Cerumen impaction and otalgia
Cerumen impaction and ear pain: the AU general practice approach
Ear pain (otalgia) is common in Australian general practice; causes are primary otologic — cerumen impaction, otitis externa, acute otitis media, herpes zoster oticus — or referred from jaw, teeth, throat.
Cerumen: soften with olive oil 3–7 days then irrigate; micro-suction if perforation suspected. Otitis externa: aural toilet, antibiotic-steroid drops. Most childhood AOM resolves without antibiotics; eTG exceptions: ATSI children, under 6 months, bilateral disease under 2, perforation, severe illness.
Red flags: postauricular swelling (mastoiditis), ear pain with facial palsy and vesicles (Ramsay Hunt), persistent unilateral otalgia in an adult over 50 — each requires urgent referral.
Ear pain and wax-related symptoms are among the most frequent presentations in Australian general practice. Otalgia — ear pain — accounts for approximately 2–3% of GP consultations, with a significant seasonal peak in summer related to otitis externa in swimmers, and a steady year-round burden from acute otitis media predominantly in young children. The challenge in managing otalgia is the broad differential: primary otologic causes and referred pain from multiple head and neck structures share the same symptom profile, and the consequences of missing a red-flag diagnosis are significant.
eTG complete provides the primary AU guideline reference for management across all otic conditions. This article summarises the GP approach to cerumen impaction, otitis externa, acute otitis media, Ramsay Hunt syndrome, and referred otalgia, with specific attention to the ATSI ear health context.
A. Core clinical — the AU general-practice framework
Taking the history
A structured history narrows the differential substantially:
- Onset and tempo — acute (hours to days) versus chronic or recurrent
- Character of pain — sharp and lancinating (neuralgia), deep and throbbing (AOM), burning and itchy (OE), fullness without pain (cerumen, OME)
- Aggravating factors — pain worsened by chewing or yawning (TMJ, dental), by tragal pressure (OE), after swimming (OE), after flying (barotrauma)
- Discharge — clear (eczema, CSF leak), purulent (OE, AOM with perforation, CSOM), foul-smelling (cholesteatoma), bloody (trauma, granulation tissue)
- Hearing loss — conductive (cerumen, OME, cholesteatoma) versus sudden sensorineural (emergency)
- Associated symptoms — fever, tinnitus, vertigo, facial weakness, vesicles in or around the ear
- Relevant history — recent swimming, diving, air travel, cotton bud use, URTI, ATSI status, diabetes or immunosuppression, ototoxic medications (aminoglycosides, cisplatin, loop diuretics)
Yellow-flag screening in children: speech or language delay, school absences, parent or teacher concern about hearing — all raise the possibility of chronic middle ear effusion with conductive hearing loss.
Examination
Otoscopy is mandatory and should be performed bilaterally in every patient with otalgia:
- Technique — adult: pull pinna up and back; child under 3: pull pinna down and back; use appropriate-sized speculum
- Canal — swelling and erythema with debris (OE), impacted wax, foreign body
- Tympanic membrane — intact or perforated; bulging red (AOM); retracted or dull with fluid (OME); attic retraction pocket (cholesteatoma); vesicles on the membrane (bullous myringitis or Ramsay Hunt)
- Pinna and postauricular area — vesicles, postauricular erythema, and swelling with protruding pinna are mastoiditis until proven otherwise
Additional examination:
- Tragal tenderness — positive in OE
- Facial nerve assessment — ask patient to wrinkle forehead, close eyes tightly, show teeth, puff cheeks
- Tuning fork (512 Hz) — Rinne test (AC vs BC) and Weber test to classify hearing loss as conductive or sensorineural
- Oral cavity, teeth, TMJ, throat, and neck — assess for referred sources; palpate cervical lymph nodes
Investigations
- First-line: otoscopy; tuning fork tests; pure-tone audiometry for any persistent hearing complaint, paediatric hearing concern, or ATSI child
- Tympanometry: Type A (normal), Type B (flat — effusion or perforation), Type C (negative pressure — Eustachian dysfunction)
- Swabs: for recurrent or refractory OE, CSOM, immunocompromised patients
- Imaging: CT temporal bones for suspected mastoiditis, malignant OE, or cholesteatoma; MRI for Ramsay Hunt with persistent palsy
- ENT flexible nasendoscopy: adults with persistent referred otalgia beyond 4 weeks and a normal ear — mandatory to exclude head and neck malignancy
B. Condition-specific management — evidence and approach
Cerumen impaction
Cerumen impaction is symptomatic accumulation obstructing the external auditory canal, seen in approximately 5% of adults, up to 10% of children, and 30% of elderly and cognitively impaired individuals.
