Effects of Remaining Hair Cells on Cochlear Implant Function

Second Quarterly Progress Report NO1-DC-9-2106 Effects of Remaining Hair Cells on Cochlear Implant Function

Evaluation of Saccular Function Pre-Post Cochlear Implant Surgery Using VEMPs

Objectives: The aim of present study was evaluation of saccule function in cochlear implant candidates with severe to profound sensory neural hearing loss Before and after cochlear implantation Methods: In this study 35 cochlear implant (CI) candidates with bilateral severe to profound sensory neural hearing loss before and about 30 days after cochlear implant and 20 normal-hearing cases as ...

The Cochlear Implant

The studies on cochlear implants have been conducted in the United States, Austria, Brasil, France, Finland, and some other countries. Up to now, this technique does not seem to have a wide spread application. Indeed it can only apply cases of deafness still presenting sufficient neural remnants to transmit the message. Moreover, the patient must be totally deaf( quasi­ complete loss of har cel...

Potential of Pluripotent Stem Cells for the Replacement of Inner Ears

The inner ear, which manages our senses of hearing and balance, has mechanosensitive hair cells, which convert vibration into electronic signal to depolarize auditory or vestibular neurons. Inner ear functions depend largely on hair cells, their associated neurons and cochlear lateral wall, and defects in these cells result in hearing loss and deafness. Although some investigations indicated ha...

Therapeutic potential of cell therapy in the repair of hair cells and spiral ganglion neurons: review article

The mammalian cochlea is a highly complex structure which contains several cells, including sensory receptor or hair cells. The main function of the cochlear hair cells is to convert the mechanical vibrations of the sound into electrical signals, then these signals travel to the brain along the auditory nerve. Auditory hair cells in some amphibians, reptiles, fish, and birds can regenerate or r...
