Sensorineural hearing loss is the most common type of hearing loss, occurring in 23% of population older than 65 years of age.
Infections, such as meningitis, are a common cause of hearing loss in children where it occurs in approximately 20% of those with streptococcus pneumoniae meningitis (Heckenberg et al 2011).
Noise induced hearing loss is a permanent hearing impairment resulting from prolonged exposure to high levels of noise. Children who are born prematurely or contract certain infections in utero are at a higher risk of hearing loss (Hille et al 2007, Roizen 2003). While very unusual, acoustic neuromas or metastatic cancer (particularly breast) can be a source of hearing loss.
Sudden hearing loss (SHL) is defined as greater than 30 dB hearing reduction, over at least three contiguous frequencies, occurring over 72 hours or less.
Sensory presbyacusis is caused by loss of sensory elements in the basal (high-frequency) end of the cochlea with preservation of neurons. Cochlear conductive presbyacusis is caused by thickening of the basilar membrane caused by deposition of basophilic substance. Because presbycusis occurs in some individuals as they age but not in others, genetic or environmental factors must also play a role in its development (Liu & Yan 2007). In conductive hearing loss, the second most common form of hearing loss, sound is not transmitted into the inner ear. Images marked as copyright Northwestern University were developed with the support of a National Institutes of Health (NIH) grant to Northwestern University Dept.
The American Hearing Research Foundation is a non-profit foundation that funds research into hearing loss and balance disorders related to the inner ear and is also committed to educating the public about these health issues.

For example, the audiogram on the left depicts a symmetrical hearing loss and the audiogram on the right depicts an assymetrical hearing loss. Sensorineural hearing losses occur when the "inner" ear or the actual hearing nerve itself becomes damaged.
Sensorineural hearing loss is often referred to as "nerve deafness." Nerve deafness is not really an accurate description because the damage most frequently occurs within the inner ear rather than the hearing nerve.
Idiopathic sudden sensorineural hearing loss (ISSHL), or nerve-related deafness, is the sudden loss of hearing in one or both ears that rapidly occurs within 72 hours or less. The incidence of ISSHL has been reported to affect approximately 20 people out of every 100,000 people per year.
The severity of ISSHL can be mild or severe, short or long-term – regardless of whether it’s in just one ear or both.
Tinnitus (ringing in the ears) is commonly associated with idiopathic sudden sensorineural hearing loss. Developed over 350 years ago, but not readily adopted until the early 1930s when the military tested the use of oxygen as a therapy, hyperbaric chambers were originally used for the purpose of relieving scuba divers of carbon monoxide poisoning or decompression sickness.
Today, increased research has made it possible for hyperbaric oxygen therapy to be used in the treatment of a multitude of FDA and AMA approved illnesses, including idiopathic sudden sensorineural hearing loss.
This increase in oxygen has been medically proven to effectively speed up the healing process if done within the first three months of your hearing loss. Patients young and old lie or sit in a hyperbaric chamber (we offer both monoplace and multiplace chambers) that have been specifically designed for therapy.
Since HBOT is a therapy, your anticipated treatment time will vary depending on just how severe your hearing loss is. Comments and Discussion:Have Your Say: Do you agree, disagree, want to discuss or add an opinion on this topic? The outer ear includes the auricle, the external auditory canal, and the lateral surface of the tympanic membrane (TM).


Postmeningitic hearing loss can be due to lesions of the cochlea, brainstem and higher auditory pathways, but usually is related to suppurative labyrinthitis (cochlear damage).
One in 10 Americans has a hearing loss that affects his or her ability to understand normal speech.
Much research has focused on the detection of genetic causes of hearing loss, and many of them can now be diagnosed at an early age (Blanchard et al 2012, Dror & Avraham 2009, Kochhar et al 2007, Kokotas et al 2007, Robin et al 2005, Xing et al 2007). Risk factors that correlate with hearing loss in premature infants include hypoxia, mechanical ventilation, hyperbilirubinemia, very low birth weight, and the use of ototoxic medications. It occurs most frequently in the 30- to 60-year age group and affects males and females equally. These patients have symmetrical, high-frequency sensorineural hearing loss (as shown in Figure 3). Medical conditions that are common in the elderly, such as diabetes and stroke, may also increase the risk of hearing loss with aging (Bainbridge et al 2010, Helzner et al 2005, Maia & Campos 2005, Schreiber et al 2010). Causes include a buildup of ear wax, a foreign body in the ear canal, otosclerosis, tympanosclerosis (as shown in Figure 4), external or middle ear infections (otitis externa or media), allergy with serous otitis media, trauma to the ossicular chain such as temporal bone fracture, tumors of the middle ear, erosion of the ossicular chain (cholesteatoma) and perforation of the tympanic membrane. Unilateral means hearing loss in one ear, with normal hearing sensitvity in the other ear.
The white area represents the sounds that the person would not hear (softer then their thresholds) and the tan area indicates all of the sounds that the person would be able to hear (louder then their thresholds). About 90% of all people with hearing impairment are in this category, making it the most common type of hearing impairment. Sensorineural hearing loss occurs from damage to the inner ear, the nerve that runs from the ear to the brain (auditory nerve), or the brain. They might experience difficulties with hearing in areas that are noisy, and find it difficult to tell high-pitched sounds such as, 'th,' or, 's,' from one another. The middle ear includes the medial surface of the TM, the ossicular chain, the eustachian tube, and the tympanic segment of the facial nerve. These conditions are relatively common in premature infants, and the majority do not go on to develop hearing deficits. Hearing loss in adults surviving pneumococcal meningitis is associated with otitis and pneumococcal serotype. Race and sex differences in age-related hearing loss: the Health, Aging and Body Composition Study. Thus, "sensorineural" indicates the part of the ear that is malfunctioning and encompasses many different causes for the malfunction. The great majority of human sensorineural hearing loss is caused by abnormalities in the hair cells of the organ of Corti in the cochlea.
People with SNHL may perceive other people's voices as sounding slurred or mumbled, and find it easier to hear men's voices than women's voices. The inner ear includes the auditory-vestibular nerve, the cochlea and the vestibular system (semicircular canals). The National Institute of Health reports that about 15 percent of Americans aged 20 to 69 have high frequency hearing loss related to occupational or leisure activities.
If the loss is minor, then avoidance of noise and ototoxic medications may be an appropriate treatment. Trauma is more likely to affect hearing in patients who suffer a temporal bone fracture or are older in age (Bergemalm, 2003). Because of occupational risk of noise induced hearing loss, there are government standards regulating allowable noise exposure.
As someone who experiences these symptoms due to SNHL, the topic is one that is interesting.The Causes of Sensorineural Hearing LossThe inner portion of a person's ear contains tiny hair cells that are nerve endings. People working before the mid 1960s may have been exposed to higher levels of noise where there were no laws mandating use of devices to protect hearing.


