Decision making about the amplification options may be difficult, particularly in patients with a hypoplastic
cochlear nerve.

cochlear nerve canal and the
cochlear nerve," Pediatric Radiology, vol.
In our case, we verified the integrity of the
cochlear nerves with electrocochleography.
The researchers found no long-term problems such as degradation of function of the device or over stimulation of the
cochlear nerve.
Cochlear implants (CIs) are electronic hearing devices that transform mechanical sound energy into electrical signals and enable hearing by directly transmitting the signals to the
cochlear nerve via an electrode array inserted in the cochlea.
One child with severe inner ear malformation i.e., Michel's deformity with hypoplastic
cochlear nerve on the left side, and Mondini deformity on right side, was excluded.
Alignment was adjusted so that the axial line between the apex of the cochlea and the
cochlear nerve was parallel to the cutting plane.
Each patient received a caloric test, vestibular-evoked myogenic potential (VEMP) test, and
cochlear nerve function test (hearing) before the operation and 1 week, 3, and 6 months, postoperatively.
The motion of fluid in the cochlea stimulates hair cells in the Organ of Corti which, in turn, generate action potentials that are transmitted via the
cochlear nerve through the central auditory pathway to the auditory cortex.
The toddler was born completely deaf in both ears -- without a cochlear (hearing portion of the inner ear) and a
cochlear nerve.
Schwannomas arising from the
cochlear nerve and confined to the internal auditory canal are rare.
