph B Nadol, Aaron K Remenschneider
HYPOTHESIS: We hypothesize that human cases of cochlear implantation (CI) with folding of the electrode array will demonstrate greater degrees of intracochlear ossification, lower spiral ganglion neuron (SGN) counts, and poorer audiometric outcomes. BACKGROUND: CI electrode array folding, such folding of the proximal array, is a relatively common surgical complication that can occur with forceful electrode insertion and may be an important and avoidable factor affecting implant outcomes...

OBJECTIVES: Catecholamine-secreting jugular paragangliomas (JPs) represent a rare subset of head and neck paragangliomas that may present with hypertension, arrhythmia, or syncopal episodes. Subtotal resection to protect critical neurovascular structures may result in persistent catecholamine excess from residual tumor. Herein, we report our experience with stereotactic radiosurgery (SRS) for salvage treatment of catecholamine-secreting JP following subtotal microsurgical resection. PATIENTS: Adult patients treated with SRS after subtotal microsurgical resection of catecholamine-secreting JP...

HYPOTHESIS: Methods for cochlear coverage determination vary in their accuracy and are hence not equally reliable. BACKGROUND: The audiological outcome after cochlear implantation is known to depend on several factors. One factor shown to positively correlate with speech perception is the insertion angle. This parameter is one of the ways to describe the fraction of the cochlea spiral exposed to electric stimulation after implantation, also known as cochlear coverage, which itself is dependent on the length and type of electrode array as well as the size and shape of the implanted cochlea...

Brent P Spehar, Jeffery T Lichtenhan
HYPOTHESIS: Persons with normal audiometric thresholds but excessive difficulty hearing in background noise will choose auditory training as a treatment option. BACKGROUND: Auditory training has traditionally been reserved for those with marked hearing loss. We investigated auditory training as a treatment option for those who have normal auditory thresholds but complain about hearing in noise-a population of patients for which no therapy or intervention currently exists...

HYPOTHESIS: Merlin-deficient Schwann cells (MD-SC) and primary human vestibular schwannoma (VS) cells exhibit selective uptake of sodium-fluorescein (SF), allowing for fluorescent detection and improved visualization of tumor cells, when compared with Schwann cells (SC). BACKGROUND: SF is a fluorescent compound used for fluorescence-guided resection of gliomas. The utility of SF for VS surgery has not been assessed. METHODS: Mouse MD-SCs and rat SCs were cultured on 96-well plates at different cell densities and treated with SF at several drug concentrations and durations...

Rahul K Sharma, Stephanie Y Chen, Jedidiah Grisel, Justin S Golub
OBJECTIVE: In the era of big data, it is critical to aggregate results across different institutions. This is a major challenge for cochlear implant (CI) research given multiple, incompatible outcome measures. We use a large, national CI database to develop a formula to convert between the two most common measures: Consonant-Nucleus-Consonant word (CNCw) and Arizona Biomedical (AzBio). We then use this tool to analyze hearing outcomes in older adults with a single, universal outcome measure...

Jordan B Hochman, Justyn Pisa, Bonnie Cham
INTRODUCTION: Cochlear reimplantation procedures account for approximately 5% of all implant cases and may be caused by internal device failure, skin flap complications, or an unexpected decline in auditory performance. This issue, in concert with changing demographics, expanded audiometric candidacy criteria, adult bilateral implantation, and implantation for unilateral hearing loss, all place escalating pressure on device availability and resource allocation in a publically funded health care system...
