The effect of angulation of the vibrating floating mass transducer on stapes velocity.

Hypothesis: Changes to the angular position of the vibrating floating mass transducer (FMT) coupled to the long process of the incus will not affect stapes velocity.

Objective: The MED-EL Vibrant Soundbridge is an active middle ear implantable device, which constitutes an effective alternative to acoustic hearing aids for the rehabilitation of patients with sensorineural and mixed hearing loss. Because of varied anatomy, it is not always possible to position the FMT in line with the vibrating axis of the stapes.

De novo development and progression of endolymphatic sac tumour in von hippel-lindau disease: an observational study and literature review.

Endolymphatic sac tumors (ELST) are rare invasive lesions of the temporal bone that are commonly associated with von Hippel-Lindau disease. This report describes serial magnetic resonance imaging (MRI) and computed tomography (CT) findings over a period of 6 years in a 12-year-old patient who developed an ELST after 3.5 years surveillance for a cerebellar hemangioblastoma.

The atretic plate--a conduit for drill vibration to the inner ear?

Conclusion: In the presence of simulated congenital aural atresia with fixation of the ossicular chain to the surrounding bone, access to the chain for placement of a middle ear prosthesis using the rotating burr is not associated with significant stapes movement that would cause vibrational trauma to the cochlea.

Objectives: To determine the energy transmitted to the cochlea while drilling the mastoid in an ear with simulated congenital aural atresia and fixation of the ossicular chain to the surrounding bone.

Methods: Eight human cadaveric temporal bones were used.

Systematic review of cochlear implantation in children with developmental disability.

Objective: To perform a systematic review comparing the xoutcome of cochlear implantation in children with developmental disability with children without developmental disability.

Data Sources: MEDLINE, EMBASE, and Cochrane databases were searched from 1950 or the start date of each database. The search was performed on 1st November 2012, and included articles published ahead of print with no language restrictions.
