OBJECTIVE To analyze predictive factors of outcome after ossiculoplasty using a standard ossicular prosthesis system. STUDY DESIGN Retrospective review of 140 ossiculoplasties, performed by the same senior surgeon, with titanium prostheses. SETTINGS Academic hospital and tertiary referral center. PATIENTS All patients undergoing ossiculoplasty with(More)
CONCLUSIONS Hearing may be conserved in adults after implantation with the Nucleus Contour Advance perimodiolar electrode array. The degree of hearing preservation and the maximum insertion depth of the electrode array can vary considerably despite a defined surgical protocol. Residual hearing combined with electrical stimulation in the same ear can provide(More)
Research into visual prosthetics is expected to revolutionize the treatment of blind patients with incurable outer retinal degenerative disease. Substantial evidence shows that useful visual sensations can be produced by controlled electrical stimulation of the optic nerve. To make the optic nerve visual prosthesis more acceptable, implantation techniques(More)
The simultaneous recording of the electrocochleography (ECoG) and the brainstem-evoked responses (BER) enables the I-V interval to be known easily and thus increases the reliability and prognostic value of electrophysiologic measurements of the auditory system. The correlation between the first negative peak of the action potential (N1 in ECoG) and the wave(More)
We examined a group of 115 patients suffering from tinnitus and have attempted to find a statistically significant correlation between the tinnitus experienced and low blood zinc levels (hypozincemia). No particular correlation could be made between the nature of the tinnitus experienced and hypozincemia except for the continuation of head noises, these(More)
Fifty patients with otosclerosis and tinnitus were studied for the course of the tinnitus after stapes surgery. Tinnitus disappeared in 64% of the cases, improved in 16%, was unchanged in 14%, and worsened in 6%. The reduction in tinnitus was more favorable after a small fenestra stapedotomy than after a partial stapedectomy with removal of the posterior(More)
OBJECTIVE This study was designed to identify the 58-kDa inner ear protein against which the sera of some patients with idiopathic, progressive sensorineural hearing loss or Ménière's disease strongly react. BACKGROUND We and other groups have previously demonstrated that a 58-kDa protein extracted from guinea pig or bovine inner ear tissue is a target of(More)