Cerumenolytics — used for 3–7 days before irrigation (AMH — otic preparations):
- Olive oil — effective, cheap, first-line; 2–3 drops twice daily
- Sodium bicarbonate 5% — dissolves cerumen matrix
- Docusate sodium (Waxsol) — commercial; softens wax
- Carbamide peroxide (Ear Clear) — commercial; gentle effervescence
Irrigation: performed with body-temperature water; syringe or electronic irrigator; the water should be directed along the superior canal wall, not directly at the membrane. Contraindications: suspected or known perforation, previous mastoid surgery, tympanostomy tube, only-hearing ear. If perforation cannot be excluded, micro-suction by an experienced clinician is preferred and safer.
Cotton buds should not be inserted into the ear canal — they disrupt the natural outward epithelial migration of cerumen and push wax towards the membrane.
Otitis externa
OE is diffuse inflammation of the external auditory canal, most commonly bacterial (Pseudomonas aeruginosa, Staphylococcus aureus), with a seasonal peak in summer and wet climates. Per eTG complete:
- Aural toilet — gentle dry mopping of debris; suction by ENT or trained clinician for severe swelling
- Topical antibiotic and steroid drops × 5–7 days:
- Sofradex (framycetin + gramicidin + dexamethasone)
- Locacorten-Vioform (clioquinol + flumetasone)
- Kenacomb otic (neomycin + gramicidin + nystatin + triamcinolone)
- Ciproxin HC (ciprofloxacin + hydrocortisone) — preferred when perforation is suspected (no aminoglycoside ototoxicity risk)
- Keep ear dry during treatment: cotton wool with vaseline when showering; no swimming
- Oral antibiotics: only for cellulitis extending beyond the canal, systemic illness, diabetes, or immunosuppression — dicloxacillin or flucloxacillin 500 mg four times daily
- Fungal OE (otomycosis): acetic acid 2% drops, clotrimazole 1%, or boric acid in alcohol; aural toilet is essential alongside antifungal agents
Malignant (necrotising) OE: a rare but life-threatening complication occurring in diabetic or immunocompromised patients. Features include pain disproportionate to examination, granulation tissue in the floor of the canal, and cranial nerve palsies. This is an emergency — immediate ED referral and IV antipseudomonal antibiotics.
Acute otitis media
Acute otitis media (AOM) — the most common bacterial infection in Australian children — peaks between 6 and 24 months of age. Approximately 80% of children have experienced at least one episode by age 3.
Analgesia first: paracetamol 15 mg/kg up to four times daily, or ibuprofen 10 mg/kg three times daily in hydrated children over 3 months.
Watchful waiting applies in well-appearing children older than 6 months with non-severe unilateral disease — most resolve spontaneously. The RCH Melbourne Clinical Practice Guideline and eTG complete align on antibiotic indications:
Antibiotics indicated when:
- Aboriginal or Torres Strait Islander children — always (see ATSI section below)
- Under 6 months
- Bilateral disease under 24 months
- Any perforation with discharge
- Severe illness — high fever, significant pain, systemically unwell
- Failure to improve at 48–72 hours of watchful waiting
- Immunocompromised
First-line antibiotic: amoxicillin 30 mg/kg (maximum 1 g) orally, three times daily × 5 days for non-severe; 10 days for severe, perforated, ATSI, or children under 2 years.
