Types, Causes and Treatment
Hearing loss can be caused by many different causes, some of which can be successfully treated with medicine or surgery, depending on the disease process.
Three Types of Hearing Loss
Conductive hearing loss - when hearing loss is due to problems with the ear canal, ear drum, or middle ear and its little bones (the malleus, incus, and stapes).
Sensorineural hearing loss (SNHL) - when hearing loss is due to problems of the inner ear, also known as nerve-related hearing loss.
Mixed hearing loss - refers to a combination of conductive and sensorineural hearing loss. This means that there may be damage in the outer or middle ear and in the inner ear (cochlea) or auditory nerve.
Conductive Hearing Loss
Causes:
Malformation of outer ear, ear canal, or middle ear structures
Fluid in the middle ear from colds
Ear infection (otitis media - an infection of the middle ear in which an accumulation of fluid may interfere with the movement of the eardrum and ossicles
Allergies
Poor Eustachian tube function
Perforated eardrum
Benign tumors
Impacted earwax
Infection in the ear canal
Foreign body in the ear
Otosclerosis
Treatments of Conductive Hearing Loss:
Types of conductive hearing loss include congenital absence of ear canal or failure of the ear canal to be open at birth, congenital absence, malformation, or dysfunction of the middle ear structures, all of which may possibly be surgically corrected. If these are not amenable to successful surgical correction, then the hearing alternatively may be improved with amplification with a bone conduction hearing aid, or a surgically implanted, osseointegrated device (for example, the Baha or Ponto System), or a conventional hearing aid, depending on the status of the hearing nerve.
Other causes of conductive hearing loss are: infection; tumors; middle ear fluid from infection or Eustachian tube dysfunction; foreign body; and trauma (as in a skull fracture). Acute infections are usually treated with antibiotic or antifungal medications. Chronic ear infections, chronic middle fluid, and tumors usually require surgery. If there is no response to initial medical therapy, infectious middle ear fluid is usually treated with antibiotics -- while chronic non-infectious middle ear fluid is treated with surgery (or pressure equalizing tubes).
Conductive hearing loss from head trauma is frequently amenable to surgical repair of the damaged middle ear structures, performed after the patient’s general medical status is stabilized following acute traumatic injuries.
A genetic form of conductive hearing loss is otosclerosis, in which there is bony fixation of the stapes (the third little bone of hearing in the middle ear), where sound can’t get to the middle ear. Otosclerosis usually presents with hearing loss in early adulthood. Otosclerosis can successfully be managed with surgery to replace the immobile stapes with a mobile stapes prosthesis or with a hearing aid. Research suggests that the measles virus may contribute to stapes fixation in those with a genetic predisposition to otosclerosis. The incidence of otosclerosis may be decreasing in some communities due to measles vaccination. Otosclerosis (a hereditary disorder in which a bony growth forms around a small bone in the middle ear, preventing it from vibrating when stimulated by sound) usually causes a conductive hearing loss, a hearing loss caused by a problem in the outer or middle ear. Less frequently, otosclerosis may cause a sensorineural hearing loss (damaged sensory cells and/or nerve fibers of the inner ear), as well as a conductive hearing loss.
Sensorineural Hearing Loss
Causes:
Exposure to loud noise
Head trauma
Virus or disease
Autoimmune inner ear disease
Hearing loss that runs in the family
Aging (presbycusis)
Malformation of the inner ear
Meniere’s Disease
Otosclerosis - a hereditary disorder in which a bony growth forms around a small bone in the middle ear, preventing it from vibrating when stimulated by sound.
Tumors
Treatment of Sensorineural Hearing Loss:
Sensorineural hearing loss can result from acoustic trauma (or exposure to excessively loud noise), which may respond to medical therapy with corticosteroids to reduce cochlea hair cell swelling and inflammation to improve healing of these injured inner ear structures.
Sensorineural hearing loss can occur from head trauma or abrupt changes in air pressure such as in airplane descent, which can cause inner ear fluid compartment rupture or leakage, which can be toxic to the inner ear. There has been variable success with emergency surgery when this happens.
Sudden sensorineural hearing loss, presumed to be of viral origin, is an otologic emergency that is medically treated with corticosteroids.
Bilateral progressive hearing loss over several months, also diagnosed as autoimmune inner ear disease, is managed medically with long-term corticosteroids and sometimes with drug therapy. Autoimmune inner ear disease is when the body’s immune system misdirects its defenses against the inner ear structures to cause damage in this part of the body.
Fluctuating sensorineural hearing loss may be from unknown cause or associated with Meniere’s Disease. Symptoms of Meniere’s disease are hearing loss, tinnitus (or ringing in the ears), and vertigo. Meniere’s disease may be treated medically with a low-sodium diet, diuretics, and corticosteroids. If the vertigo is not medically controlled, then various surgical procedures are used to eliminate the vertigo.
Sensorineural hearing loss from tumors of the balance nerve adjacent to the hearing nerve, generally are not reversed with surgical removal or irradiation of these benign tumors. If the hearing loss is mild and the tumors are very small, hearing may be saved in 50 percent of those undergoing hearing preservation surgery for tumor removal.
Sensorineural hearing loss from disease in the central nervous system may respond to medical management for the specific disease affecting the nervous system. For example, hearing loss secondary to multiple sclerosis may be reversed with treatment for multiple sclerosis.
Irreversible sensorineural hearing loss, the most common form of hearing loss, may be managed with hearing aids. When hearing aids are not enough, this type of hearing loss can be surgically treated with cochlear implants.
Mixed Hearing Loss
Treatments for Mixed Hearing Loss
Audiologist Mark Ross, Ph.D., recommends taking care of the conductive component first. There have been times when the addition of the conductive component made the person a better hearing aid candidate, by flattening out the audiogram for example, while the underlying sensorineural component presented a high-frequency loss. However, still the emphasis would be on treating medically what can be treated. He says that, generally, you would expect positive results.

Hi, thanks for this awesome article, I’m Shania Kubisch 41 and from Manteca CA, USA. i was first diagnosed of Meniere’s disease in 2009 following an unexpected attack. My husband didn’t know what it was and i was taken to the hospital where we were told that i had meniere's disease. It lasted 2 years and went away. It came back in 2012 with a vengeance spinning 24/7, constantly feeling sick, tinnitus in my right ear, and loss of hearing. I was so devastated as i watched my carrier as a cashier crumble and communication with my family and friends lowered. After years of going to the ENT, and search for cure that proved abortive, my husband found out in a post on a health forum about some guru man (Prof Aafiya) who casts herbal healing spells to heal all kind of diseases. My family needed me and i needed a cure at all cost, i and my husband agreed to try the healing spell too and he complained my health state to the spell guru (prof Aafiya) on +2348108647815. He surely did help me and my husband cast a healing spell for Meniere's and i was completely healed of the disease just within 14 days. It’s been 2 years and 7 months since i had the healing spell and i have not had any symptoms of meniere’s disease. My hearing has been fully restored instantly and everything is back to normal again. If you have meniere's disease and experiencing it symptoms, you too may be able to get help from this Man (Prof Aafiya) via his email, prof.aafiyahealingspells@gmail.com .
ReplyDeleteI now believe in super-naturalistic healing very much because my own case has proved to me that there is nothing impossible. Once again thanks for this great article.
