• Open Dialogue: Encourage questions and address any doubts they may have, ensuring they feel heard and understood.

What differential diagnoses would you consider with Barbara’s presentation, and what are the diagnoses not to miss? What investigations would you do to help confirm your most likely diagnosis?

Differential Diagnoses:

1. Presbycusis: Age-related hearing loss, typically sensorineural, affecting both ears gradually.
2. Cerumen Impaction: Build-up of earwax causing conductive hearing loss.
3. Otitis Media with Effusion: Fluid accumulation in the middle ear without signs of acute infection.
4. Otosclerosis: Abnormal bone growth in the middle ear leading to conductive hearing loss.
5. Acoustic Neuroma (Vestibular Schwannoma): A benign tumor on the vestibulocochlear nerve, causing unilateral hearing loss, tinnitus, and balance issues.
6. Meniere’s Disease: Inner ear disorder causing episodic vertigo, tinnitus, fluctuating hearing loss, and a feeling of fullness in the ear.
7. Sudden Sensorineural Hearing Loss (SSNHL): Rapid loss of hearing in one or both ears over a short period, often idiopathic but can be due to infections or vascular causes.
8. Chronic Otitis Media: Long-standing ear infection with possible perforation of the tympanic membrane.
9. Medication Ototoxicity: Hearing loss resulting from the use of ototoxic medications (e.g., certain antibiotics, chemotherapy agents).
10. Cognitive Impairment: Hearing difficulties perceived as communication issues related to cognitive decline or dementia.

Diagnoses Not to Miss:

1. Acoustic Neuroma: Can lead to serious complications if left untreated.
2. Sudden Sensorineural Hearing Loss (SSNHL): Requires urgent treatment to improve the chances of recovery.
3. Chronic Otitis Media with Cholesteatoma: Can cause significant complications, including hearing loss and intracranial infections.

Investigations to Confirm Most Likely Diagnosis (Presbycusis and others):

Basic Investigations:

1. Otoscopy: Visual examination of the ear canal and tympanic membrane to rule out cerumen impaction, infection, or other visible abnormalities.
2. Pure Tone Audiometry (PTA): Measures hearing thresholds across various frequencies to determine the type and degree of hearing loss.
3. Tympanometry: Assesses middle ear function by measuring the movement of the tympanic membrane.
4. Speech Audiometry: Evaluates the ability to hear and understand speech, providing insight into functional hearing capabilities.

Advanced Investigations (if indicated):

1. Magnetic Resonance Imaging (MRI): Used if an acoustic neuroma or other retrocochlear pathology is suspected.
2. Computed Tomography (CT) Scan: May be used to assess bony structures of the ear in cases of suspected otosclerosis or chronic otitis media with cholesteatoma.

Differential Diagnoses for a 25-Year-Old Pregnant Woman with Hearing Loss

Differential Diagnoses:

1. Infections: CMV or syphilis can affect hearing.
2. Eustachian Tube Dysfunction: Hormonal changes during pregnancy can lead to congestion and Eustachian tube dysfunction, causing conductive hearing loss.
3. Otitis Media with Effusion: Fluid accumulation in the middle ear due to changes in pressure or infection.
4. Sudden Sensorineural Hearing Loss (SSNHL): Rapid onset of sensorineural hearing loss, often idiopathic but can be triggered by viral infections or vascular events.
5. Otosclerosis: Pregnancy can exacerbate this condition, which involves abnormal bone growth in the middle ear leading to conductive hearing loss.
6. Cerumen Impaction: Accumulation of earwax causing conductive hearing loss.
7. Meniere’s Disease: Inner ear disorder causing episodic vertigo, tinnitus, fluctuating hearing loss, and a feeling of fullness in the ear.
8. Pregnancy-Related Hormonal Changes: Hormonal changes during pregnancy can lead to temporary hearing loss or changes in hearing acuity.
9. Medication Ototoxicity: Exposure to ototoxic medications during pregnancy (though less common, it must be considered).
10. Acoustic Neuroma: Although rare, a benign tumor on the vestibulocochlear nerve can cause unilateral hearing loss, tinnitus, and balance issues.