Treatment failure or recent antibiotic exposure: amoxicillin-clavulanate 22.5/3.2 mg/kg twice daily × 5–7 days.
Penicillin allergy: cefuroxime or cefaclor for non-severe allergy; azithromycin for documented severe allergy (noting increasing macrolide resistance).
Ramsay Hunt syndrome (herpes zoster oticus)
Ramsay Hunt syndrome is varicella-zoster virus reactivation in the geniculate ganglion, producing severe otalgia, vesicles in the external auditory canal or on the tongue and palate, and facial nerve palsy. It carries a worse prognosis for facial nerve recovery than Bell’s palsy. Per eTG complete:
- Aciclovir 800 mg orally 5 times daily × 7 days, or valaciclovir 1 g three times daily × 7 days, or famciclovir 500 mg three times daily × 7 days — start within 72 hours of onset
- Prednisolone 1 mg/kg/day (maximum 60 mg) × 5 days, then taper
- Eye care if eye closure is impaired — lubricating drops during the day, eye taping at night (corneal abrasion risk)
- Urgent ENT and neurology referral
C. ATSI ear health — the Australian context
Aboriginal and Torres Strait Islander children have globally among the highest rates of otitis media. In some remote communities, CSOM prevalence reaches 30–50% — a rate the WHO classifies as a public health emergency. The Menzies Healthy Skin and Ear Health Guideline provides the specific AU evidence base.
The standard watchful-waiting approach to AOM does not apply to ATSI children: treat always with antibiotics given the elevated risk of CSOM progression, hearing loss, and its sequelae for speech development and educational outcomes. Amoxicillin for 10 days is standard.
The ATSI Health Assessment (MBS item 715) mandates ear examination and hearing assessment as a core component. All ATSI children with AOM should have hearing assessed 6–12 weeks after the episode. Refer earlier for ENT and grommet consideration when recurrent AOM (≥3 episodes in 6 months or ≥4 in a year) or persistent OME with hearing loss is present.
Hearing Australia and the Hearing for Learning Initiative provide community-level support infrastructure.

Referral criteria
Routine ENT: recurrent AOM (≥3 in 6 months or ≥4 in a year), persistent OME with hearing loss ≥3 months, chronic OE, narrow canal impeding management.
Semi-urgent ENT (within 1–2 weeks): suspected cholesteatoma (attic retraction, foul discharge), CSOM, adult referred otalgia persisting more than 4 weeks with normal ear.
Emergency/urgent (same day): mastoiditis (postauricular swelling, pinna protruding), malignant OE (diabetic or immunocompromised with disproportionate pain and granulation tissue), Ramsay Hunt syndrome, sudden sensorineural hearing loss (corticosteroid window within 72 hours), deeply impacted foreign body, disc battery in ear canal.
HealthDirect and the Better Health Channel provide accessible consumer guidance on when to seek emergency care.
E. Special populations
Neonates and infants. AOM is common from 6 months of age. Antibiotic threshold is lower for children under 6 months due to risk of bacteraemic complications. Otoscopy requires appropriate technique (pinna down and back for under 3 years).
Elderly patients. Cerumen impaction is more prevalent with age, hearing aid use, narrow or hairy canals, and cognitive impairment. Irrigation can cause vertigo; micro-suction is often better tolerated. Hearing loss in older adults is independently associated with depression and cognitive decline — the Hearing Australia Hearing Services Program provides subsidised audiological assessment for eligible adults.
Immunocompromised and diabetic patients. Malignant OE is the most important condition to exclude — the cardinal features are pain disproportionate to examination, granulation tissue at the floor of the external auditory canal, and cranial nerve deficits.
Swimmers. Recurrent OE can be prevented by instilling a few drops of acetic acid 2% solution or a diluted alcohol solution immediately after swimming to restore canal acidity.
When to escalate
Emergency ED referral (same day): mastoiditis, malignant OE, Ramsay Hunt syndrome, sudden sensorineural hearing loss, deeply impacted disc battery, suspected intracranial complication.
