SCENARIO

David Thompson, a 62-year-old retired electrician, presents with gradual hearing loss and sensation of blocked ears over the past 6 months. He describes muffled hearing and occasional tinnitus but denies pain, dizziness, or discharge.

He wears hearing aids intermittently but finds them less effective recently. He has tried cotton buds, which provided temporary relief but may have worsened impaction.

His past medical history includes hypertension, and he takes ramipril and atorvastatin.

On otoscopic examination, bilateral impacted cerumen is noted, completely obscuring the tympanic membranes. Weber and Rinne tests suggest a conductive hearing loss.

David is concerned about hearing loss and seeks advice on safe and effective management.

THE COMPETENT CANDIDATE

The competent candidate should be able to:

Q1: How would you assess David’s condition and confirm the diagnosis?

David presents with gradual hearing loss, a sensation of blocked ears, and occasional tinnitus, which are consistent with impacted cerumen. A structured assessment includes history, examination, and differentiation from other causes of hearing loss.

1. History

  • Onset and progression – gradual vs sudden hearing loss
  • Laterality – bilateral vs unilateral
  • Associated symptoms – pain, discharge, dizziness, vertigo (suggesting other pathology)
  • Use of cotton buds or hearing aids – risk factors for impaction
  • Previous ear infections or ear procedures

2. Otoscopic Examination

  • Impacted wax obscuring the tympanic membrane (confirming diagnosis)
  • Signs of infection or perforation (red flags)

3. Hearing Assessment

  • Weber and Rinne tests
    • Conductive hearing loss (Weber lateralises to affected ear, Rinne negative)
    • Sensorineural loss (e.g., presbycusis) has a different pattern

A diagnosis of cerumen impaction is confirmed, and other causes of hearing loss are ruled out.


Q2: What are the management options for David’s impacted cerumen?

1. First-Line Treatment

  • Cerumenolytics (ear drops such as sodium bicarbonate, olive oil, or docusate sodium)
  • Softens wax over several days to facilitate natural expulsion or removal

2. Manual Removal

  • Curettage or microsuction
  • Preferred in patients with contraindications to irrigation

3. Ear Irrigation (Ear Syringing)

  • Indicated if cerumenolytics fail and there are no contraindications
  • Use body-temperature water to avoid vertigo
  • Monitor for discomfort or signs of infection

4. Follow-Up

  • Review in 1-2 weeks if symptoms persist
  • Assess hearing once wax is cleared

Q3: What are the contraindications for ear syringing, and when should an alternative approach be used?

1. Absolute Contraindications

  • Perforated tympanic membrane (or history of perforation)
  • Recurrent ear infections
  • Grommets in situ
  • Recent ear surgery

2. Relative Contraindications

  • Severe otitis externa
  • Diabetes (risk of infection)

3. Alternative Approaches

  • Microsuction or manual removal
  • Referral to ENT if complex or recurrent cases

Avoiding syringing in high-risk patients prevents complications like infection and perforation.


Q4: What preventive measures would you recommend to David to reduce recurrent cerumen impaction?

1. Safe Ear Hygiene Practices

  • Avoid cotton buds (pushes wax deeper)
  • Limit use of hearing aids during active wax build-up
  • Regular cerumenolytics if prone to impaction

2. Education on Natural Ear Cleaning

  • Wax naturally migrates out of the ear canal
  • Tilt head while showering to allow water drainage

3. Regular Monitoring

  • Routine ear checks for hearing aid users
  • Early intervention if symptoms recur

Preventive care reduces recurrence and maintains optimal hearing health.


Q5: When would you refer David to an ENT specialist?

1. Red Flags Requiring Urgent Referral

  • Unilateral hearing loss without clear cause
  • Persistent tinnitus or vertigo
  • Suspected tympanic membrane perforation or cholesteatoma

2. When Routine ENT Referral is Needed

  • Recurrent or impacted wax despite treatment
  • Patients with anatomical abnormalities (e.g., narrow ear canals)
  • Persistent conductive hearing loss after wax removal

Timely referral ensures appropriate specialist management for complex cases.


SUMMARY OF A COMPETENT ANSWER

  • Accurately diagnoses cerumen impaction based on history and examination
  • Considers alternative causes of hearing loss and performs appropriate assessments
  • Provides safe and effective treatment options, including cerumenolytics and irrigation
  • Recognises contraindications for ear syringing and recommends alternatives when needed
  • Offers preventive strategies to minimise recurrence
  • Identifies red flag symptoms that warrant ENT referral

PITFALLS

  • Failing to differentiate conductive from sensorineural hearing loss
  • Performing ear syringing in a contraindicated patient (e.g., perforation, infection)
  • Not educating on proper ear hygiene, leading to recurrent impaction
  • Ignoring red flags such as unilateral hearing loss or persistent tinnitus
  • Overlooking referral when specialist intervention is required
