BACKGROUND: Dehiscence syndromes of the semicircular canals are a relatively new group of neurotological disorders. They have a variety of symptoms with hearing/balance involvement. Younger patients have clinically relevant symptoms in only about one third of cases. In addition to etiology and pathogenesis, the present paper describes diagnostic and therapeutic possibilities using a patient series of the authors. MATERIALS AND METHODS: This nonrandomized prospective study included 52 patients with uni-/bilateral dehiscence syndromes of the superior and/or posterior canal (SCDS/PCDS), diagnosed with high-resolution computed tomography (HR-CT) of the petrous bone...

Menière's disease (MD) is a chronic multifactorial disorder of the inner ear characterized by episodic vestibular symptoms associated with sensorineural hearing loss, tinnitus, and aural pressure. Epidemiologic and genomic evidence supports a genetic susceptibility with multiple biochemical pathways involved, including the endocrine system, innate immune response, and autonomic nervous system. Allergens, infectious agents, vascular events, or genetic factors could modify inner-ear homeostasis and trigger MD...

OBJECTIVE: Labyrinthectomy is considered the "gold standard" in the treatment of intractable vertigo attacks because of Ménière's Disease (MD) but sacrifices all residual hearing. Interest in auditory rehabilitation has lead to cochlear implantation in some patients. Concern remains that the cochlear lumen may fill with tissue or bone after surgery. This study sought to determine the incidence of obliteration of the cochlea after transmastoid labyrinthectomy. STUDY DESIGN: Retrospective observational study...

Objective: Due to the natural aging and the loosened CI-implantation criteria more formerly operated Meniere's patients will be supplied with a cochlear implant. However, it raises the question whether an implantation in a previously treated ear is promising. Material and Methods: Based on 2 cases in which we have carried out a CI-implantation, one of them 10 years after transmastoidal labyrinthectomy, and based on the current literature we draw attention to problems and prospects of success. Discussion: Histological studies show only a small ossification of the cochlea after labyrinthectomy...

PURPOSE: The purpose of this investigation was to compare the rate of high jugular bulb (HJB) in relation to internal acoustic meatus (IAM), round window (RW) and endolymphatic sac and to study their clinical implications. METHODS: Eighty-seven cadaveric non-pathologic human temporal bones were micro-dissected to expose the jugular fossa (JF) and RW. The minimum distance of JF from RW was measured. On the inner surface of petrous part of temporal bone, minimum vertical distance of JF from IAM and saccus endolymphaticus (E sac) was also measured...

Mutations of COCH can cause hearing loss and less frequently vestibular symptoms. However, vestibular phenotypes, especially in terms of the location of specific variants are not well documented yet. In this study, a retrospective and prospective cohort survey was performed in two tertiary referral hospitals to demonstrate vestibular phenotypes of DFNA9 subjects with a focus on the relationship with the location of COCH mutations. Two DFNA9 subjects were recruited from the previously collected cohort, each segregating p...

BACKGROUND: A dilemma occurs in the treatment of second-sided Ménière's disease in the only hearing ear, particularly in patients with severe symptoms such as 'drop attacks'. This paper describes a patient treated with contralateral cochlear implantation prior to vestibular nerve section of the symptomatic ear. CASE REPORT: A 53-year-old man, with second-sided Ménière's disease and drop attacks in the only serviceable right ear, underwent successful left cochlear implantation 30 years after hearing loss, followed by right vestibular nerve section...

OBJECTIVES: Few studies have addressed the benefits of cochlear implantation for the small group of patients with bilateral, end-stage Meniere's disease, or unilateral disease with contralateral hearing loss from another cause. Our retrospective study evaluates the effectiveness and post-operative performance in these Meniere's disease patients and discusses these findings relative to other post-lingually deafened adults. METHODS: Among 456 adults who received cochlear implants, we identified eight (1...

OBJECTIVES: describe the results of a retrospective study of cochlear implantation (CI) in seven subjects with Menière's disease. METHODOLOGY: The subjects received either the Nucleus CI24RE(CA)/CI512 or the Advanced Bionics HiRes90K CI systems which use the ACE, MP3000, or HiRes S Fidelity 120 coding strategies. The audiometric measures included monosyllabic word lists (NVA) in quiet at 65 dB SPL and sentences in noise (LIST) at +10 dB SNR. The quality of life after implantation was assessed by means of the Nijmegen Cochlear Implant Questionnaire (NCIQ)...

OBJECTIVE: A significant portion of the Ménière's disease (MD) population will ultimately have severe-to-profound hearing loss in their affected ear. When this occurs bilaterally or when a patient has poor hearing in the contralateral ear, these patients may meet criteria for cochlear implantation (CI). Here, we describe our institution's CI outcomes in MD patients. STUDY DESIGN: Retrospective chart and literature review. SETTING: Tertiary referral center...

BACKGROUND/OBJECTIVES: Ménière's disease (MD) that results in bilateral severe to profound sensorineural hearing loss is a rare indication for cochlear implantation; only a few studies exist documenting performance in these patients. The primary objective was to compare the difference in preoperative to 12-month postoperative speech perception scores among subjects with MD and controls. Groupwise comparisons of secondary postoperative outcomes (Tinnitus Handicap Inventory [THI] scores, 36-Item Short Form [SF-36] scores, and postoperative dizziness) were also performed...

HYPOTHESIS: A functional vestibular prosthesis can be implanted in human such that electrical stimulation of each semicircular canal produces canal-specific eye movements while preserving vestibular and auditory function. BACKGROUND: A number of vestibular disorders could be treated with prosthetic stimulation of the vestibular end organs. We have previously demonstrated in rhesus monkeys that a vestibular neurostimulator, based on the Nucleus Freedom cochlear implant, can produce canal-specific electrically evoked eye movements while preserving auditory and vestibular function...
