Cochlear electrode reimplantation in the guinea pig.
Cochlear implants are being applied to an ever widening patient population, including children in whom lifetime use of these devices is anticipated. Replacement of implants can be expected for reasons of device failure as well as future upgrading. This investigation was undertaken to examine the effect of cochlear electrode explanation and reimplantation on spiral ganglion cell survival. Guinea...
متن کاملInfluence of electrode array stiffness and diameter on hearing in cochlear implanted guinea pig
During cochlear implantation, electrode array translocation and trauma should be avoided to preserve residual hearing. The aim of our study was to evaluate the effect of physical parameters of the array on residual hearing and cochlear structures during insertion. Three array prototypes with different stiffnesses or external diameters were implanted in normal hearing guinea pigs via a motorized...
متن کاملAdult cortical plasticity studied with chronically implanted electrode arrays.
The functional architecture of adult cerebral cortex retains a capacity for experience-dependent change. This is seen after focal binocular lesions as rapid changes in receptive field (RF) of the lesion projection zone (LPZ) in the primary visual cortex (V1). To study the dynamics of the circuitry underlying these changes longitudinally, we implanted microelectrode arrays in macaque (Macaca mul...
متن کاملRound window electrocochleography before and after cochlear implant electrode insertion.
OBJECTIVE/HYPOTHESIS Previous reports have documented the feasibility of utilizing electrocochleographic (ECoG) responses to acoustic signals to assess trauma caused during cochlear implantation. The hypothesis is that intraoperative round window ECoG before and after electrode insertion will help predict postoperative hearing preservation outcomes in cochlear implant recipients. STUDY DESIGN...
متن کاملIsosorbide Concentration in Perilymph of the Guinea Pig After Oral Administration Versus That After Round Window Perfusion
OBJECTIVES The aims of this study were to investigate the feasibility of isosorbide delivery into perilymph through the round window membrane (RWM), and to compare the intracochlear isosorbide concentration in perilymph after oral administration (PO) versus that after round window perfusion (RWP). METHODS Sixteen male guinea pigs (32 ears) were used. Isosorbide, an osmotic diuretic, was admin...
