Imaging of the human cochlea using micro-computed tomography before and after cochlear implantation: comparison with cone-beam computed tomography.

Purpose: Analysis of cochlear structures and postoperative temporal bone (TB) imaging are gaining importance in the evaluation of cochlear implantation (CI°). Our aims were to explore the microarchitecture of human cochlea using micro-computed tomography (μCT), analyze electrode's placement inside cochlea after CI°, and compare pre-/post-implantation μCT scans with cone-beam CT (CBCT) scans of same TBs.

Methods: Cadaveric TBs were scanned using μCT and CBCT then underwent CI° using straight electrodes.

Benign Paroxysmal Vertigo of Childhood. Video Recordings of Episodes.

Objectives: The main objective was to describe the nystagmus observed during benign paroxysmal vertigo (BPV) of childhood, which is one of the criteria included in the three versions of the International Classification of Headache Disorders that has never been specified. The secondary objectives were to emphasize the usefulness of a mobile phone to record nystagmus and discuss the physiopathology of this nystagmus.

Patient: A 6-year-old boy complained of approximately 30 to 50 vertigo attacks, most of them lasting around 1 minute, during a 6-month period.

Balloon dilation for persistent unilateral chronic obstructive Eustachian tube dysfunction is effective: a prospective multicentre study.

Purpose: Balloon dilatation of the Eustachian tube (BDET) is an option for treating chronic obstructive Eustachian tube dysfunction (COETD). In this prospective multicentric study, the main objective was to evaluate the results of BDET in unilateral COETD refractory to medical treatment.

Methods: Adults with unilateral COETD whose Eustachian Tube Score (ETS) was less than 5 despite medical pressure therapy were included.

Clinical Features and Management of Drop Attacks in Menière's Disease. Special Emphasis on the Possible Occurrence of Vertigo After the Drop Attacks.

Introduction: Tumarkin first described drop attacks (DA) in patients with a peripheral vestibular syndrome and speculated the role of a mechanical deformation of the otolith organs. We emphasized on the possible occurrence of vertigo/dizziness after a DA. In the light of the oculomotor examination of one patient right after the DA, we discussed on the mechanisms.

Endonasal endoscopic approach to the pterygopalatine and infratemporal fossae.

The pterygopalatine fossa and infratemporal fossa are spaces located under the skull base, housing important neurovascular structures. Surgical access to these spaces is challenging because of their deep location and complex anatomy. Their surgical access has been classically carried out through multiple craniofacial approaches until the advent of endoscopic endonasal surgery at the end of the XX century.

The French Cochlear Implant Registry (EPIIC): General indicators.

Cochlear and brainstem implants have been included on the list of reimbursable products (LPPR) in France since March of 2009. The implants were initially inscribed for 5 years, after which an application for renewal with the French National Commission for the Evaluation of Medical Devices and Health Technologies (Commission Nationale d'évaluation des dispositifs médicaux et des technologies de santé - CNEDiMTS) was required [Haute Autorité de santé, 2009]. Upon registration to the list of reimbursable products, the companies and the reference centers for cochlear and brainstem implants were asked to set up a post-registration registry called EPIIC.

Unilateral cochleovestibular nerve compression syndrome in a patient with bilateral IAC osteoma.

Introduction: Osteomas of the internal auditory canal are rarely reported in the literature. Patients may complain of disabling symptoms of dizziness, hearing loss, and vestibular dysfunction. We report the case of a patient with bilateral osteomas of the internal auditory canal (IAC) associated with bilateral neurovascular compression mainly affecting the right cochleovestibular nerve (VIII) and right anterior inferior cerebellar artery (AICA).

Materials And Methods: Consecutive articles accepted for publication during the period January 2016 - February 2019 were systematically reviewed. Main goal: descriptive analysis of the citation of P-values and use of the terms "significant", "non-significant" and "suggestive" in Abstracts.

Trans-mastoid approach for cerebrospinal fluid leak repair.

Purpose Of Review: To describe the technique and discuss the advantages and outcomes of the trans-mastoid approach (TMA) for temporal bone cerebrospinal fluid (CSF) leak.

Recent Findings: TMA for CSF leak repair is an alternative to middle cranial fossa approach (MCFA) with less morbidity and good outcomes.

Summary: Persistent CSF leak in the temporal bone whether idiopathic, congenital or acquired, is an indication for surgery.

Acquired medial external auditory canal stenosis, anterior tympanomeatal angle blunting, and lateralized tympanic membrane: Nosology, diagnosis, and treatment.

Objectives: To analyze the etiologies, auditory consequences, diagnostic tools and therapeutic results of three often confused pathologies: acquired fibrous stenosis of the medial part of the external auditory canal (EAC), fibrous anterior tympanomeatal angle blunting, and lateralized tympanic membrane.

Material And Methods: Retrospective study of 18 cases operated on over a 16-year period (14 patients: 7 female, 7 male; aged 11-64 years): 8 cases of medial EAC stenosis, 3 of blunting, and 7 of tympanic membrane lateralization.

Results: In all 3 pathologies, otoscopic and radiologic diagnosis was easily established, so that they could not be confused.

Impact of cochlear implantation on peripheral vestibular function in adults.

Objective: Cochlear implantation may have a detrimental effect on vestibular function and residual hearing. Our goal was to investigate the impact of cochlear implantation on peripheral vestibular function and the symptomatology that ensues.

Material And Methods: A prospective observational study included all adults undergoing cochlear implantation by the same operator between July 2014 and December 2015, with pre- and postoperative (4 months) neurovestibular balance examination comprising a questionnaire and clinical tests [head impulse test (HIT), head-shaking test (HST), skull vibration test (SVT)] and instrumental tests [caloric test of the lateral semicircular canal and cervical vestibular-evoked myogenic potentials (cVEMP)].

Delayed endolymphatic hydrops. Special emphasis on nystagmus associated with episodes and contribution of chemical labyrinthectomy.

Objectives: The main objective was to describe spontaneous nystagmus characteristics during an episode of delayed endolymphatic hydrops (DEH), including an initial vertical upbeating nystagmus in one patient. The secondary objective was to highlight the contribution of chemical labyrinthectomy.

Methods: Episodic vertigo after a prolonged period of time of sensorineural hearing loss (profound or total) in one ear characterized ipsilateral DEH and was associated with the development of hearing loss in the opposite ear in contralateral DEH.

Relationship Between Audio-Vestibular Functional Tests and Inner Ear MRI in Meniere's Disease.

Objectives: Meniere's disease is an inner ear disorder generally attributed to an endolymphatic hydrops. Different electrophysiological tests and imaging techniques have been developed to improve endolymphatic hydrops diagnosis. The goal of our study was to compare the sensitivity and the specificity of delayed inner ear magnetic resonance imaging (MRI) after intravenous injection of gadolinium with extratympanic clicks electrocochleography (EcochG), phase shift of distortion product otoacoustic emissions (shift-DPOAEs), and cervical vestibular-evoked myogenic potentials (cVEMP) for the diagnosis of Meniere's disease.
