Traumatic sensorineural hearing loss,earring tamil meaning,light ringing in one ear - Try Out

Wearing hearing aids has been such a positive experience for Marie Redfern, she wants to encourage others with hearing loss to try them, too. Your experience can provide helpful information to someone looking for a great hearing care provider, reward a clinic for taking good care of their patients and create a sense of community where you live. Your hearing care professional will identify the type of hearing loss in order to make recommendations about your best treatment options. If a child is born with sensorineural hearing loss, it is most likely due to a genetic syndrome or an infection passed from mother to fetus inside the womb, such as toxoplasmosis, rubella or herpes.
There is no medical or surgical method of repairing the tiny hair-like cells of the inner ear or the auditory nerve if they are damaged. Because the sensitive inner ear and auditory nerve are intact, an individual suffering from conductive hearing loss primarily has difficulty with the overall loudness of sounds, but not the clarity. There are sometimes medical or surgical treatments that can improve hearing ability for those with conductive hearing loss. Conductive hearing losses caused by other abnormalities, like stenosis of the ear canal, exostoses, otosclerosis and ossicular chain discontinuity are more difficult to treat medically and may be considered a permanent hearing loss. The symptoms of mixed hearing loss will be some combination of those listed above for the other two types of hearing loss. Treatment options for mixed hearing loss will depend on whether the loss is more sensorineural or conductive in nature. If you (or your loved ones) think you might have a hearing loss, it's important to consult with a physician and a hearing healthcare professional to investigate the cause and corresponding treatment options.
This is a case study of a 40-year-old male with a sudden profound sensorineural hearing loss experienced secondary to a skull fracture incurred during a violent assault.

The Bert Turner Fund has been established to pay for hyperbaric treatments for patients who are not covered by Medicare or private health insurance, where efficacy is demonstrable and is endorsed by the Undersea and Hyperbaric Medical Society (UHMS), the international watchdog on appropriate uses for hyperbaric medicine. The Fund is run by the Wesley Centre for Hyperbaric Medicine and exists through donations from the public and other hyperbaric patients. If you wish to help others obtain the hyperbaric treatment and care you have received at the Wesley Centre, we would welcome your donation to the Bert Turner Fund. It is a permanent hearing loss that occurs when there is damage to either the tiny hair-like cells of the inner ear or the auditory nerve itself, which prevents or weakens the transfer of nerve signals to the brain.
However, sensorineural hearing loss can be treated quite successfully with hearing aids or cochlear implants, depending on the severity of the loss. Individuals with this kind of loss often find that turning up the volume of the radio or television is all it takes to improve their ability to hear. For example, conductive losses caused by wax impaction, foreign objects, abnormal growths or ear infections can often be corrected with medical treatments, like extraction of earwax, antibiotics or surgical procedures. These conductive losses may be treated with traditional or bone-conduction hearing aids, bone-anchored implantable devices or middle ear implants. If a greater portion of the loss is caused by a conductive component, surgical procedures and other medical treatments might be more effective in correcting the hearing concerns.

Assistive listening devices, like amplified telephones or headphones for television, may help provide a complete hearing solution.
For example, an individual with a long-standing conductive hearing loss might experience presbycusis as they age.
If a greater portion of the loss is sensorineural, hearing aids or implantable devices may be the best option. We invite readers to post comments and questions regarding Edward’s case on the SIG 7 forum and to share their experiences with other cases regarding sudden onset of hearing loss. This case highlights the need to make resources available to the patient, but stresses the importance of a patient-centered approach. The treating physician and hearing healthcare professional will monitor hearing ability and work with the patient to determine when and if a hearing solution is needed. Alternatively, an individual with sensorineural hearing loss may have a temporary mixed hearing loss due to wax impaction. Service providers often think they know what is best for their patients and are frustrated, if not disappointed, when patients do not follow advice. In this case, it became apparent that the patient needed to decide when he was ready to address all of the issues related to his hearing loss and subsequent communication, psychosocial, and vocational difficulties. Local trauma to the tympanic membrane and ossicles can occur by a penetrating injury with objects such as a cotton-tipped applicator, a bobby pin, a pencil, or a hot metal slag during welding . In addition, barotrauma, such as a slap to the ear or a blast injury , can cause a tympanic membrane perforation or ossicular chain dislocation.