Diagnoses Not to Miss:

1. Sudden Sensorineural Hearing Loss (SSNHL): Requires urgent evaluation and treatment.
2. Acoustic Neuroma: Needs to be ruled out if there are unilateral symptoms or associated neurological signs.
3. Meniere’s Disease: Can have significant impacts on quality of life and requires proper management.

Investigations to Considerations During Pregnancy:

1. Blood Tests: To check for infections such as CMV or syphilis that can affect hearing.
2. MRI (without gadolinium): If an acoustic neuroma or other retrocochlear pathology is suspected. Avoid contrast agents due to pregnancy.

What is your approach to managing a six-year-old child with a one-day history of a sore ear secondary to an upper respiratory tract infection? How can you rationalise your prescribing of oral antibiotics in children?

Approach:

1. History and Examination:
   • Detailed history including onset, duration, and associated symptoms.
   • Otoscopic examination to check for signs of otitis media or external ear infection.
2. Diagnosis:
   • Acute Otitis Media (AOM) is likely if the tympanic membrane is bulging and inflamed.
   • Otitis Externa if there is ear canal inflammation.
3. Management:
   • Analgesia: Paracetamol or ibuprofen for pain relief.
   • Observation: Many cases of AOM resolve spontaneously within 48-72 hours.
   • Antibiotics: Consider prescribing if symptoms are severe, there is a high fever, bilateral AOM in children under 2 years, or if symptoms persist/worsen after 48 hours.
4. Rationalizing Antibiotics:
   • Avoid unnecessary antibiotics to prevent resistance.
   • Educate parents on the natural course of AOM and the role of antibiotics.

Persistent Otitis Media or High-Risk Populations:

1. Persistent Otitis Media:
   • Review: Reassess the child and consider extended antibiotic therapy.
   • ENT Referral: For persistent effusion, recurrent infections, or hearing loss.
2. High-Risk Populations:
   • Immediate Antibiotics: Consider for Aboriginal and Torres Strait Islander children due to higher rates of complications.
   • Follow-Up: Ensure close monitoring and follow-up.

Would your management change for a child presenting with persistent otitis media or for a child from a vulnerable or high-risk population, for example, Aboriginal and Torres Strait Islander?

Managing Barbara with Persistent Ear Discharge

Approach:

1. History and Examination:
   • Detailed history including duration, characteristics of discharge, associated symptoms.
   • Otoscopic examination to check for tympanic membrane perforation or cholesteatoma.
2. Diagnosis:
   • Chronic Otitis Media: Likely if there is persistent discharge with a perforated tympanic membrane.
   • Malignant Otitis Externa: Consider in immunocompromised patients or diabetics.
3. Management:
   • Topical Antibiotics: For chronic otitis media with perforation.
   • Systemic Antibiotics: If severe infection or signs of systemic involvement.
   • ENT Referral: For persistent or recurrent cases, or suspicion of cholesteatoma.

For a Child:

• Similar approach with emphasis on early referral to an ENT specialist if complications are suspected or there is no response to treatment.

What would your approach be if Barbara had a persistent ear discharge? What other serious conditions should not be missed? What if she were a child? Would your approach to management change?

Serious Conditions Not to Miss

In Adults:

• Cholesteatoma: Aggressive growth of squamous epithelium in the middle ear.
• Malignant Otitis Externa: Severe infection often seen in diabetics and immunocompromised patients.

In Children:

• Mastoiditis: Extension of middle ear infection into the mastoid bone.
• Cholesteatoma: Needs early identification and treatment to prevent complications.

Referral for a Perforated Ear Drum

When to Refer:

• Persistent Perforation: Lasting more than 3 months.
• Recurrent Infections: Despite adequate medical treatment.
• Hearing Loss: Significant impact on hearing.
• Suspicion of Cholesteatoma: Based on otoscopic findings.

Summary of Complications in Otitis Media and Related Conditions

1) Tympanic Membrane (TM) Perforation:

• Acute Otitis Media (AOM) with TM Perforation:
  • Common and results in otorrhoea (ear discharge) and often pain relief.
  • Differentiation from Otitis Externa:
    • Otorrhoea with TM perforation typically follows AOM symptoms like fever and ear pain, while otitis externa presents with pain upon touching the outer ear and a normal TM on otoscopy.

