OBJECTIVES: To determine if the OOPS index is predictive of long-term hearing results after ossiculoplasty. STUDY DESIGN: Case series with retrospective chart review. SETTING: Tertiary care otology practice. PATIENTS: Adult and pediatric patients (3-88 years of age). INTERVENTIONS: Ossiculoplasty with cartilage tympanoplasty, with or without mastoidectomy. OUTCOME MEASURES: Primary outcome measures included short-term hearing results (pure-tone average air-bone gap [PTA-ABG] measured between 60 days and 1 year after surgery), long-term hearing results (PTA-ABG measured ≥5 years after surgery), and the rate of successful ABG closure to ≤20 dB...

OBJECTIVES: Intraoperative electrocochleography (ECochG) provides valuable information regarding inner ear function during surgical procedures. Here, we report findings from ECochG collected at three time intervals during the management of a patient with symptoms of inner ear hydrops. PATIENTS: A 38-year-old man with an endolymphatic sac tumor who demonstrated classic Ménière's symptoms. INTERVENTIONS: Endolymphatic shunt, tumor biopsy, and definitive resection of an endolymphatic sac tumor...

HYPOTHESIS: Internal jugular vein (IJV) compression before blast injury will lead to reduced risk of traumatic hearing injury following exposure to a blast injury. BACKGROUND: IJV compression and its effects on not only intracranial, but also intracochlear pressure may potentiate blast induced hearing injury, therefore, precluding its use as a prophylactic therapy for blast induced traumatic brain injury. METHODS: Twenty Sprague Dawley rats were exposed to a 17...

HYPOTHESIS: We hypothesize that current clinical treatment strategies for the disarticulated or eroded incus have the effect of combining the incus and stapes of the human middle ear (ME) into one rigid structure, which, while capable of adequately transmitting lower-frequency sounds, fails for higher frequencies. BACKGROUND: ME damage causes conductive hearing loss (CHL) and while great progress has been made in repairing or reconstructing damaged MEs, the outcomes are often far from ideal...

OBJECTIVE: Compare incidences of complications following implantation of osseointegrated bone conduction devices (OBCD) between children with and without behavioral disorders. STUDY DESIGN: Case series with chart review. SETTING: Tertiary referral center otology and neurotology practice. PATIENTS: Pediatric patients who underwent implantation of OBCD between May 2009 and July 2014 at Arkansas Children's Hospital.

OBJECTIVE: There is no consensus regarding the benefit of implantable hearing aids in congenital unilateral conductive hearing loss (UCHL). This study aimed to measure sound source localization performance in patients with congenital UCHL and contralateral normal hearing who received a new bone conduction implant.

HYPOTHESIS: An image-guided robotic system can safely perform the bulk removal of bone during the translabyrinthine approach to vestibular schwannoma (VS). BACKGROUND: The translabyrinthine approach to VS removal involves extensive manual milling in the temporal bone to gain access to the internal auditory canal (IAC) for tumor resection. This bone removal is time consuming and challenging due to the presence of vital anatomy (e.g., facial nerve) embedded within the temporal bone...

OBJECTIVE: We assessed whether the three-dimensional fluid-attenuated inversion-recovery (3-D FLAIR) and three-dimensional inversion-recovery with real reconstruction (3-D real IR) sequences can be used to detect cochlea endolymphatic hydrops (EHs) in guinea pigs using 3 Tesla magnetic resonance imaging (3T MRI). The results of 3-D real IR imaging were compared with histopathological outcomes. MATERIALS AND METHODS: Fourteen healthy men and women albino guinea pigs were used in this study...

OBJECTIVE: The correlation between the isosorbide-induced decompression effect on the endolymphatic space and plasma osmolality (p-OSM) or plasma arginine vasopressin (p-AVP) was investigated on comparing two different dosages of isosorbide (2.8 and 1.4 g/kg) to elucidate why the decompression effect is delayed with a large dose of isosorbide. MATERIALS AND METHODS: Two experiments were performed using 80 guinea pigs. Experiment 1 was designed to morphologically investigate the sequential influence of the oral intake of 1...

OBJECTIVE: The bone-anchored hearing aid (BAHA) Attract is a transcutaneous bone conduction hearing aid that uses magnetic coupling to enable sound conduction. We report the first case of skin necrosis associated with the BAHA Attract and perform a literature review of soft tissue complications related to the device. PATIENT: A single patient who was found to develop skin necrosis 2 weeks after being fitted for the BAHA Attract speech processor. INTERVENTION: After the patient developed skin necrosis from the device, she was advised to immediately discontinue use of the Attract to allow complete wound healing, upon which the Attract was successfully converted to a percutaneous BAHA...

HYPOTHESIS: To investigate the intracranial abnormalities present in children with cochlear nerve deficiency (CND), including abnormalities of other cranial nerves, and to describe their auditory abilities. BACKGROUND: The prevalence of CND has increased with the development of high resolution magnetic resonance imaging (MRI). There are varying degrees of CND from true aplasia to hypoplasia. The etiology of CND remains unclear and it may be associated with intracranial abnormalities in some instances...

OBJECTIVE: Demonstrate safety and effectiveness of the light-driven contact hearing aid to support FDA clearance. STUDY DESIGN: A single-arm, open-label investigational-device clinical trial. SETTING: Two private-practice and one hospital-based ENT clinics. PATIENTS: Forty-three subjects (86 ears) with mild-to-severe bilateral sensorineural hearing impairment. INTERVENTION: Bilateral amplification delivered via a light-driven contact hearing aid comprising a Tympanic Lens (Lens) with a customized platform to directly drive the umbo and a behind-the-ear sound processor (Processor) that encodes sound into light pulses to wirelessly deliver signal and power to the Lens...

OBJECTIVE: To analyze somatic and psychological factors affecting the outcomes of in-hospital vestibular rehabilitation in patients with intractable dizziness. MATERIALS AND METHODS: The study involved 138 patients with persistent dizziness caused by peripheral vestibular dysfunction. They were hospitalized and taught to conduct a vestibular rehabilitation program for 30 minutes by themselves three times a day over 5 days. They were then instructed to continue performing the program every day after discharge...

OBJECTIVE: Vestibular dysfunction is a well-recognized complication of type 2 diabetes (DM) that may contribute to increased fall risk. The prevalence of benign paroxysmal positional vertigo (BPPV) is higher in people with DM. The impact of DM on the otolith organs of the vestibular system in people with BPPV is unknown. The purpose of this study was to analyze otolith function using vestibular-evoked myogenic potential (VEMP) tests in people with DM and concurrent BPPV (BPPV + DM), and to examine the relationships between VEMP variables and diabetes-related variables...

OBJECTIVES: To describe the fluctuating high velocity vestibular ocular-reflex (VOR) during the Ménière's attacks and correlate those features with pathophysiology. PATIENTS: A patient with unilateral Ménière's disease (MD) was evaluated closely during and after acute vertigo episodes. MAIN OUTCOME MEASURES: The spontaneous nystagmus and the dynamic VOR changes were measured by the video head impulse test (VHIT) at different stages of the vertigo crisis and during the quiescent phase of the condition...