This fluid accumulation needs to be drained to prevent chondronecrosis and lead to a misshapen pinna, commonly known as a "cauliflower ear" or "wrestler's ear." After incision and drainage, a compression dressing is sutured through the pinna to bolster the skin and perichondrium against the auricular cartilage, preventing reaccumulation of the fluid. Treatment consists of using an antimicrobial otic drop to prevent bacterial or fungal superinfection of the area.


Alternately, there may be a localized area of blood collection underneath the skin of the external auditory canal, called a bulla. In all cases, patients usually complain of pain and hearing loss, and the perforation can be diagnosed by otoscopy. A central perforation does not involve the annulus of the eardrum, whereas a marginal perforation does. In addition, the Weber tuning fork test should be performed to verify that it radiates to the affected ear, and the eyes should be checked for nystagmus. If the Weber test does not radiate to the affected ear and the patient has nystagmus, it is likely that stapes subluxation with sensorineural hearing loss has occurred. This is termed a perilymphatic fistula and requires urgent treatment (see Perilymphatic Fistula, Treatment).
However, strict dry ear precautions should be followed to prevent water from getting into the ear. Instructions to the patient include no swimming and the use of a cotton ball thoroughly coated with petrolatum (eg, Vaseline) in the affected ear during bathing.
An audiogram should be performed after about 3 months to verify that hearing has returned to normal and that there is no ossicular chain discontinuity. If the perforation has not healed by 3 months, a tympanoplasty will likely need to be performed. Barotrauma, such as a slap to the ear, a blast injury, or rapid decent in an aircraft, can cause ossicular chain dislocation without tympanic membrane perforation.
Ossicular chain dislocation with an intact eardrum manifests as a maximal (60 dB) conductive hearing loss. Ossicular chain dislocation with a perforated eardrum results in lesser degrees of hearing loss.
Treatment in any case is middle ear exploration and ossicular chain reconstruction, with tympanoplasty if needed.
A fracture of the skull base ( otherwise known as a basilar skull fracture) must involve at least one of these bones and may involve all of them.
The most common causes include motor vehicle accidents, falls , bicycle accidents, seizures, and aggravated assaults.
Blunt trauma to the lateral surface of the skull (the squamous portion of the temporal bone) often results in a longitudinal fracture.
A blow to the occipital skull may go through the foramen magnum and result in a transverse fracture of the temporal bone (Figure 591). In contrast, transverse fractures course directly across the petrous pyramid, fracturing the otic capsule, and then extend anteriorly along the eustachian tube and geniculate ganglion. Longitudinal temporal bone fractures and transverse temporal bone fractures represent 80% and 20%, respectively, of temporal bone fractures. Clinical signs include Battle sign, which is a postauricular ecchymosis resulting from extravasated blood from the postauricular artery or mastoid emissary vein.
The "raccoon" sign (periorbital ecchymosis) is associated with basilar skull fractures that involve the middle or anterior cranial fossa. Physical examination may demonstrate an external auditory canal laceration with bony debris within the canal. The Weber tuning fork test radiates to the fractured ear if conductive hearing loss is present and radiates to the contralateral ear if sensorineural hearing loss is present. The presence or absence of facial nerve paralysis should be documented in all patients with temporal bone fractures.
It is critical to rule out an intracranial hemorrhage, which may require urgent neurosurgical treatment.
High-resolution CT scanning of the temporal bone is valuable in delineating the extent of the fracture, but it is not required unless a complication is suspected (eg, otic capsule fracture, facial nerve injury, or CSF leak).
