Cerumen impaction is defined by the American Academy of Otolaryngology as an accumulation of cerumen in the external auditory canal (EAC) that causes symptoms, prevents necessary ear assessment, or both. The EAC functions to collect and amplify sound while protecting the middle and inner ear from infection, trauma, and foreign bodies. Cerumen forms a hydrophobic barrier, and the delicate skin of the EAC facilitates directional desquamation, promoting natural self-cleaning. While excessive cerumen is often asymptomatic, patients may present with hearing loss, ear fullness, pruritus, dizziness, tinnitus, or otalgia. Diagnosis relies on clinical assessment, and management strategies range from observation in asymptomatic cases to procedural removal, with ear irrigation being a common, controlled method for symptomatic individuals or those requiring clearance before topical therapy. Careful consideration of contraindications, including tympanic membrane perforation, acute otitis externa, or recent ear surgery, is essential to prevent complications such as canal laceration, vertigo, infection, or tympanic membrane injury. This activity enhances clinicians’ competence in evaluating and managing cerumen impaction using ear irrigation. Participants review relevant anatomy, indications, contraindications, procedural technique, and risk mitigation strategies. Emphasis is placed on patient safety, proper equipment use, and the prevention of complications. Clinicians gain practical skills for assessment, irrigation, and follow-up care while learning to collaborate effectively with interprofessional team members, including nursing, audiology, and primary care colleagues, to ensure coordinated, high-quality care and optimize patient outcomes. Objectives: Identify patients at increased risk for recurrent cerumen accumulation, such as those with dermatologic disorders, narrow canals, or hearing aids. Apply best practices for patient preparation and procedural techniques for safe and effective ear irrigation for cerumen impaction. Determine which cases of cerumen impaction require referral to an otolaryngologist rather than management with ear irrigation alone. Implement effective collaboration and communication among interprofessional team members to improve outcomes and treatment efficacy for patients with cerumen impaction.

Cerumen, commonly known as earwax, is a naturally occurring substance produced in the outer portion of the external auditory canal (EAC). The EAC contains pilosebaceous glands, ceruminous glands, hair follicles, and sebaceous glands. Modified sweat secreted by ceruminous glands exhibits bactericidal and fungicidal properties and contributes to lubrication and self-cleaning of the EAC. As dead skin cells are shed and migrate out of the canal, they combine with sebaceous secretions and ceruminous sweat to form cerumen, which consists primarily of dead keratinocytes.[1] Cerumen functions as a protective barrier that traps foreign particles. Pathologies of the EAC include sebaceous cysts, furuncles, and glandular tumors, although cerumen accumulation and impaction remain the most common clinical concern. The American Academy of Otolaryngology defines cerumen impaction as "an accumulation of cerumen associated with symptoms, preventing the necessary assessment of the ear, or both."[2] Although cerumen is typically expelled from the EAC spontaneously with jaw movement, this mechanism may fail in some patients, leading to impaction. The condition occurs more frequently when normal cerumen extrusion is impeded by hearing aids, persistent use of earplugs or earbuds, or attempts to clean the ears with cotton-tipped applicators. Common symptoms include ear fullness, otalgia, pruritus, dizziness, cough, and decreased hearing.[3][4] Prevalence estimates indicate that approximately 5% of healthy adults, 10% of children, 57% of older adults, and 33% of patients with intellectual disability experience cerumen impaction.[5][6][7]

Nonclinicians may perform irrigation, which carries both advantages and potential disadvantages. Ear irrigation may be performed alone or after pretreatment with a cerumenolytic agent, such as acetic acid, mineral oil, or hydrogen peroxide.[8] A comprehensive history and physical examination, including otoscopy, is essential to confirm an intact tympanic membrane, verify the absence of tympanostomy tubes, and identify anatomical abnormalities, including squamous debris or retraction pockets suggestive of cholesteatoma or prior ear surgery, before attempting irrigation. Referral to an otolaryngologist is recommended if contraindications are present or irrigation fails to remove the cerumen.

Mild, transient symptoms, such as vertigo, hearing loss, and tinnitus, may occur following ear irrigation. These manifestations are often related to the temperature of the water or solution rather than mechanical trauma. Severe discomfort, nausea, or vomiting is uncommon. Although complications from ear irrigation for cerumen removal are rare, they can include ear canal lacerations causing bleeding, discomfort, and increased risk of otitis externa; tympanic membrane perforation, which generally heals spontaneously; and middle ear traumatic injuries, such as disruption of the ossicular chain, potentially resulting in hearing loss. Referral to an otolaryngologist should be considered for patients with suspected complications.

Interprofessional collaboration is essential for patient-centered management of cerumen impaction. This collaborative approach enhances clinical outcomes, ensures patient safety, maximizes patient and family satisfaction, and optimizes team performance. Each team member, including physicians, nurses, advanced practice providers, audiologists, and pharmacists, contributes specialized expertise. Roles include cerumen removal when indicated, identification and management of ear infections, hearing aid fitting, trauma assessment, and addressing other otologic concerns. Healthcare professionals must possess the clinical skills and expertise necessary to accurately diagnose, evaluate, and treat cerumen impaction. Ear irrigation improves patient outcomes, reduces discomfort, and prevents complications, though it must be administered judiciously to suitable patients, with informed consent obtained from both patients and their families. Ethical considerations require careful assessment when selecting treatment for individuals presenting with hearing loss or related symptoms. Clearly defining each team member’s responsibilities ensures effective utilization of specialized skills to enhance patient care and outcomes. Coordinated care delivery reduces errors, minimizes complications and delays, and promotes patient safety, well-being, and satisfaction.
