When the Cochlear Nerve is damaged; no form of hearing aid for sound amplification, or even a Cochlear Implant will replace hearing lost.
However, the Auditory Brainstem Implant (ABI) is an option to consider for a chance to restore hearing. Hearing loss is frequently a result of rupturing the Eardrum or one of the three tiny bones.
CN8 - Vestibulocochlear Nerve: As this Central Nerve leaves the center of the brain it splits in half to become the Vestibular Nerve and the Cochlear Nerve. This nerve branch off of CN8, goes to the Cochlea (Spinal Ganglion) and is the nerve specifically for hearing. Vestibular Schwannoma can also damage Cranial Nerve 7, the Facial Nerve, due to proximity of the vestibular nerve.
The facial nerve can easily be broken or otherwise weakened, during treatment management of VS. Treatments might include different surgical approaches for removal of a tumor, some form of radiation treatment, or chemotherapy.
Individuals, who are told they have NF2, but do not develop VS, may in fact have NF3 also known as Schwannomatosis. On the left, the schematic shows an inner hair cell, with its hair bundle at one end and with three of its roughly 20 synapses with cochlear nerve terminals at the other end. The Eustachian tube is labelled in the diagram at the top of this page as the auditory tube. The function of the Eustachian tube is to equalise pressure between the middle and out ear, preventing damage to the tympanic membrane as a result of changes in air pressure. Insect have a membrane,A  the tympanum stretched across a frame with an air sac behind it.A  Vibrations are detected by an receptor called a chordotonal organ. The lateral line of the European Roach (left).A A  The structure of the lateral line showing a neuromast (right). The Eustachian tube is labelled in the diagram at the top of this page as the auditory tube.A  The tube is usually closed but can open to allow a small volume of air to pass between the middle ear (the area between the tympanic membrane and the oval window) and the nasal cavity. The function of the Eustachian tube is to equalise pressure between the middle and out ear, preventing damage to the tympanic membrane as a result of changes in air pressure.A  We become aware of the Eustachian tube when our ears a€?popa€? when ascending or descending a steep mountain in a car or changing altitude in an unpressurised aircraft.
The cochlea and semi-circular canals (associated with the detection of motion).A  Notice the oval window (vestibular fenestra) and round window (cochlear fenestra).
Another possibility is to do with the size of the organs producing the sound.A A  It would be very difficult for a sparrow to be able to produce the frequencies used by elephants because their bodies are so small. Identify the direction from which sound is coming is called sound localisation.A  Mammals a number of different methods of localising sound, including timing the difference between arrival times at the ear. When Schwannoma type tumors grow on the Vestibular Nerve, which effects balance, they are referred to as Vestibular Schwannoma. If damage to the face itself causes severe pain or numbness, damage to Cranial Nerve 5, the Trigeminal Nerve may also be an issue. Vestibular Schwannoma, Schwannoma tumors along Cranial Nerve 8, are an issue that develops in many individuals with NF2.
Cranial Nerve 8 travels a similar path as Cranial Nerve 7 (the Facial Nerve), extending out of the brainstem right next to each other. The facial nerve branches off to smaller nerves and muscles that go to 5 different parts of the face. The nerves in the picture on the right show where on the face, outside of the skull, that the nerve branch extends out. Talking: The same nerves that make eating difficult can also make properly or clearly pronouncing certain letters hard to do. Nerves that are a part of the Central Nerve System (CNS) do not heal as easily as nerves in other areas of the body.
Natural healing that might take place will not visually be seen till about 4 to 6 months after the damage occurs. Vitamin B12: Vitamin B12 is important in the formation of all cells in the body, especially red blood cells and the covering of nerve cells (myelin). Facial nerve physical therapy can consist of different types of treatments which should be discussed with a physical therapist.
Acupuncture helps to stimulate blood to flow back to the different nerves in the face to encourage movement. During surgery if the nerve is only damaged or some attempt to simply reconnect the nerve is done, some amount of healing will take place naturally with help from just physical therapy and time. A Free Muscle Transplant is when a healthy "extra" muscle and transplanting it somewhere else in the body. Tumors that grow on the nerves that effect hearing and balance tend to push on the Facial Nerve which follows a similar path inside the brain. During different tumor management techniques used to preserve hearing and balance the Facial Nerve is lost. Facial Nerve damage can also cause Diplopia (Double Vision or Lazy Eye), as well as Nystagmus and Oscillopsia. This branch affects the glands for tear production and mucous membrane of the nasal cavity.
Joseph reckoned it would take less than three hours for the tree to absorb the flyzard's nutrients.
He thought of the bedraggled puffer crouching in the corner of the lab aviary, mangled and dying.
