OBJECTIVE: Controlled and uncontrolled studies with primary intratympanic or combined intratympanic and systemic application of glucocorticosteroids for idiopathic sudden hearing loss were analyzed by means of a meta-analysis in an attempt to establish optimal local drug delivery protocols. STUDY DESIGN: A total of 25 studies with 28 treatment groups between January 2000 and June 2014 were selected that adequately described drug delivery protocols. Cochlear drug levels were calculated by a validated computer model of drug dispersion in the inner ear fluids based on the concentration and volume of glucocorticoids applied, the time the drug remained in the middle ear, and the specific timing of injections...

OBJECTIVE: To determine if cranioplasty techniques following translabyrinthine approaches to the cerebellopontine angle are cost-effective. STUDY DESIGN: Retrospective case series.

INTERVENTION: Cranioplasty with a dural substitute, layered fat graft, and a resorbable mesh plate secured with screws Main Outcome Measures: billing data was obtained for each patient's hospital course for translabyrinthine approaches and postoperative cerebrospinal fluid (CSF) leaks...

OBJECTIVE: To compare the outcome of hearing rehabilitation in younger versus older adult cochlear implant recipients. Analysis of surgical and postoperative complications, as well as the number of auditory therapy sessions in the two age groups. STUDY DESIGN: Individual retrospective cohort study. METHODS: A cohort of 145 postlingually deafened adults was evaluated in this study. The patients were divided into two age groups based on the age at implantation: Group I, 18 to 69 years; and Group II, 70 and older...

OBJECTIVE: Describe the diagnosis and management of spontaneous lateral skull base cerebrospinal fluid (CSF) leaks that originate from the posterior fossa. STUDY DESIGN: Retrospective case review. SETTING: Tertiary university hospital. PATIENTS: Adult patients from 2005 to 2015 who underwent surgical repair of a spontaneous lateral skull base CSF leak with intraoperative confirmation of a posterior fossa leak source...

OBJECTIVE: To investigate the prevalence of vestibular schwannoma (VS) and asymmetric sensorineural hearing loss in the Veterans Administration hospital population and analyze a more efficient method of diagnosing VS in a population with significant noise exposure. STUDY DESIGN: Retrospective review of South Central (VISN 16) Veterans Administration hospitals. METHODS: Record query for ICD-9 codes for asymmetric sensorineural hearing loss or VS between 1999 and 2012...

OBJECTIVE: To investigate the accuracy of rigid cochlear models in measuring intra-cochlear positions of cochlear implant (CI) electrodes. PATIENTS: Ninety three adults who had undergone CI and pre- and postoperative computed tomographic (CT) imaging. MAIN OUTCOME MEASURES: Seven rigid models of cochlear anatomy were constructed using micro-CTs of cochlear specimens. Using each of the seven models, the position of each electrode in each of the 98 ears in our dataset was measured as its depth along the length of the cochlea, its distance to the basilar membrane, and its distance to the modiolus...

AIM: The aim of this study is to gain insight into the disease progression and behavior of primary cholesteatoma in a cohort of patients who did not have surgery using non-echoplanar diffusion-weighted magnetic resonance imaging (DW MRI) serial monitoring. METHODS: Retrospective longitudinal observational study of 12 cases of middle ear cleft cholesteatoma diagnosed between 2009 and 2014 where surgery was not performed for various reasons. All cases were monitored radiologically with non-echoplanar half-Fourier acquisition single-shot turbo spin-echo diffusion weighted imaging annually for a median period of 23 months (between 11 and 45 mo) to evaluate for changes in disease volume and direction of growth...

HYPOTHESIS: Scala tympani morphology influences the insertion dynamics and intra-scalar position of straight electrode arrays. BACKGROUND: Hearing preservation is the goal of cochlear implantation with current thin straight electrode arrays. These hug the lateral wall, facilitating full, atraumatic insertions. However, most studies still report some postoperative hearing loss. This study explores the influence of scala tympani morphology on array position relative to the basilar membrane and its possible contribution to postoperative hearing loss...

OBJECTIVE: The eustachian tube (ET) has two important functions, ventilation and clearance of the middle ear. We evaluated the ET ventilator function by the sonotubometry and the inflation-deflation test that are widely used today, and the ET clearance function by the saccharin test. Results of both tests were compared with surgical outcomes, and assessed which test was more closely related to the surgical outcomes. STUDY DESIGN: Prospective case series. SETTING: A single university hospital...

OBJECTIVE: To evaluate the ability of ultra-high-field magnetic resonance imaging (UHF-MRI) at 11.7 T to visualize membranous structures of the human inner ear. SPECIMENS: Three temporal bones were extracted from cadaveric human heads for use with small-bore UHF-MRI. INTERVENTION: Ex vivo cadaveric temporal bone specimens were imaged using an 11.7 T magnetic resonance imaging (MRI) scanner via T1- and T2-weighted-imaging with and without contrast...

INTRODUCTION: In Internet forums and other social media many reports regarding chronic headaches after cochlear implantation can be found. Although quite rare, there are also some reports in the literature. However, little is known regarding the true prevalence of headaches in persons who have undergone cochlear implant surgery. OBJECTIVES: The primary aim of this study was to investigate the 1-year prevalence of headache in patients having received a cochlear implantation ("cochlear implant group") in comparison with patients having undergone middle ear surgery ("surgery group") and persons with no history of head and neck surgery ("non-ear-nose-throat [ENT] group")...