2) Acute Mastoiditis (AM):

• Characteristics:
  • Most common suppurative complication of AOM, though rare.
  • Can lead to intracranial complications.
• Diagnosis:
  • Based on post-auricular inflammatory signs (erythema, oedema, tenderness, or fluctuance).
  • Protruding auricle and external auditory canal oedema with AOM signs.
• Management:
  • Requires prompt treatment with IV antibiotics (e.g., flucloxacillin plus a 3rd generation cephalosporin).
  • ENT consultation is necessary for potential surgical intervention.

3) Otitis Media with Effusion (OME):

• Definition:
  • Fluid in the middle ear without infection signs, leading to transient hearing impairment.
  • Not diagnostic of AOM; effusion can persist up to 12 weeks post-AOM.
• Management:
  • Antibiotics and ENT referral are not routinely required.
  • Most cases resolve spontaneously without affecting language, literacy, or cognitive development.
  • Persistent effusion beyond 3 months warrants a hearing assessment and potential ENT referral.

Other Complications:

• Suppurative Complications:
  • Intracranial spread of infection is rare.
• Facial Nerve Palsy:
  • Should be discussed with ENT.
• Long-term Non-Suppurative Complications:
  • Include TM atelectasis and cholesteatoma.

When do you refer a patient with a perforated ear drum?

Red flags

• Marginal perforations
• Attic perforations
• Chronically discharging or bleeding ear
• Perforation with significant clinical hearing loss

Key diagnoses

• Safe perforations — dry and central, away from the attic or the annulus margins. These will generally not progress to serious pathology.
• Unsafe perforations — attic, marginal and chronically discharging perforations. These may progress to serious pathology.

When to refer

• Attic or marginal perforation (especially if patient is symptomatic).
• Central perforation that is symptomatic (discharge or hearing loss).
• Retracted eardrum with squamous debris collecting.
• Retracted eardrum with symptomatic hearing loss.

Consultation and Transfer Guidelines:

• Local Paediatric Team Consultation:
  • For children who are systemically unwell, neonates, or those with acute mastoiditis or cochlear implants.
• Consider Transfer:
  • When care required exceeds local hospital capabilities.
• Emergency Advice and Transfers:
  • Contact Retrieval Services for paediatric or neonatal ICU transfers.

What if Barbara’s hearing loss was contributed to by wax in her ear? What do you need to consider when getting consent from Barbara for an ear syringe?

Managing Barbara’s Hearing Loss Due to Ear Wax

from – AFP VOL.44, NO.10, OCTOBER 2015

Indications for Treatment

• Cerumen (earwax) accumulation is normal and typically does not require treatment unless symptomatic.
• Impacted wax usually warrants removal if it obscures visualization of the tympanic membrane and causes symptoms such as conductive hearing loss, ear pain, itching, fullness, dizziness, tinnitus, or reflex cough.
• Up to one-third of cases may resolve within five days without treatment.
• Removal is often indicated for diagnostic purposes or to allow audiometry.

Treatment Options

• First-Line Treatment: Use cerumenolytics (eardrops such as docusate sodium) to soften wax and increase clearance likelihood. There is no significant difference between water-based or oil-based drops.
• Cotton Buds: Discourage use in the ear canal as they can push wax further in and cause damage. Cotton buds have a very limited role and should only be used on the outer ear.
• Hard Impaction/Ear Canal Disease: May require irrigation or manual removal under a microscope by a trained professional or ENT specialist. Pre-treatment with cerumenolytics can improve the success of subsequent irrigation.

Safe Ear Syringing

• Perform irrigation only after taking a full history, examining the ear, and explaining potential complications.
• Use appropriate equipment, such as a large syringe (20 mL) with warm, sterile water or saline to reduce infection risk.
• Direct the water jet towards the edge of the cerumen to help debris flow out. Stop immediately if the patient experiences pain or bleeding.
• After syringing, examine the ear canal and tympanic membrane, and document the procedure.

