A conductive hearing loss is caused by any condition or disease that impedes the conveyance of sound in its mechanical form through the middle ear cavity to the inner ear. The reason for sensorineural hearing loss sometimes cannot be determined, it does not typically respond favorably to medical treatment, and it is typically described as an irreversible, permanent condition.
A mixed hearing loss can be thought of as a sensorineural hearing loss with a conductive component overlaying all or part of the audiometric range tested.
The conductive component may be amenable to medical treatment and reversal of the associated hearing loss, but the sensorineural component will most likely be permanent.
Figure: The outer ear consists of the auricle (unlabelled), the external auditory canal, and the lateral surface of the tympanic membrane (TM). Surprisingly perhaps, hypertension, obesity and diabetes is not associated with an increased risk of hearing loss(Shargorodsky et al 2010).
Dance clubs are often very loud and may be the main source of loud noise exposure outside of occupational exposure.
Musician's earplugs are available in ER-9, ER-15, and ER-25, according to ones need for noise reduction. Although diabetes per se is not associated with an overall greater risk of hearing loss (Shargorodsky et al 2010), hearing loss starts at an early age than the normal population.
Diabetics are also more prone to get external and middle ear infections, as well as more prone to develop cranial nerve palsies and stroke. As diabetes is commonly an autoimmune disorder, autoimmune inner ear disease may also contribute.
Sensorineural hearing loss may stem from the inner ear, the vestibulocochlear nerve, or the brain. Sensorineural hearing loss may occur due to a variety of factors that adversely affect the proper functioning of the ear. Sensorineural hearing loss is a form of permanent hearing loss that originates with problems in the inner ear, the vestibulocochlear nerve, or the brain. Also known as nerve deafness, sensorineural hearing loss may occur due to a variety of factors that adversely affect the proper functioning of the ear. Nerve deafness is usually considered an idiopathic condition, meaning there is no single, identifiable cause for its development.
Symptoms associated with sensorineural hearing loss are dependent on the age of the individual and the extent of the hearing loss upon diagnosis.
A diagnosis of nerve deafness may be confirmed with a complete medical history and an ear examination.
Treatment for sensorineural hearing loss may involve the use of a hearing device that fits just inside the ear. Cochlear implants are a prosthetic replacement for hearing and not considered a cure for hearing loss.
Complex in its composition, a cochlear implant is comprised of a microphone, speech processor, transmitter, stimulator, and receiver.
Following surgery, the individual may begin speech therapy and work closely with an audiologist and speech therapist.
According to US government statistics from the 60's (National Center for Health Statistics), only 8% of the entire US population has any difficulty with hearing at all. Examples of conditions that cause sensorineural hearing loss are noise and just living a long time. If you have a sensorineural hearing loss, your goal should be to find out why, if you can prevent it from getting worse, and if a hearing aid could help you in overcoming the impairments associated with hearing loss. If you have to have a hearing loss, it is best to have a conductive one, as these disorders are often fixable.
If you have a conductive hearing loss, your goal should be to find out why, if you can prevent it from getting worse, and if a hearing aid, surgery, or perhaps just wax removal might help you in overcoming the impairments associated with hearing loss.

Leskowitz MJ1, Caruana FF2, Siedlecki B2, Qian ZJ1, Spitzer JB2, Lalwani AK2.Asymmetric hearing loss is common and benign in patients aged 95 years and older. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. This type of hearing loss is called sensorineural hearing loss can be detected by individuals with sensorineural hearing loss.
In the vast majority of cases, sensorineural hearing loss is not treatable with or surgery. Sensorineural hearing loss is another type of hearing loss also known as SNHL or Sensor neural hearing loss.
Mixed hearing loss is the type of hearing loss that conductive hearing loss and sensorineural hearing loss is in combination. A conductive hearing loss can be the result of a blockage in the external ear canal or can be caused by any disorder that unfavorably effects the middle ear’s ability to transmit the mechanical energy to the stapes footplate. Generally, the cause of conductive hearing loss can be identified and treated resulting in a complete or partial improvement in hearing. The sensory component may be from damage to the organ of Corti, an inability of the hair cells to stimulate the nerves of hearing or a metabolic problem in the fluids of the inner ear.
Like conductive hearing loss, sensorineural hearing loss reduces the intensity of sound, but it might also introduce an element of distortion into what is heard resulting in sounds being unclear even when they are loud enough.
So, in addition to some irreversible hearing loss caused by an inner ear or auditory nerve disorder, there is also a dysfunction of the middle ear mechanism that makes the hearing worse than the sensorineural loss alone. Hearing aids can be beneficial for individuals with a mixed hearing loss, but caution must be exercised by the hearing care professional if the conductive component is due to an active ear infection. Sounds waves may travel through the ear but this nerve pathway is unable to send electrical impulses to the brain.
Persons with cochlear deficits fail OAE testing, while persons with 8th nerve deficits fail ABR testing.
