Before 1964, electrocochleography (ECochG) was a surgical procedure carried out in the operating theatre. Currently, the newest application is also an intra-operative one, often carried out in conjunction with cochlear implant surgery. Starting in 1967, the recording methods became either minimal- or not-invasive, i.e., trans-tympanic (TT) or extra tympanic (ET), and included extensive studies of the arguments pro and con. I will review several valuable applications of ECochG, from a historical point of view, but covering all 75 years if applicable...

BACKGROUND: Surgical management of Ménière's disease (MD) is recommended in case of medical and intratympanic treatment failures. Translabyrinthine vestibular nerve section has been considered the gold standard for denervation procedures in order to control vertigo attacks, although at the cost of sacrificing residual hearing. To the best of our knowledge, no work has been published with regard to a group of patients submitted to translabyrinthine vestibular neurectomy and simultaneous cochlear implant for MD...

The exact pathomechanism of deafening in Meniere's disease (MD) is still unknown; intoxication of hair cells and neural damage from endolymphatic hydrops is discussed. In the literature, there are only a few reports on hearing outcome of MD patients after treatment with cochlear implantation (CI) whereby especially the comparison of MD vs. non-MD patients with CI differs. In this retrospective study, results in speech understanding [Freiburger Einsilber (FES65) and Hochmair-Schulz-Moser test in quiet (HSM) and in noise (HSM + 10 dB)] of 27 implanted MD patients were collected and compared to a matched standard CI cohort...

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...