Contraindications for Ear Syringing

• Signs or symptoms of current otitis externa or otitis media.
• History of tympanic membrane perforation or ear surgery.
• Unilateral deafness: avoid syringing the only or better hearing ear.
• Uncooperative patients (e.g., children).
• History of recurrent otitis externa or tinnitus.
• Immunocompromised patients at increased risk of infection.

Side Effects and Complications of Syringing

• Possible damage to the ear canal or tympanic membrane, leading to severe but temporary side effects such as coughing, tinnitus, or vertigo.
• Risk of clinically significant complications like tympanic membrane perforation or external auditory canal (EAC) trauma.
• Predisposition to infections (otitis media and externa), especially if water is retained behind incompletely removed cerumen.
• Traumatic tympanic membrane perforations typically heal without treatment but may require ciprofloxacin-based topical drops for infection.

Other Mechanical Removal Options

• Microsuction: Safe, effective, and usually performed in ENT outpatient clinics. It avoids moisture exposure, reducing infection risk, though it may cause discomfort due to noise.
• Curettage: Often used alongside microsuction.

When to Refer to an ENT Specialist

• Pain or bleeding during syringing.
• Failure to remove cerumen after multiple attempts.
• Persistence of symptoms despite successful cerumen removal.
• Chronic cerumen impaction.
• Contraindications, such as perforated tympanic membrane or prior ear surgery.
• Cerumen impaction in the only or better hearing ear.
• Presence of abnormal tissue in the ear canal.
• Any other concerns regarding ear health.

Microsuction

Advantages:

• Safety: Generally considered safer as it avoids the introduction of moisture into the ear canal, thereby reducing the risk of infection, particularly otitis externa and otitis media.
• Precision: Allows for direct visualization and targeted removal of earwax under magnification, which minimizes the risk of trauma to the ear canal and tympanic membrane.
• Fewer Complications: Associated with a lower incidence of adverse effects such as perforation of the tympanic membrane and ear canal trauma.
• Suitability for High-Risk Patients: Preferred for patients with contraindications to irrigation, such as those with a history of ear surgery, perforated eardrum, or recurrent ear infections.

Disadvantages:

• Discomfort: Some patients may find the noise from the suction device uncomfortable or distressing.
• Availability: Often limited to ENT outpatient clinics or specialized ear care services, which may not be accessible in all settings.

Irrigation

Advantages:

• Effectiveness: Effective for removing soft and non-impacted earwax.
• Accessibility: Can be performed in primary care settings, making it more widely available than microsuction.
• Cost: Typically less expensive than microsuction due to the lower cost of equipment and broader availability of trained personnel.

Disadvantages:

• Risk of Infection: Introduction of water into the ear canal can increase the risk of otitis externa and otitis media, particularly if sterile water or saline is not used.
• Potential for Trauma: There is a higher risk of ear canal and tympanic membrane trauma, especially if performed improperly or if the patient has contraindications.
• Contraindications: Not suitable for patients with perforated eardrums, active ear infections, or a history of ear surgery.

Evidence Summary

Safety Profile:

1. Infection Risk:
   • Microsuction: Lower risk of infections as it avoids introducing moisture into the ear canal.
   • Irrigation: Higher risk of infections if sterile techniques are not used. Water left in the ear canal can predispose to otitis externa and otitis media.
2. Trauma and Complications:
   • Microsuction: Lower incidence of trauma to the ear canal and tympanic membrane. Allows for careful, controlled removal under direct vision.
   • Irrigation: Higher risk of causing tympanic membrane perforation and ear canal trauma, especially in patients with contraindications.
3. Patient Tolerance:
   • Microsuction: Better tolerated in terms of avoiding the discomfort associated with water in the ear, though some patients may be sensitive to the noise.
   • Irrigation: Generally well-tolerated but can cause discomfort, vertigo, and temporary hearing loss if water is not at body temperature or if too much pressure is used.

