This study aims to examine the mechanism of damage to the basilar membrane caused by the proximal section of the cochlear implant electrode array. ⋯ Results from this study are useful for cochlear implant surgeons in better understanding the mechanism of damage by the electrode array's proximal section to the basilar membrane and in establishing advanced insertion techniques for reducing the damage (in particular, the results strongly support the "advance off-stylet" technique). The outcomes of the study also are beneficial for cochlear implant designers in selecting appropriate stiffness profiles for future electrode arrays, which are expected to cause minimal damage to the basilar membrane (a new design of the contour array with stiffness increasing from the front to the proximal section is highly recommended).

To review the current literature to assess the effectiveness of rehabilitation treatment for peripheral facial nerve palsy. ⋯ Peripheral injury of the VIIth cranial nerve can have serious repercussions on the patient's functioning and quality of life. The recovery rate is related to the preservation of the nerve and to the cause of palsy. We obtained a third level of recommendation (level C); mime therapy could be effective to improve functional outcome in these patients. Evidence of specific treatment addressed to specific cause is lacking; likewise, no evidence is available on timing of intervention with respect to time of onset. Well-designed randomized controlled trials are required to evaluate the effect of rehabilitation in patients with facial palsy.
