Tight fixation of stapes prostheses yields better functional results because sound transmission from the incus to prosthesis is improved. Background: The optimal use for otosclerosis surgery still a matter debate. It has been proposed that using made Nitinol, shape-memory metal, produces with less variability and reduced risk middle inner ear damage. This thought be heat activation rather than manual crimping loop forms tighter fixation. Methods: Functional two groups were compared 1 year...

(1) To correlate simultaneously recorded intra- and extracochlear electrocochleography (ECochG) signals during electrode insertion into the cochlea, (2) to track changes in ECochG signal removal of an electrode, (3) findings with preoperative residual hearing. We hypothesized that intracochlear recordings show not reflected simultaneous recordings.During cochlear implantation human implant recipients, a short, slim, custom-made was inserted removed stepwise manner. At each step, were by near...
Abstract We aimed to determine the prevalence of radiological temporal bone features that in previous studies showed only a weak or an inconsistent association with clinical diagnosis Meniere’s disease (MD), two groups MD patients (n = 71) previously established distinct endolymphatic sac pathologies; i.e. group MD-dg (ES degeneration) and MD-hp hypoplasia). Delayed gadolinium-enhanced MRI high-resolution CT data were used compare between within (affected vs. non-affected side) geometric...
The aim of this multicentre, prospective, open, nonrandomised clinical trial was to demonstrate the efficiency and outcomes cochlear implants (CIs) in adult patients with post-lingual single-sided deafness (SSD).
The aim of this investigation was the assessment normal facial movements using objective computer-assisted OSCAR method.