Management of earwax – NICE UK 2018 – Recommendations

1. Offer Earwax Removal: Provide earwax removal services in primary care or community ear care settings if the earwax is causing hearing loss, other symptoms, or needs to be removed for examination or ear canal impression.
2. Ear Irrigation Procedure:
   • Use pre-treatment wax softeners immediately before ear irrigation or for up to 5 days beforehand.
   • If irrigation is unsuccessful:
     • Repeat use of wax softeners, or
     • Instill water into the ear canal 15 minutes before repeating ear irrigation.
   • If the second irrigation attempt is unsuccessful, refer the person to a specialist ear care service or ENT service for removal.
   • Suggests that ear irrigation can be used if appropriate precautions are taken and contraindications are considered. Microsuction is preferred for patients at higher risk of complications or when irrigation is contraindicated.
3. Consider Alternative Methods: Use ear irrigation with an electronic irrigator, microsuction, or another method (e.g., manual removal with a probe) if the practitioner:
   • Has training and expertise in the method.
   • Is aware of any contraindications.
   • Has the correct equipment available.
4. Avoid Manual Ear Syringing: Do not offer manual ear syringing to remove earwax in adults.
5. Advice Against Self-Removal: Advise adults not to use small objects (e.g., cotton buds) to remove earwax or clean their ears, as this can damage the ear canal and eardrum, and push wax further into the ear.

What would your approach be for a five-year-old child who presents at the emergency department with a suspected foreign body in their ear?

General Advice:

• Build Rapport: Establish trust with the child and their parent to ensure the child is relaxed and cooperative.
• Consider Sedation: If the child is uncooperative, consider referring to ENT for sedation to maximize the chance of successful removal.

The Ear

Initial Steps:

• Positioning: Ensure the patient is comfortable and secure.
• Assessment: Determine if removal is appropriate. Refer to ENT for button batteries, sharp objects, tightly wedged foreign bodies, or unsuccessful attempts.
• Check Tympanic Membrane: If there is a perforation, avoid using liquids and proceed with caution.

Potential Methods for Removal:

1. Forceps Removal:
   • Use crocodile forceps for graspable objects.
   • Hide forceps from the patient’s view to reduce anxiety.
2. Irrigation:
   • Kill live insects first using alcohol, 2% lignocaine, or mineral oil.
   • Do not irrigate if there is a button battery, organic matter, or suspected tympanic membrane perforation.
   • Use warm water and aim at the side of the ear canal to dislodge the foreign body.
3. Modified Suction:
   • Use a cut 12Fr suction catheter or soft tubing from a butterfly needle for gentle suction.
   • Avoid using large yankauer suction catheters.
   • Set pressure at 100-140mmHg and warn the patient about the noise.
4. Glue (Risky Strategy):
   • Apply a small amount of wound glue on a syringe or Q-tip to adhere to the foreign body.
   • Use an ear speculum to guide the glue and avoid sticking the ear canal.
5. Magnets (Riskier Strategy):
   • Use a small magnet for magnetic foreign bodies, ensuring the magnet is appropriate and doesn’t drop into the ear.

Post-Removal:

• Ensure the entire foreign body is removed and check the other ear.
• Provide safety net advice and consider prophylactic antibiotic drops for abrasions.
• Refer to ENT if the foreign body cannot be removed or in cases of severe pain, suspected tympanic membrane rupture, or button battery entrapment.

The Nose

Initial Steps:

• Maintain a high index of suspicion for nasal foreign bodies in patients with unilateral purulent discharge, sinusitis, or recurrent epistaxis.

Potential Methods for Removal:

1. Mother’s Kiss:
   • Occlude the opposite nostril and have the parent blow into the child’s mouth.
   • Alternatively, use a bag valve mask with care to avoid excessive pressure.
2. Suction:
   • Apply gentle suction, starting from the inferior part of the nostril.
3. Curved Probe:
   • Use a Jobson Horne probe or a modified paperclip to scoop out the foreign body.

4. Foley Catheter:

• Insert a small Foley catheter past the foreign body, inflate the balloon with 1-3ml of air, and gently pull out the foreign body.

Referral to ENT:

• Immediate referral is needed for nasal foreign bodies if removal is unsuccessful due to the risk of aspiration during sleep.