Urgent ENT referral (within days): facial palsy of any cause, suspected cholesteatoma, suspected head and neck malignancy presenting as referred otalgia.
Routine ENT referral: recurrent AOM, persistent OME, chronic OE, hearing aid assessment, confirmed CSOM.
Safety-netting for patients and carers: “Return promptly if pain worsens after 48 hours, fever does not settle, swelling appears behind the ear, facial weakness develops, or you cannot move your face normally.”

Frequently asked questions
-
Is it safe to syringe someone's ear at home or in the clinic?
Ear irrigation is safe when performed correctly with body-temperature water and a softening agent applied first for 3–7 days. It is contraindicated when there is a suspected or known tympanic membrane perforation, a history of mastoid surgery, a tympanostomy tube in place, or when the ear being irrigated is the patient's only hearing ear. Irrigation through a perforation risks introducing infection and causing vertigo. If perforation cannot be excluded by otoscopy, micro-suction by an experienced clinician is the preferred technique. Cotton buds should never be inserted into the ear canal — they push wax deeper and can abrade the canal skin.
-
When do children with ear infections actually need antibiotics?
Most acute otitis media in children is viral and resolves without antibiotics. eTG complete recommends watchful waiting with analgesia for 48–72 hours in well-appearing children older than 6 months with non-severe unilateral disease. Antibiotics are indicated for: Aboriginal and Torres Strait Islander children (always, given high CSOM risk), children under 6 months, bilateral disease in children under 24 months, any child with tympanic membrane perforation and discharge, severe illness (high fever, significant pain, systemic unwell), and any child failing to improve at 48–72 hours. First-line is amoxicillin 30 mg/kg (maximum 1 g) three times daily for 5 days (10 days for severe, perforated, or ATSI presentations).
-
What is Ramsay Hunt syndrome and why does it matter?
Ramsay Hunt syndrome is varicella-zoster virus reactivation in the geniculate ganglion of the facial nerve, producing a triad of severe otalgia, vesicles in the ear canal or on the tongue and palate, and facial nerve palsy. It is more severe than Bell's palsy — facial recovery is worse. Management requires high-dose aciclovir (800 mg five times daily for 7 days) or valaciclovir, plus prednisolone (1 mg/kg/day for 5 days), started as soon as possible within 72 hours of onset. Urgent ENT or neurology referral is required. Eye care is essential if eye closure is impaired — lubricating drops, night taping. GPs who mistake Ramsay Hunt for Bell's palsy and omit antiviral therapy may be contributing to worse long-term facial outcomes.
-
Why is ear health so important for Aboriginal and Torres Strait Islander children?
Australia has globally among the highest rates of otitis media in Aboriginal and Torres Strait Islander children. Up to 90% of ATSI children in some communities experience at least one episode of otitis media by age 3, and chronic suppurative otitis media (CSOM) prevalence reaches 30–50% in remote communities — rates the WHO classifies as a public health emergency. Hearing loss from untreated middle ear disease impairs speech development, school readiness, and educational outcomes. The standard antibiotic watchful-waiting approach does not apply to ATSI children; treat always with antibiotics. Refer earlier for audiology, ENT input, and grommets when eligible. The ATSI Health Assessment (MBS item 715) mandates an ear and hearing check.
-
When should referred ear pain in an adult prompt urgent review?
Approximately half of all otalgia in adults is referred from structures outside the ear — the temporomandibular joint, teeth, oropharynx, larynx, or cervical spine. When a thorough examination reveals a completely normal ear, referred otalgia becomes the diagnosis by exclusion. In adults over 50, in smokers, in people with alcohol use disorder, or when pain persists beyond 4 weeks, oropharyngeal, hypopharyngeal, or laryngeal malignancy must be excluded. HPV-related oropharyngeal cancer is rising in Australian adults. These patients need urgent ENT referral for flexible nasendoscopy, not further antibiotics or watchful waiting.