Patients with a longitudinal fracture associated with hemotympanum, without nystagmus, without evidence of CSF leak, with a Weber tuning fork test that radiates to the affected ear, and with normal facial nerve function typically do not need a CT scan of the temporal bone. Angiography may be performed if there is significant hemorrhage from the skull base to rule out vascular injury, but this is uncommon. However, this does not need to be done acutely unless the patient has signs or symptoms of inner ear dysfunction.
If clinical examination is consistent with conductive hearing loss and there is no evidence of otic capsule fracture, audiometric assessment can be performed several weeks after the injury, permitting time for the hemotympanum to resolve.
The rationale is to identify patients with > 90% degeneration of the facial nerve, because these patients have poorer recovery of function and may benefit from surgical decompression .
The nerve excitability test (NET) is performed by placing the two probes of a Hilger nerve stimulator across the stylomastoid foramen and slowly turning up the current until a facial twitch is just barely visible. This involves stimulating both facial nerves with equal currents while simultaneously measuring the evoked myogenic potential in the muscles of facial expression. Neither of these tests is accurate within 3 days of the injury because it takes about 72 hours for nerve fibers distal to the site of the injury to degenerate . The most common form of ossicular discontinuity after temporal bone trauma is incudostapedial joint dislocation. In addition, ossicular fixation may occur several months after the trauma if new bone formation at the line of the fracture fuses to the ossicular chain. This patient had a 60-dB conductive hearing loss with a normal tympanic membrane on physical exam. Note that the fracture runs directly along the geniculate ganglion, but the patient did not have facial nerve dysfunction.
An audiogram usually demonstrates a complete sensorineural hearing loss in the affected ear. Acutely, clinical examination also reveals nystagmus, which is consistent with a unilateral vestibular deficit. Sensorineural hearing loss can also be sustained without otic capsule fracture if a labyrinthine concussion occurs. This is thought to involve shearing of the cochlear membranes or hair cell stereocilia due to the rapid acceleration and deceleration forces within the inner ear.
Finally, patients exposed to traumatic noise exposure or blast injury may sustain a temporary threshold shift in their hearing. This is also felt to be representative of damage to the delicate structures within the inner ear, but this temporary sensorineural hearing loss resolves as these structures recover. The most important clinical feature to identify is whether the facial nerve palsy was of delayed or immediate onset. Patients with delayed-onset palsy present to the emergency room with normal facial nerve function that slowly worsens over the next several hours to days.


This is thought to represent edema within the facial nerve without disruption of neural integrity.
In contrast, immediate facial nerve injury is highly suggestive of facial nerve transection.
Unfortunately, it is common to have an undetermined onset time of facial nerve palsy because patients with temporal bone fractures and facial nerve palsy typically have many other life- threatening issues that are being dealt with at the time of the initial evaluation.
CSF leaks usually start within the first 48 hours of the trauma and are noted as clear fluid emanating from the ear or nose. Eighty percent of post-traumatic CSF leaks close spontaneously after 7 days, and the risk of meningitis is quite low (3%) within this time period. If the leak persists longer than 710 days, the risk of meningitis increases dramatically (2355%). If clear fluid emanating from the nose or ear is suggestive of a CSF leak, the fluid is collected and sent for 2 transferrin testing. The site of a CSF leak from the temporal bone is usually from a fracture in the otic capsule without new callous formation, which can be noted by a CT scan of the temporal bone.
If it is not found on the scan, the injection of an intrathecal contrast during CT scanning often delineates the specific site of the leak. This can sometimes be visible on otoscopic examination of the ear as a white mass with blood vessels behind the tympanic membrane. Traumatic tympanic membrane perforations have an excellent chance of healing spontaneously.
