Hearing Loss

This article is about Hearing Loss...actually i want to post this article because now my housemate got problem with her ear..mybe this will help me to find some info at the same time will share to you all ladies out there...Happy Reading..

Hearing loss is the total or partial inability to hear sound in one or both ears.


Minor decreases in hearing are common after age 20.
Hearing problems usually come on gradually, and rarely end in complete deafness.
There are many causes of hearing loss. Hearing loss can be divided into two main categories:
  • Conductive hearing loss (CHL) occurs because of a mechanical problem in the outer or middle ear. The three tiny bones of the ear (ossicles) may not conduct sound properly, or the eardrum may not vibrate in response to sound. Fluid in the middle ear can cause this type of hearing loss.
  • Sensorineural hearing loss (SNHL) results when there is a problem with the inner ear. It most often occurs when the tiny hair cells (nerve endings) that transmit sound through the ear are injured, diseased, do not function properly, or have prematurely died. This type of hearing loss is sometimes called "nerve damage," although this is not accurate.
CHL is often reversible. SNHL is not. People who have both forms of hearing loss are said to have mixed hearing loss.

Common Causes

Ear infections are the most common cause of temporary hearing loss in children. Fluid may stay in the ear after an ear infection. The fluid can cause significant hearing problems in children. Any fluid that remains for longer than 8 - 12 weeks is cause for concern.
Causes that are present at birth (congenital):
  • Birth defects that cause changes in the ear structures
  • Genetic syndromes (more than 400 are known)
  • Infections the mother passes to her baby in the womb (such as toxoplasmosis, rubella, or herpes)
Traumatic causes:
  • Acoustic trauma such as from explosions, fireworks, gunfire, rock concerts, and earphones
  • Age-related hearing loss (presbycusis)
  • Barotrauma (differences in pressure, most often from scuba diving)
  • Skull fracture (temporal bone)
  • Traumatic perforation of the eardrum
  • Working around loud noises on a day-to-day basis (can damage the cells responsible for hearing)

Home Care

You can often flush wax buildup out of the ear (gently) with ear syringes (available in drug stores) and warm water. Wax softeners (like Cerumenex) may be needed if the wax is hard and stuck in the ear.
Take care when removing foreign bodies. Unless it is easy to get to, have your health care provider remove the object. Don't use sharp instruments to remove foreign objects.
See your health care provider for any other hearing loss.

Call your health care provider if

Call your health care provider if:
  • Hearing problems interfere with your lifestyle
  • Hearing problems do not go away or become worse
  • The hearing is worse in one ear than the other
  • You have sudden, severe hearing loss or ringing in the ears (tinnitus)
  • You have other symptoms, such as ear pain, along with hearing problems
  • You have new headaches, weakness, or numbness anywhere on your body

What to expect at your health care provider's office

The health care provider will take your medical history and do a physical examination.
Medical history questions may include:
  • Is the hearing loss in both ears or one ear?
  • Is the hearing loss mild or severe?
  • Is all of the hearing lost (inability to hear any sound)?
  • Is there decreased hearing acuity (do words sound garbled)?
  • Is there decreased ability to understand speech?
  • Is there decreased ability to locate the source of a sound?
  • How long has the hearing loss been present?
  • Did it occur before age 30?
  • What other symptoms are present?
  • Is there tinnitus (ringing or other sounds)?
  • Is there ear pain?
  • Is there dizziness or vertigo?
  • Do you have other family members with hearing loss?
The physical examination will include a detailed examination of the ears.
Diagnostic tests that may be performed include:
A hearing aid or cochlear implant may be provided to improve hearing.
