Information 1-3

  • Undertaken to identify, manage and prevent ear disease and hearing loss

Health check recommendations

  • All adults > 15 years of age if clinically indicated
  • All Aboriginal and Torres Strait Islander > 15 years of age annually

1. Procedure

  • Ask the questions and perform the corresponding procedure. See Table 1.
  • Provide brief intervention as required
  • Determine if the person requires a referral and place on a follow-up and recall register. See Flowchart 1.

Table 1. Questions and procedures for adult ears and hearing

Do you have any difficulty hearing?

  • If ‘yes’ perform otoscopy, tympanometry and audiometry. See Flowchart 1.
  • Do not do tympanometry if pain or discharge

Do you have any ear pain or discharge?

  1. Performing otoscopy 1–3
    • Otoscopy is the visual examination of the ear canal and eardrum. See Figure 1.
    • If there is pain or notable discharge from the ear(s) do not proceed. Refer to the Primary Clinical Care Manual
    • Observe the bone behind the ear (mastoid) and the area under the ear for infection, swelling or tenderness
    • Check the pinna for size, shape, colour or lesions
    • Observe the ear canal for:
      • discharge
      • redness/swelling
      • fungal infections
      • lumps or bony growths
      • foreign bodies
      • wax
      • fluid
    • Inspect the eardrum (tympanic membrane) for:
      • colour:
        • transparent and shiny is normal
        • dull or opaque represents fluid behind eardrum
      • cone of light (reflection):
        • right ear at 5 o’clock and left ear at 7 o’clock
        • reflections elsewhere indicates bulging
      • the handle of the malleus
      • perforations
      • abnormalities of the attic region e.g. perforation, mass, growth
    • Repeat procedure for the other ear

Hearing health check review and referral procedure

  1. Performing tympanometry 1–3
    • Tympanometry is a test of middle ear function and measures:
      • ear canal volume (ECV)
      • middle ear pressure (daPa)
      • middle ear compliance or movement
      • See Resource 1. for further tympanometry support
    • If a person has had recent surgery, pain or if there is a perforation or discharge from the ear(s) do not proceed. Refer to the Primary Clinical Care Manual
    • A “Leak” or “Blockage” error can occur for many reasons:
      • clogged probe tip
      • probe tip too large or small
      • head movements or swallowing
      • probe tip against the ear canal wall
      • debris, foreign body or wax in ear canal
    • To rectify try:
      • a different sized probe tip
      • cleaning probe tip
      • reposition the probe tip in the ear canal

Figure 2. Tympanometry traces 1–3

Type A Normal

  • A peak within the normative values box
  • Normal ear canal volume (ECV) = 0.3 to 1.6 cm3
  • Normal middle ear movement (compliance) = 0.2–1.5 cm3
  • Normal middle ear pressure = +50 to -100 daPa

Middle ear pressure chart - normal

Type B Fail

  • A flat line or no peak indicates no middle ear movement or pressure
  • It is important to observe the ear canal volume when interpreting Type B findings

Possible causes

  • Otitis media with effusion (middle ear fluid)
  • Eardrum perforation (hole) or grommet indicated by large ear canal volume
  • Ear canal blockage indicated by small ear canal volume
  • Wax

Tympanometry chart b

Type C Fail

  • A peak to the left of the normative values box
  • Normal ear canal volume
  • Normal middle ear movement
  • Negative middle ear pressure

Possible causes

  • Eustachian tube not working properly

  1. Performing audiometry 1–3
    • Audiometry measures the ability of the ear to:
      • detect the pitch of a sound as hertz (Hz)
      • detect the loudness of a sound as decibels (dB)
    • Place headphones on patient. Test one ear at a time
    • Set hertz (Hz) dial to 4000 Hz and decibels (dB) to 50 dB. Test
    • The person ‘fails’ if they do not indicate they hear a sound
    • If the person indicates they can hear the sound then reduce to 35 dB and repeat
    • If the person indicates they can hear the sound then reduce to 25 dB and repeat
    • Repeat these steps until the person no longer responds
    • Record the lowest perceived dB the person responds to twice
    • Repeat for the other ear
    • Repeat the procedure for both ears at 2000 Hz and 1000 Hz
    • To ‘pass’, the person needs to respond twice to 25 dB at 1000, 2000 and 4000 Hz

2. Results

  • All adults should have
    • clean ears, free of pain, discharge or infection
    • pass all tests and hear clearly

3. Brief intervention 1–3

  • Ear disease and hearing loss is high in Aboriginal and Torres Strait Islander adults, related to frequent childhood ear infections, contributing to poor education, unemployment and justice system contact
  • Provide preventative information:
    • hand and face washing
    • regular nose blowing
    • avoid cigarette/vape smoke
    • avoid loud noises (e.g. earbuds or headphones)
    • only swim in running water or swimming pools
    • maintain healthy Diet and nutrition
    • avoid putting anything in the ears (including cotton buds)
    • if concerned present to health centre

4. Referral

5. Follow-up

  • Review as per Flowchart 1.
  • Place the person on a recall register if required
  • Ensure all referrals are actioned
  • Provide the person with details for the next scheduled follow-up appointment
