Clinical Practice Guideline (Update): Earwax (Cerumen Impaction)

Area of Science:

• Otolaryngology
• Clinical Practice Guidelines
• Evidence-Based Medicine

Background:

• Cerumen impaction is a common condition defined as cerumen accumulation causing symptoms or preventing ear assessment.
• This guideline updates the 2008 version with new evidence and enhanced patient education components.
• It excludes specific ear conditions like dermatologic diseases, recurrent otitis externa, or post-surgical ear canals.

Purpose of the Study:

• To provide clinicians with evidence-based recommendations for identifying and managing cerumen impaction.
• To promote effective management strategies, including primary prevention and appropriate interventions.
• To address the needs of special populations and patients with modifying factors.

Main Methods:

• Systematic review of new evidence, including guidelines, systematic reviews, and randomized controlled trials.
• Development of a new algorithm for action statement relationships.
• Inclusion of consumer input and enhanced external review processes.

Main Results:

• Strong recommendation to treat or refer cerumen impaction when symptomatic or preventing assessment.
• Recommendations for proper ear hygiene, diagnosis, and assessment of modifying factors.
• Guidance on managing asymptomatic patients, those with hearing aids, and specific interventions like cerumenolytics, irrigation, and manual removal.
• Strong discouragement of ear candling.

Conclusions:

• Clinicians should treat symptomatic cerumen impaction or when it prevents ear assessment.
• Management should consider patient-specific factors and may involve cerumenolytics, irrigation, or manual removal.
• Referral to specialists is recommended for persistent cases or when initial management is unsuccessful.
