Hearing Loss/Deafness Treatment/Surgery

Hearing Loss

There are many different causes of Hearing Loss/Ear discharging. The most common type of discharging from the ear is earwax, which keeps the ear.

Other types of discharge include blood, clear fluid, and pus. These may signal a ruptured eardrum or ear infection.

Diagnosis

AUDIOMETRY TEST

An audiometry exam tests your ability to hear sounds. Sounds vary, based on their loudness (intensity) and the speed of sound wave vibrations (tone).

Hearing occurs when sound waves stimulate the nerves of the inner ear. The sound then travels along nerve pathways to the brain.

Sound waves can travel to the inner ear through the ear canal, eardrum, and bones of the middle ear (air conduction). They can also pass through the bones around and behind the ear (bone conduction).

The INTENSITY of sound is measured in decibels (dB):

  • A whisper is about 20 dB.
  • Loud music (some concerts) is around 80 to 120 dB.
  • A jet engine is about 140 to 180 dB.

What does a hearing test show?

Pure tone audiometry charts the hearing level of different tone frequencies in both ears. On an audiogram chart, red O's indicate the right ear's results and blue X's the left ear's results

HEARING LOSS IS OFTEN DESCRIBED AS FOLLOWS:

  • Normal = Less than 25 dB HL
  • Mild = 25 - 40 dB HL
  • Moderate = 41-65 dB HL
  • Severe = 66-90 db HL
  • Profound = More than 90 dB HL

Impedance /Tympanometry Test

Tympanometry is an examination used to test the condition of the middle ear and mobility of the eardrum (tympanic membrane) and the conduction bones by creating variations of air pressure in the ear canal.

Tympanometry is an objective test of middle-ear function. It is not a hearing test, but rather a measure of energy transmission through the middle ear. The test should not be used to assess the sensitivity of hearing and the results of this test should always be viewed in conjunction with pure tone audiometry.

Tympanometry is a valuable component of the audiometric evaluation. In evaluating hearing loss, Tympanometry permits a distinction between sensorineural and conductive hearing loss, when evaluation is not apparent via Weber and Rinne testing. Furthermore, in a primary care setting, Tympanometry can be helpful in making the diagnosis of otitis media by demonstrating the presence of a middle ear effusion.