The middle ear includes the medial surface of the eardrum, the ossicular chain, the eustachian tube, and the tympanic segment of the facial nerve. Postmeningitic hearing loss can be due to lesions of the cochlea, brainstem and higher auditory pathways, but usually is related to suppurative labyrinthitis (cochlear). It is a subtype of sensorineural hearing loss, and because it is due to cochlear damage, it is more specifically a cochlear problem. We have encountered several patients in our practice with transient hearing loss after going to a loud club.
These ear plugs require a visit to a clinic to get an impression made, so that they are specific for the ear being fitted.
The effects of type I diabetes mellitus on the cochlear structure and vasculature in human temporal bones. A long-term study on hearing status in patients with nasopharyngeal carcinoma after radiotherapy. Unsuccessful cochlear implantation in two patients with superficial siderosis of the central nervous system. Furthermore, only 3% of the population had difficulty hearing anything other than faint speech. Adults with hearing loss are more likely to be unemployed and earn less wages (Jung and Bhattacharyya, 2012). If we do the math, 90% of 8% of the population with a hearing loss works out to about 7% of the population. If we do the math again, as only 8% of the population has a hearing loss at all, and 90% of them are sensorineural, this means that only 0.8% of the population has a conductive hearing loss. Central hearing loss generally isn't helped to a great extent by medication or surgery, but preventing progression is important.
Sudden hearing loss as well as Congenital hearing loss may be due to sensorineural, conductive or central mechanisms. Association of hearing loss with decreased employment and income among adults in the United States .Ann Otol Rhinol Laryngol. Hearing Loss ; Types of Hearing Aids ; Benefits and Safety Issues What are the different types of hearing loss? The treatment for sensorineural hearing loss is often the use of hearing aids or cochlear implants. People have gone from wearing speaker boxes connected to a tube in the ear to almost Types and causes of hearing loss Types and causes of hearing loss are varied.

A bone-anchored hearing aid Mild to severe sensorineural hearing loss can often be helped with hearing aids or a middle ear implant. With this type of hearing loss, words Hearing loss has many causes, but excessive noise is the most common cause of hearing loss.
Following the completion of medical treatment for causes of the conductive hearing loss, hearing aids are effective in correcting the remaining hearing loss. The neural or retrocochlear component can be the result of severe damage to the organ of Corti that causes the nerves of hearing to degenerate or it can be an inability of the hearing nerves themselves to convey neuro chemical information through the central auditory pathways. Once any medically treatable conditions have been ruled out, individuals with a sensorineural hearing loss can be fit with hearing aids to give them access to speech and other important sounds. The inner ear includes the auditory-vestibular nerve, the cochlea and the vestibular system (semicircular canals). The piccolo generates sound levels up to 112db…roughly equivalent to a jackhammer at 30 feet.
Pathological studies suggest that it is due to microangiopathic involvement of inner ear blood vessels and subsequent stria vascularis atrophy and hair cell loss (Fukushima et al, 2004).
In US data between 1988 and 2006, mild or worse unilateral hearing loss (25 db or worse), is reported in 1.8% of adolescents.
If you are older, statistics say that while many of your older associates may have the same problem, it will probably get worse, so you should prepare yourself and do your best to slow down the rate that it gets worse. Chicago – Surgically implanted hearing aids anchored to the skull bone appear to be a durable treatment option that noticeably improves hearing among children with Mild to severe sensorineural hearing loss can often be helped with hearing aids or a middle ear implant. Cochlear implants are often a solution for severe or profound 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.
In addit Sensorineural hearing loss, the most common type, usually cannot be treated medically or surgically.
It’s mostly permanent because sensorineural hearing loss’ is very hard to be cured by medicals or surgery. There was greater risk in individuals with work exposure to loud noises, lower socioeconomic background and in ethnic minorities. Other things that cause conductive hearing losses are fluid in the middle ear, and disorders of the small bones (ossicles) in the middle ear. Sensorineural hearing loss: TICA totally implantable system for possible with a conventional hearing aid. Sensorineural hearing loss (also known as nerve deafness) is where the inner ear or actual hearing nerve itself is damaged. It is important to understand that hearing aids do not “give you your Once any medically treatable conditions have been ruled out, the treatment for sensorineural hearing loss is amplification through hearing aids. Also it’s known that some drugs are making toxic effect and creating sensorineural hearing loss.
There are lots of researches why depression is causing hearing impairment and it’s known that depression in every age may cause hearing loss.
A sensorineural hearing loss occurs when the inner ear or hearing nerve is damaged or becomes dysfunctional. Living troubles on understanding what people say in standard sound is the most known symptom. Also listening TV on higher than normal volume continuously and depression based hearing loss are the main symptoms of hearing impartibility. Some deep head traumas may cause sensorineural hearing loss and also rarely but aging may cause it.
Advances in hearing aid technology and cochlear implants are helping to improve communication for people affected by hearing loss. You will be asked about other medical conditions and about what over-the-counter and prescription medications you take. You may be asked to cover one ear at a time while listening to sounds at different volumes. Tests using a tuning fork can check if there is damage to the parts of the middle ear and eardrum that vibrate.
However, the doctor will try to identify the cause of your hearing loss before treatment can begin.