If the perforation has not healed by 3 months, a paper-patch myringoplasty can be attempted in the office. This should be performed only if the perforation is quite small (< 25%) and does not involve the margins of the eardrum and if the middle ear mucosa appears uninfected and dry. The edges of the perforation are freshened with a Rosen needle and a paper patch (cigarette paper or a Steri-strip) is placed over the perforation.
The ossicular chain should also be explored to verify that it is intact during this procedure.
A patient with a normal tympanic membrane and persistent conductive hearing loss probably has ossicular chain discontinuity. A middle ear exploration should be done through the canal by raising a tympanomeatal flap and carefully inspecting and palpating the ossicles. It is expected that 94% to 100% of these patients will have complete and full recovery of their facial nerve function. However, patients with > 90% degeneration of neural integrity have been shown to have poor recovery. Presumably, the nerve is swollen within the bony fallopian canal, compressing itself within this confined space and therefore causing permanent injury to the nerve fibers. Although some neurotologists recommend facial nerve exploration and decompression, others recommend watchful waiting.
These patients should undergo facial nerve exploration as soon as the patient is medically stabilized.
Human studies have not proved that early surgery improves the long- term facial nerve outcome, but animal studies suggest that intervention within 21 days of facial nerve transection is beneficial.
If the patient has normal hearing, a combined middle fossa-transmastoid facial nerve exploration is performed (Figure 594). This includes a subtemporal craniotomy with delineation of the facial nerve within the internal auditory canal from the porus acousticus internus to the geniculate ganglion.
A mastoidectomy is also performed to explore the facial nerve from the middle ear to the stylomastoid foramen. If the patient has a complete sensorineural hearing loss, a translabyrinthine facial nerve exploration and repair can be undertaken (Figure 595). This approach allows for complete exposure of the facial nerve from the porous acousticus to the stylomastoid foramen completely through the mastoid. The middle fossa exposure permits visualization of the nerve from the brainstem to the geniculate ganglion, whereas the transmastoid route exposes the nerve from the geniculate ganglion to the stylomastoid foramen.
In this example, an interpositional facial nerve graft has been placed within the vertical segment of the facial nerve. This approach is used for facial nerve exploration in patients with complete sensorineural hearing loss and allows complete exposure of the nerve through one opening. This includes head elevation, stool softeners, acetazolamide (to decrease CSF production), and the placement of a lumbar drain. Patients with intracranial hemorrhage who have undergone craniotomy often already have an intraventricular drain in place, in which case a lumbar drain is not needed. The most common organisms that cause meningitis in this situation are Pneumococcus, Staphylococcus, Streptococcus, and Haemophilus influenzae. If the patient has normal hearing, the repair of either a persistent CSF leak or an encephalocele is via a combined middle fossa craniotomy-transmastoid approach with suture repair of the dura. In a patient with no useful hearing, obliteration of the ear with an abdominal fat graft, plugging of the eustachian tube, and closure of the ear canal can be performed through the mastoid alone. There is often significant injury to the external auditory canal, which requires local debridement of bone fragments and soft tissue, as well as stenting with Merocel wicks (a type of expandable, nonabsorbable sponge) to prevent stenosis. Tympanic membrane perforation, ossicular discontinuity, and labyrinthine fracture are also common entities with a gunshot wound to the temporal bone. Epithelial elements can be introduced into the mastoid or middle ear cavities and not be detected as a cholesteatoma until years later. Vascular injury is found in 32% of patients with penetrating trauma to the temporal bone; therefore, these injuries should be considered as penetrating trauma to Zone III of the neck and treated accordingly .
Angiography should be performed on all patients, with embolization or balloon occlusion used to control bleeding from the skull base. If the hemorrhage continues or there is evidence of major vessel injury on an angiogram, surgical exploration may be required. In the event that internal carotid artery laceration is found, Fogarty catheters can be used temporarily to control bleeding. Essentially all of these injuries are of immediate onset and occur because of nerve transection. Facial nerve electrophysiologic testing with a Hilger stimulator can be used to identify facial nerve trauma in a comatose patient.