The foremen howled with laughter as McIntyre bowed, a toothy grin spreading beneath his moustache. Cal glanced at the crippled puffer-owl behind the transparent wall of the aviary, luminous eyes studying its captors as if they were the ones in a cage. Joseph's laughter rang against the walls, bold and unfettered for the first time since his arrival on Kelvyn. The pulverizers were roaring at full capacity when Joseph and Cal reached the edge of the clearing zone.


Joseph stared at the stocky crew chief, knew with sick certainty that the man would not back down.
One section of the colony structure and three pulverizers were demolished while the crews slept. Joseph knew little of his own Cherokee heritage: only scraps culled from thousands of history disks he had searched over the years. Cal shamed McIntyre into letting Joseph out the next morning after it happened for the second time. A mogre slipped from the splintered tree line on six powerful legs, drawn into the open by the scent of death. The two men jogged toward the temporary sleep-cubes where McIntyre and most of the foremen bedded down.
Marsalis glanced at the ruins of the crew chief's cubicle, then nodded with obvious relief. Joseph and Cal were in the lab four hours later when the last shuttle blasted off for the Surveyor. Cal studied Joseph with a new expression in his eyes: surprise, admiration, a trace of fear. The two men stopped just inside the stand of trees that marked the boundary of the village. Cal was a slender man, but he managed to sling Joseph over his shoulder and stagger back toward camp. Cal sank to the ground in exhaustion, breath coming in strangled gasps, and laid Joseph beside him.
The upper image shows eight inner hair cells from a normal ear (each cell has one large red nucleus) and about 150 small red dots (arrowheads), each of which shows a synapse between a hair cell and a cochlear nerve fiber. Therefore, when the nerve is damaged those smaller veins are not supplied with enough blood for circulation which is necessary for muscles on the different areas of the face to move.
Temporal & Zygomatic Branch: Together these Nerve Branches affect the muscles control opening and closure of the Eye. There are things that can be done to help the nerve heal that should be considered when a nerve might or has been damaged. Everyone is different, so it might take more or less time for different people, but the majority of the healing that will occur on its own will be in the first year.
Pain or any other feeling, numbness or lack of feeling in the face is the result of damage of Cranial Nerve 5 (CN5), the Trigeminal Nerve. Each tree was a scale model of the forest, supporting a complete ecosystem within its massive coils. He was in better shape than anyone else in the Surveyor's crew, but the strong gravity of Kelvyn still sapped the strength from his muscles. Skin and bones would drop to the forest floor, where scavengers feasted on the porcu-pine's leavings.
A mousipede crouched in the grass near the center of the clearing, nibbling on the fruit of a bloodberry bush.
A broad pair of forewings and a smaller pair of hindwings controlled their speed and direction of flight. Joseph could not see the creatures hidden behind the leaves, but their terror and confusion buffeted him in waves. He searched the work zone for Angus McIntyre and spotted the crew chief near a field console, poring through schematics with a cluster of foremen.
It didn't take long to locate McIntyre, but the noise made it impossible to talk in the open. He read of the Busk, the festival celebrating first fruits and new fires, but the words had no flavor. The essence of what the Cherokee had been eluded him, like the dappled outline of a lightning-buck darting through morning mist. He looked more like a cornered animal than the puffers that circled above him, singing their silent rage. They fell to the ground, Joseph clawing for the laser, McIntyre still trying to aim at the retreating puffers.
He had been up most of the night, haunted by ghastly visions of Shaman erupting into flame. For a moment he was gliding through the ancient forests of America with his ancestors - strong and unbowed - sinews stretching down into the fragrant soil like roots. Immunostain recognizes a molecule present in the nucleus and also in a key synaptic component within the hair cell, called a "ribbon".
The bottom image shows another ear a few days after exposure to a noise that caused only a transient threshold elevation.
The nerve damage will unlikely be completely restored on its own but there are some options to consider to help maximize the amount of healing.
Yet the rustle of leaves, the fragrance of vegetation, the spring of living carpet beneath his feet offered familiar comfort. He took three swallows from his water pack and watched in fascination as a nearby porcu-pine lured its prey.
It scurried halfway to the tree line on its dozen stubby legs before the puffer's talons dug into its back.
He wriggled between the loops of a corkscrew so his presence would not disturb the puffers. I also know that Corporate is rattlin' their saber a little louder every day, and it's not your head'll be rolling if we fall behind. When we rape a world, it's never the same again; it dies of shame and misery, then it rots around us until we leave. He read of Sequoya and others who tried to adapt to the white man's customs, hoping to salvage some shred of their culture. The tension in his body unwound as the three of them ambled through the maze of plasteel and titanium toward the far edge of the site.