Occasionally, persons with acquired deafness can be treated surgically with a surgically implanted device, a cochlear implant. However, most people with sensorineural loss find wearing hearing aids to be of significant benefit and some people with severe loss can benefit from a cochlear implant. Sensorineural hearing loss (SNHL) is caused by damage to these cells or nerve fibers in a person's inner ear. At times, the hearing loss is caused by damage to the nerves that carry signals to the person's brain.Chart showing causes of acquired sensorineural hearing loss (SNHL) - Post to PinterestSNHL may also be present at the time a person is born referred to as, 'congenital,' although it is most often due to genetic syndromes, or infections the person's mother has passed onto their baby while still in the womb such as herpes, rubella, or toxoplasmosis.
The medications are considered to be, 'ototoxic.' At this time there are greater than 200 known ototoxic medications, both over-the-counter and prescription, on the market. A person's hearing and balance issues caused by these medications might at times be reversed when the medication therapy ends. The health care professional will discuss the effects with the person and how the side-effects will affect their quality of life.The Effects of Ototoxic MedicationsOne of the first effects people tend to notice related to ototoxic medications and hearing loss involves tinnitus. The hearing loss might go unnoticed until the person's ability to understand speech becomes affected, something this writer has personal experience with. Balance issues might also happen as a result of ototoxic medications; a person may experience a loss of balance and a feeling of being unsteady on their feet.
At times these issues are temporary because the person's body may learn to adapt to a reduction in balance control - at other times not.The effects of ototoxic medications have the ability to affect a person's quality of life. An inability to hear conversations, or feeling a bit dizzy, may cause them to cease participation in their usual activities. The effects kind of sneak up on you and before you know it, there they are.Medications that are OtotoxicChart showing certain ototoxic medications - Post to PinterestMore than 200 medications and chemicals are known to cause hearing and balance issues. It is very important to discuss any effects you experience with your health care professional, as well as the potential for hearing or balance damage related to any medication you are taking.
Treatment with a specific medication might provide you with your best hope for curing a life-threatening disease, or ending a life-threatening infection.Medications that are known to cause permanent damage include certain, 'aminoglycoside,' antibiotics such as gentamicin, as well as cancer chemotherapy medications such as carboplatin and cisplatin.
Medications that are known to cause temporary damage include, 'salicylate,' pain relievers such as common aspirin, as well as, 'loop diuretics, and quinine. In some instances, exposure to loud noise while a person is taking certain medications increases their damaging effects.At this time, research is being performed to develop ways to protect people from the ototoxic effects of medications, although there is no approved protective strategy.
It is important for you to monitor your hearing and balance before you start treatment with such a medication.
Before beginning treatment, a baseline record of your hearing and balance should be recorded by an audiologist. The baseline record should include an audio-logic hearing test that uses high-pitched testing, word recognition, as well as other types of testing if possible. I did not receive these types of testing until it was too late.The information can help you and your health care professional to make any important decisions to change or cease the ototoxic medication therapy before you hearing is permanently damaged. In instances when the medication cannot be changed or stopped, you and your audiologist might take steps to manage the effects of the hearing loss that results. During the course of ototoxic medication treatment, you should have periodic hearing tests as a part of the monitoring process, it will help you to report any hearing changes, balance issues, or ringing in the ears you experience.As for me, I now use hearing aids due to the hearing loss I experience. Balance issues are a part of life now for me, although a portion of the balance issues may be due to osteoarthritis. It is my belief that a combination of factors led to the hearing loss I experience, such as the use of heavy NSAID's, antibiotics for a life-threatening infection at one point in my life, and age-related factors.
