Sudden sensorineural hearing loss is the most common type and is considered a medical emergency.
In Australia, patients with sudden hearing loss can be referred by a GP to an ear specialist such as Dr. Brett Leavers, who practices at multiple locations in Sydney and regional NSW.

|---|---|
| Viral infections | Herpes viruses, mumps, measles, meningitis, COVID-19 |
| Autoimmune diseases | Immune system attacks the inner ear |
| Vascular problems | Reduced blood flow, blood clots, vasculitis |

Flying and Sudden Hearing Loss: What You Should Know
Flying with ear problems can be uncomfortable but rarely causes sudden hearing loss.
How Flights Affect Your Ears
- Pressure changes during ascent and descent
- Eustachian tube equalizes pressure between middle ear and throat
- When the tube is blocked, pressure builds up
Ear Barotrauma vs. Sudden Hearing Loss
| Feature | Ear Barotrauma | Sudden Hearing Loss |
|---|---|---|
| Onset | During flight | Can occur anytime |
| Duration | Improves after landing | Persists, does not improve |
| Ear involvement | Often both ears | Usually one ear |
| Recovery | Hours to 1-2 days | Days to weeks with treatment |
Tips for Flying with Ear Concerns
- Do not fly with an active ear infection
- Use a decongestant spray before descent (consult pharmacist first)
- Chew gum or yawn during landing
- Stay hydrated throughout the flight
If hearing does not return to normal within 24 hours after landing, see a doctor.
Diagnostic Process: What Tests to Expect
If a GP refers you to an ear specialist for sudden hearing loss, several tests may be performed.
Common Diagnostic Tests
| Test | What It Does | Time Required |
|---|---|---|
| Pure-tone audiometry | Measures hearing at different frequencies and volumes | 20-30 minutes |
| Tympanometry | Measures eardrum movement; checks for fluid | 5-10 minutes |
| MRI | Rules out acoustic neuroma or other tumors | 30-60 minutes |
| Blood tests | Checks for autoimmune markers, infections | 5 minutes |
What Happens During an Ear Consultation
| Step | What Happens |
|---|---|
| 1 | GP referral and medical history reviewed |
| 2 | Ear examination using an otoscope |
| 3 | Hearing assessment (or referral to audiologist) |
| 4 | Diagnosis explained |
| 5 | Treatment or surgical options discussed |
What to bring: GP referral, ID, medication list, symptom summary (when hearing loss started, how quickly it occurred, associated symptoms).
Dr. Brett Leavers is an ear specialist who performs these consultations at multiple locations across Sydney and regional NSW.
Treatment Options: What Works
Treatment depends on the underlying cause and how quickly you seek care.
First-Line Treatment
| Treatment | Details | Effectiveness |
|---|---|---|
| Oral corticosteroids (prednisone) | High doses for 7-14 days | Most effective within 48-72 hours |
| Intratympanic steroid injections | Steroids injected directly into middle ear | Used when oral steroids ineffective |
Other Treatments
| Treatment | Indication |
|---|---|
| Antiviral medications | If viral cause is suspected |
| Immunosuppressive drugs | For autoimmune causes |
| Hearing aids | For permanent hearing loss |
| Cochlear implants | For profound hearing loss |
| Vestibular rehabilitation | For balance issues |
Recovery Expectations
- Some patients recover fully
- Others recover partial hearing
- Some have no improvement despite treatment
- Tinnitus may persist even with hearing recovery
An ear specialist like Dr. Brett Leavers can help determine which treatment is right for you.
