..To report and evaluate the results of auditory brainstem implantation in a case of postmeningitis hearing loss with totally ossified cochleae on both sides...

..This study investigates the function of the diastrophic dysplasia sulfate transporter (DTDST) in otosclerotic bone and the effect on it of sodium fluoride (NaF)...

..Fibrin glue is a simple, rapid and efficient means of facial nerve repair. In case of intraoperative facial nerve interruption, this type of repair can be attempted in any location at the time of the tumor removal...

..To assess the bone density around the bony labyrinth in otosclerosis patients and to compare it to that of a control population...

..Of the conservative management group, 17% were lost during follow-up. After surgery, grade 1 or 2 facial function was obtained in 86% of cases. Following hearing preservation attempts (n=137), 54% of patients were in hearing classes A-C...

..01). CONCLUSION: DTDST activity is regulated by estrogens in SaOS-2 cells, but not in primary cell cultures from stapes and EAC. This difference in the regulation mechanisms may be related to the type of estrogen receptor expressed...

..1 ± 2.90 dB before vs. 81.0 ± 3.02 dB after surgery (n = 19, p < 0.01)]. Both Flex arrays allow deep insertion with reproducible hearing preservation...

..The robot-surgeon interface and the command modes are provided. Finally, the system is evaluated by realistic tasks in experimental dedicated settings and in human temporal bone specimens...

..Auditory brainstem responses (ABRs) associated with other audio-vestibular examinations and a thorough clinical examination should allow detection of the majority of cerebellopontine angle (CPA) lesions (99.2-100%)...

..To report the first case of spontaneous intratumoral and brainstem hemorrhage in a patient with a vestibular schwannoma...

..In all the cases, the restoration of a bilateral hearing has to be done if possible, making an improvement of the speech comprehension, mainly in the noisy situations, as well as the localization of the sound sources...

..1 and 0.5 nM) reduced necrosis. These results indicate that HNE and Ang II might act mutually dependently in the regulation of bone cell growth and in the pathophysiology of otosclerosis...

..The recordings showed lower insertion forces beyond 270° of insertion and deeper insertions with the thin prototype array. This will potentially allow larger cochlear coverage with less trauma...

..This phenomenon may be due to haemorrhage or oedema, and can be accompanied by a deterioration of the hearing function. Early surgical resection is the treatment of choice and allows to confirm the diagnosis...

..The aim of this study was to assess the expression and production of inflammation mediators in basal condition and after angiotensin II (AngII) in otosclerosis...

..The maximal EMG response was detected in the frontal or platysma muscles in 26% of cases, and in the orbicularis oris and orbicularis oculi muscles in 74%...

..This simple computer-based drawing tool provides valid information on mental representation of mastoidectomy at its initial phase...

..To detect and localize aquaporin-2 (AQP-2), a water channel regulated by the antidiuretic hormone, in human endolymphatic sac...

..To evaluate speech performance, in quiet and noise, and localization ability in adult patients who had undergone bilateral and simultaneous implantation...
