OBJECTIVE: We present the clinical findings, technique of the suprameatal cochlear implantation, postoperative auditory results, and genetic analysis of the CHD7 gene. PATIENT: A 19-year-old Japanese woman was referred because of progressive hearing loss since early childhood. She had used verbal language for the main mode of communication until the age of 17. Examination revealed coloboma, heart defect, choanal atresia, genital hypoplasia, and deafness, which was diagnosed as CHARGE syndrome...

OBJECTIVE: To analyze clinical signs and better define the underestimated long-term pain after implantation, to discuss etiological hypothesis, and to propose our department treatment algorithm and results. STUDY DESIGN AND SETTING: Retrospective review of children implanted with complaints of atypical pain in the area of device implantation, not in the immediate postoperative period, more than or equal to 4 on the Visual Analog Pain Scale (VAPS: 0-10) in the ENT pediatric department of Trousseau and Necker Enfants Malades Hospitals between 1998 and 2015...

OBJECTIVES: To compare the diagnostic yield of high-resolution volumetric T2-weighted MRI (HRT2-MRI) with high-resolution computed tomography (HRCT) for diagnosis of large vestibular aqueduct (LVA). STUDY DESIGN: Three board-certified neuroradiologists performed an independent, blinded radiological review for diagnosing LVA with 2:1 age-matched controls on patients with both HRCT and HRT2-MRI imaging. SETTING: Tertiary referral center. PATIENTS: All patients between 2002 and 2016 with hearing loss who underwent both HRCT and HRT2-MRI and were diagnosed with LVA on either modality...

HYPOTHESIS: Drilling on the incus produces intracochlear pressure changes comparable to pressures created by high-intensity acoustic stimuli. BACKGROUND: New-onset sensorineural hearing loss (SNHL) following mastoid surgery can occur secondary to inadvertent drilling on the ossicular chain. To investigate this, we test the hypothesis that high sound pressure levels are generated when a high-speed drill contacts the incus. METHODS: Human cadaveric heads underwent mastoidectomy, and fiber-optic sensors were placed in scala tympani and vestibuli to measure intracochlear pressures (PIC)...

INTRODUCTION: We aimed to study the participation of proprioceptive and visual inputs in subjective visual vertical (SVV) in bilateral vestibular hypofunction and in normal subjects. STUDY DESIGN: Prospective case-control study. SETTING: Tertiary referral center. MATERIALS AND METHODS: SVV (six replicates) was measured on a tiltable rehabilitation seat in 26 adult patients with idiopathic bilateral vestibular hypofunction (IBVH) and 33 adult controls...

HYPOTHESIS: Acoustic stimulation generates measurable sound pressure levels in the semicircular canals. BACKGROUND: High-intensity acoustic stimuli can cause hearing loss and balance disruptions. To examine the propagation of acoustic stimuli to the vestibular end-organs, we simultaneously measured fluid pressure in the cochlea and semicircular canals during both air- and bone-conducted sound presentation. METHODS: Five full-cephalic human cadaveric heads were prepared bilaterally with a mastoidectomy and extended facial recess...

HYPOTHESIS: Effective paramagnetic contrast agent for the penetration of the perilymphatic spaces of the scala tympani, scala vestibuli, and scala media of the mouse inner ear can be determined using intravenous injection of various gadolinium (Gd) complexes and ultra-high-field magnetic resonance imaging (MRI) at 9.4 Tesla. BACKGROUND: A number of contrast agents have been explored in experimental high-field MRI to determine the most effective Gd complex for ideal signal-to-noise ratio and maximal visualization of the in vivo mammalian inner ear in analyzing the temporal and spatial parameters involved in drug penetration of the blood-perilymph barrier and intrastrial fluid-blood barrier in the mouse model using MRI...

HYPOTHESIS: A new generation 192-slice multi-detector computed tomography (MDCT) clinical scanner provides enhanced image quality and superior electrode localization over conventional MDCT. BACKGROUND: Currently, accurate and reliable cochlear implant electrode localization using conventional MDCT scanners remains elusive. METHODS: Eight fresh-frozen cadaveric temporal bones were implanted with full-length cochlear implant electrodes. Specimens were subsequently scanned with conventional 64-slice and new generation 192-slice MDCT scanners utilizing ultra-high resolution modes...

OBJECTIVE: Inflammatory pseudotumor of the temporal bone is a benign, idiopathic inflammatory process that is locally invasive and a cause of significant morbidity. This study reviews our experience with seven patients and is currently the largest series to date. STUDY DESIGN: Retrospective review from January 1, 2014 to January 1, 2016. SETTING: Single tertiary medical center. PATIENTS: There were five male and two female (n = 7) subjects with a diagnosis of temporal bone inflammatory pseudotumor...

BACKGROUND: Cochlear implants (CIs) can improve speech-in-noise performance for listeners with unilateral sensorineural deafness. But these benefits are modest and in most cases are limited to head-shadow advantages, with little evidence of binaural squelch. HYPOTHESIS: The goal of the investigation was to determine whether CI listeners with normal hearing or moderate hearing loss in the contralateral ear would receive a larger head-shadow benefit for target speech and noise originating from opposite sides of the head, and whether listeners would experience binaural squelch in the free field in a test involving interfering talkers...

Joseph H Conduff, Daniel H Coelho
HYPOTHESIS: Medicaid reimbursement rates for cochlear implants and related services fall short of the federal benchmark set by Medicare. BACKGROUND: The financial hardships of cochlear implant centers around the United States may be a repercussion of poor Medicaid reimbursement. In time, these reimbursement discrepancies could force additional Otolaryngologists and cochlear implant centers to not provide these crucial services due to financial limitations. METHODS: Based on Medicare (MCR) claims data, current procedural terminology (CPT) codes used for cochlear implantation and related services were selected...

OBJECTIVE: To compare the efficacy of intratympanic gentamicin injection (ITG) on vertigo control, drop attacks, and functional level in Ménière's disease patients with and without a history of migraine. PATIENTS: Ménière's disease patients (patients with migraine and age- and sex-matched control patients without migraine) treated from 2002 to 2012 who failed medical management and received ITG, with a minimum 2-year follow up.
