Some fundamental information on types of hearing loss are discussed first. Hearing loss relates to minor or excessive reduction on the level of hearing in a person. Hearing loss at varying degres of severity affects most of the population although it is more prevalent among the aged.
And if you are suffering from hearing loss, it is normal for you to want to look for solutions that would improve your situation as well as understand the causes of hearing loss. The causes of one’s hearing loss are actually divided into three regions: outer, middle and inner ear hearing problems.
The most common causes of hearing loss in the outer ear include excessive build up of ear wax and an infection in the ear’s auditory canal. While the treatment for outer ear hearing loss is simple and easily available, you have to be sure that you are going to get treated as soon as you can to prevent worsening the problem.
You experience hearing loss in your middle ear on the other hand when there is a stiffening of the delicate bones in the ear; inflammation in the ear; a buildup of fluid behind the eardrum and perforations in the eardrum. Middle ear hearing loss are typically treated by medication and surgery but in cases where both solutions are not possible, the use of hearing aids are recommended.
A lot of hearing problems happen in the inner ear with the most common cause being the body’s aging process while overexposure to loud noises being a close second followed by wrong use of medications and skill fracture.
These factors damage delicate hair cells in the inner ear that affects the transmission of signals to the auditory nerves within the ear. Because inner ear hearing loss are not generally addressed medically, the use of hearing implants or hearing aids are highly recommended.
So if you have hearing loss, what can you do? There are different options that you can look into when it comes to treating and rehabilitation from hearing loss and it all depends on the severity of the condition, the onset and the type of hearing loss that you are experiencing.
To start with, you need to undergo extensive assessment of your hearing so the doctors can determine what type of hearing loss you have and be able to discuss with you your treatment options. Although there are certain types of hearing loss that can be corrected using surgery or medication, the used of hearing aids are the most common solutions suggested by audiologists.
It is important to be sure that you are going to consult with a highly recommended audiologist to guarantee the quality of the services that they are going to provide you.
Do Those Regularly At High Altitudes Have More Of A Risk Of Suffering From Hearing Difficulties?
There are a lot of illnesses caused by being at altitude, in particular morbidity. These issues can affect anybody who stays at high altitude. There are various environmental factors present at high altitudes, including hypoxia, low atmospheric pressure and dry and cold weather. Those affected by altitude sickness generally find that hypoxia is the cause of this. Although it is known that hearing can also be affected, only very little research has been done into this. Let’s take a look at the otologic disorders that can be caused by high altitudes. All of the following information is underpinned by scientific research in 1548 subjects.
Out of the group, a single person presented with SHL (sudden hearing loss), but he did not experience either vertigo or tinnitus. He was at high altitude for four days before this happened. Tests demonstrated that the patient had experienced a sudden and dramatic drop in hearing thresholds. There was no damage visible to his ears, so he was told to rest and return to lower altitude. He did not show any improvement within the first 24 hours.
However, he then received HBO treatment, which eventually returned his hearing to normal. Out of the group, 15 presented with tinnitus, with the majority experiencing this on a bilateral level. In none of the patients were doctors able to find a reason for tinnitus being present. Conservative treatment was suggested, but some found it worsened and most noticed no difference.
As a consequence, patients were told that they should return to a lower altitude. This appeared to be highly effective, as the tinnitus was gone in almost all patients after just 10 days. Then, there were 7 people with vestibular disorders. Some of these patients had symptoms such as loss of balance or vertigo, but did not have any hearing loss.
Only half responded properly to the medical treatment offered. All were told to descend and had recovered fully in a week. Scientists also dealt with 18 people who had ear fullness or otalgia. Interestingly, each of these 18 people had been at high altitude for two days. None of these patients required any treatment and all felt the problem had resolved itself within two weeks.
Clearly, there is a link between high altitude and hearing loss. However, the amount of people that notice this effect is very small. However, due to the fact that all patients experienced a full recovery with time or by descending, there is still not a great deal of interest in the issue itself from the scientific community.
