Key Takeaways:
- ENT UK’s 2024 guidance recommends microsuction as the preferred technique for clinical ear wax removal
- For the first time, the guidance explicitly identifies equipment noise as a clinical risk factor, with traditional devices reaching up to 140 dB
- Clinicians must evaluate their equipment’s noise profile and consider upgrading to lower-noise devices
- The guidance sets new benchmarks for informed consent, clinical governance, and referral pathways to specialist ENT services
ENT UK 2024 Guidance on Ear Wax Removal
ENT UK — the professional body representing ear, nose and throat specialists across the United Kingdom — issued updated guidance on ear wax management in 2024. This guidance has significant implications for how clinicians approach ear wax removal.
Key Recommendations
1. Microsuction as Preferred Method
ENT UK recommends microsuction as the preferred technique for clinical ear wax removal, citing:
- Superior safety profile compared to irrigation and syringing
- Direct visualisation throughout the procedure
- Suitability for patients with complex ear conditions
- Effectiveness across all wax types
2. Noise as a Risk Factor
For the first time, the guidance explicitly identifies equipment noise as a clinical risk factor during microsuction. This acknowledgement reflects growing evidence that:
- Traditional devices generate noise levels up to 140 dB
- High noise exposure can cause or worsen tinnitus
- Noise contributes to patient anxiety and vertigo
- Clinicians have an obligation to minimise avoidable risks
3. Training Standards
The guidance reinforces the importance of:
- Proper training in microsuction technique
- Competency assessment for practitioners
- Understanding of ear anatomy and pathology
- Knowledge of when to refer to specialist ENT services
4. Patient Selection
Clinicians should assess each patient individually, considering:
- History of ear conditions or surgery
- Current symptoms and ear examination findings
- Presence of contraindications
- Patient preferences and anxiety levels
Recognised Risks of Microsuction (Verbatim from ENT UK 2024 Guidance)
The following risks are listed explicitly in the ENT UK 2024 guidance, with incidence estimates. These are reproduced verbatim from the document and represent the canonical clinical reference for what clinicians are expected to discuss with patients before the procedure.
Trauma to the ear canal skin (1 in 20). This will be associated with more severe pain than expected or bleeding from the ear canal. Both usually settle within a few seconds or minutes once microsuction is stopped.
Trauma to the ear drum (<1 in 10,000). This will be associated with more severe pain than expected and may result in bleeding, hearing loss, vertigo or tinnitus.
Ear canal infection as a sequelae to trauma (1 in 500). A secondary infection can develop after a traumatic microsuction.
Severe vertigo (1 in 200). This can very occasionally occur in patients that have a canal wall down mastoid cavity but may also result from trauma to the ear, especially trauma to the ear drum.
Temporary (1 in 100) or permanent tinnitus (1 in 5,000). It is unusual to experience tinnitus following uncomplicated microsuction but some patients who are particularly sensitive to noise may develop tinnitus. This is usually temporary and may be associated with a temporary threshold shift.
Temporary (1 in 1,000) or permanent conductive hearing loss (<1 in 10,000). This is rare but can result from further impaction of debris in the ear canal, from blood that has built up as a result of trauma, or from trauma to the ear drum or ossicular chain.
Temporary sensorineural hearing loss / temporary threshold shift (1 in 100). The intensity of the sound from microsuction can, in sensitive patients, result in a temporary threshold shift. This usually lasts a few minutes but can last a few hours.
Permanent sensorineural hearing loss / permanent threshold shift (<1 in 10,000). It is extremely rare to develop permanent sensorineural hearing loss as a result of microsuction but there are very sporadic reports in the literature of this resulting from the noise generated by microsuction.
Figures quoted are estimates based on clinical experience.
Consent (Verbatim)
“It is very important that the process, the likely experience and potential risks are fully discussed with the patient prior to proceeding with microsuction. It is recommended that patients are given the information leaflet that accompanies this document which summarises what to expect and what could happen as result of microsuction. The clinician should document that this discussion has taken place and that the patient has agreed to proceed.”
The full Montgomery-compliant approach to consent for microsuction — including how to document the discussion and how to handle patients with reduced capacity — is covered in our informed consent for microsuction article.
Implications for Practice
Equipment Selection
The noise guidance means clinicians should:
- Evaluate the noise profile of their current equipment
- Consider upgrading to lower-noise devices
- Document equipment specifications as part of clinical governance
Modern devices like Zephyr by Spoke Medical align with this guidance, operating at ≤75 dB compared to the 140 dB peaks of traditional equipment.
Informed Consent
Clinicians should inform patients about:
- The nature of the procedure
- Expected noise levels
- Potential risks including noise-related effects
- Alternative treatment options
Clinical Governance
Practices should:
- Review their microsuction protocols against the new guidance
- Ensure equipment meets current safety expectations
- Maintain training records for all practitioners
- Audit patient outcomes and complications
Referral Pathways
The guidance clarifies when patients should be referred to specialist ENT services:
- Suspected cholesteatoma
- Persistent perforation
- Foreign body in the ear canal
- Failed wax removal
- Unexpected findings during examination
Impact on Commissioning
The ENT UK guidance influences NHS commissioning decisions around ear wax removal services:
- Supports the case for microsuction over irrigation in commissioned services
- Provides a framework for quality standards in ear wax removal clinics
- Informs training requirements for practitioners offering the service
- Sets expectations for equipment standards
For Equipment Manufacturers
The guidance effectively creates a new benchmark for microsuction device manufacturers:
- Noise levels should be as low as technically achievable
- Devices should support fingertip pressure control
- Equipment should minimise procedural interruptions
- Design should prioritise patient comfort alongside clinical effectiveness