An ugly purple bruise bloomed on one cheek; a split lip bulged beneath the bushy moustache now matted with blood. Massive crocodilian jaws snapped up the tenderest chunks, crushing them to pulp as they vanished into its maw. These men did not fear anything in the galaxy they could see, but an invisible enemy was too much for them. I've reviewed every scrap of seismic data I have, and there's just nothing out of the ordinary about this chunk of rock. Then the crippled puffer-owl spread his speckled wings, inflated, and vanished into the sky. This is the heart of the mechanical-to-electrical transduction process in the inner ear."How did hidden hearing loss remain "hidden" so long?
Corkscrew ferns twisted toward the sky in tightly bunched loops all around him, giant fronds feathering out to catch the orange sunlight. He felt in tune with the rhythms of nature here, reconnected to the threads of growth and life woven into the very fabric of his soul.
A brown flying-lizard not much bigger than a pigeon hovered between the branches, drawn by the aroma of honeysap that oozed from the porcu-pine's bark.
It squeaked twice as its captor flipped it and sliced through its tender belly with a scythe-like beak.
Well, now, there's a thrivin' colony on that planet, and I don't believe a one of them that built it spent a slim second in lockup.
The roar of the pulverizers swelled, much tamer now that half their number had been reduced to scrap. We've only five pulverizers left as it is, and the lads can't make any progress with this commotion. Before Joseph could react, a rod of light leapt from McIntyre's hand into the mass of puffers. Shackled by the roustabouts, Joseph could only shout to drive the demonic creature back into the forest. He's dead and buried… just a few hours after you told him he oughta haul ass out of here for his own safety. He saw the same wonder in Cal Benton's eyes that he himself had felt when he first walked among the corkscrews. I better get you back so we can drug you up good… and so I can jabber some double-talk at Marsalis. They had been chased away by a ghoul with hair the color of blood and a moustache of flame. There are two key reasons, according to Liberman."First, the field of auditory neuroscience didn't appreciate until recently that you can lose up to 90 percent of your cochlear nerve fibers without a change in the ability to detect a tone in quiet," he said.
Eight interminable months trapped in the sterile shell of the Surveyor had almost driven him mad… but the land restored him.
As soon as the flyzard touched the sticky sap, the branches snapped together, impaling it with a dozen needles. A few minutes passed before the bloated outline of a puffer-owl glided from the upper branches.
Because of the strong surface gravity of Kelvyn, they could not get off the ground without the buoyancy of their flight bladders.
Far beyond his vision, a clan of puffer-owls had built their living chambers, piling section upon section as family and home grew together, intertwined.
He barely missed an outstretched porcu-pine branch as he labored back the way he had come, legs pumping against the iron grip of Kelvyn, black hair dancing in the wind.
It floated across the glade with silent stealth, riding the wind like a feathered zeppelin. These inflated with hydrogen extracted from the air when the owls rose, swelling them like balloons. When he staggered into the clearing near the camp, ten pulverizers were already online, gobbling the forest and turning it to mulch. McIntyre followed their gaze, stroking a bushy red moustache that burned like fire in the orange light. But the fact is, we've got to finish the shell structure here and be hyperspatial toward Avalon inside of two months, or it's my ass.
After a few weeks with the pulverizers, we'd flattened half their hunting territory and driven most of the game away. Maybe this planet has some weird localized tectonics, some kind of seismic hiccup we haven't detected yet. The fact that thresholds may transiently elevate and then recover within hours or days after an acoustic overexposure doesn't mean that the inner ear has recovered."Second, the most vulnerable part of the neuron turns out to be the synapse between the nerve terminal and the hair cell, and it happens to be difficult to see. I programmed the computer to scan the ultrasonic frequencies, and there it was: they have a musical vocabulary, pitched so high that the human ear can't detect it. Soon Shaman's village would be a memory, and here he sat like a caged animal, cut off from the sweet breath of the land… unable to stop the slaughter of a way of life.
They wheeled overhead, diving and snapping at the crews, filling the air like a plague of feathered locusts. Without warning he whipped it down across his legs, driving the needles deep into his thighs before collapsing with a cry.
Survivors climbed frantically above the inferno, but McIntyre kept firing, setting off a dozen smaller explosions.
This enabled them to view a large number of synapses on hair cells in a normal ear, as well as the greatly reduced numbers of synapses hair cells following a noise exposure that caused only a transient elevation of thresholds. Liberman and colleagues counted synapses on thousands of hair cells."Each missing synapse represents a cochlear nerve fiber that has been disconnected due to retraction of the terminal segment—it will never reconnect," Liberman noted.
