The purpose of this study is to evaluate whether the Iowa/Nucleus 10/10 mm in one ear, in conjunction with a Nucleus Freedom implant in the other ear can provide useful binaural hearing in pediatric subjects who have bilateral severe to profound hearing loss and meet the criteria for cochlear implantation. The Iowa/Nucleus 10/10 mm cochlear implant has a short, 10 mm electrode array that it is inserted only into the more basal region of the cochlea. Unlike a conventional cochlear implant, the Iowa/Nucleus 10/10 mm is expected to preserve the regions of the cochlear partition that are apical to the electrode, thus leaving them available for possible future advances in the field of otolaryngology and hearing devices, such as mammalian hair cell regeneration techniques or improved implantable hearing devices. The Iowa/Nucleus 10/10 mm will be implanted in the contralateral ear from the Nucleus Freedom electrode array as a means of providing bilateral stimulation of auditory pathways while preserving the middle and apical regions of the scala media.

The objective of this multisite study is to evaluate the performance of the Nucleus Freedom cochlear implant system in a large population of sequentially implanted pediatric subjects.
This is a prospective, 1:1 randomized controlled trial of immediate versus delayed cochlear implantation (CI) on hearing handicap, communicative function, loneliness, mental wellbeing, and...
This feasibility study evaluates whether children with unilateral, moderate to profound sensorineural hearing loss experience an improvement in speech perception, hearing in noise, localiz...
This is a phase 1 safety study performed in male or female adult participants with an established diagnosis of severe to profound sensorineural hearing loss that meets the criteria for coc...
Cochlear implants require programming on an individual basis to provide appropriate levels of electrical stimulation. This program, or "map", is placed in the speech processor of the cochl...
Effective hearing rehabilitation with cochlear implantation is challenging in developing countries, and this review focuses on strategies for childhood profound sensorineural hearing loss care in Sout...
The relationship between cognition and the ability to hear is well known. Due to changes in demographics, the number of people with sensorineural hearing loss and cognitive impairment is increasing. T...
This systematic review of the literature reveals which pre-operative factors affect sequential cochlear implantation outcomes in adults. The findings can help health care prof-essionals provide eviden...
To examine the possible speech recognition and health related quality of life (HRQoL) benefits of cochlear implantation among adults with asymmetric sensorineural hearing loss.
Pathologic involvement of the inferior cochlear vein is a mechanism of sensorineural hearing loss in patients with jugular foramen paraganglioma.
Hearing loss due to damage or impairment of both the conductive elements (HEARING LOSS, CONDUCTIVE) and the sensorineural elements (HEARING LOSS, SENSORINEURAL) of the ear.
Hearing loss resulting from damage to the COCHLEA and the sensorineural elements which lie internally beyond the oval and round windows. These elements include the AUDITORY NERVE and its connections in the BRAINSTEM.
The cochlear part of the 8th cranial nerve (VESTIBULOCOCHLEAR NERVE). The cochlear nerve fibers originate from neurons of the SPIRAL GANGLION and project peripherally to cochlear hair cells and centrally to the cochlear nuclei (COCHLEAR NUCLEUS) of the BRAIN STEM. They mediate the sense of hearing.
Hearing loss due to disease of the AUDITORY PATHWAYS (in the CENTRAL NERVOUS SYSTEM) which originate in the COCHLEAR NUCLEI of the PONS and then ascend bilaterally to the MIDBRAIN, the THALAMUS, and then the AUDITORY CORTEX in the TEMPORAL LOBE. Bilateral lesions of the auditory pathways are usually required to cause central hearing loss. Cortical deafness refers to loss of hearing due to bilateral auditory cortex lesions. Unilateral BRAIN STEM lesions involving the cochlear nuclei may result in unilateral hearing loss.
Surgical insertion of an electronic hearing device (COCHLEAR IMPLANTS) with electrodes to the COCHLEAR NERVE in the inner ear to create sound sensation in patients with residual nerve fibers.
Hearing, auditory perception, or audition is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Sound may be heard through solid, liquid, or gaseous mat...
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
