Sensironeural Hearing Loss
Over 466 million people worldwide suffer from disabling hearing loss, defined as hearing loss greater than a 40dB in the better ear, of which 34 million are children. Sensironeural hearing loss is when a patient’s inner ear is damaged such that sounds are no longer transmitted to, or only partially transmitted to the auditory nerve from the cochlea. This is due to lost or damaged hair cells in the cochlea, that would stimulate the auditory nerve in normal hearing.
The standard of care for sensorineural hearing loss is a cochlear implant.
