Treatment of Blocked Ears in the Elderly
Clinicians should treat cerumen impaction when identified in elderly patients, as removal improves hearing and quality of life, with the elderly being particularly at risk and often unaware of their impairment. 1
Why Treatment is Critical in the Elderly
The elderly population faces unique challenges with cerumen impaction:
- 35% of hospitalized patients over age 65 have cerumen impaction blocking visualization of the tympanic membrane, yet the vast majority are unaware of their hearing deficits and rate their hearing as "good" or "fair" 1
- Hearing improvement occurs at multiple frequencies after wax removal, with studies showing resolution of hearing loss in patients who had been unaware of their deficits 1
- Cognitive performance improves when cerumen is removed in elderly subjects, as demonstrated by improved scores on deductive reasoning tests 1
- Symptoms of ear pressure, fullness, and irritation resolve after treatment 1
Treatment Algorithm
Step 1: Initial Assessment - Rule Out Contraindications
Before selecting a treatment method, assess for:
- History of tympanic membrane perforation, ear surgery, tympanostomy tubes, intratympanic injections, or barotrauma - if present, avoid irrigation and use mechanical removal instead 1
- Current otitis externa or ear pain - if present, avoid irrigation as pain suggests infection or other pathology requiring evaluation before wax removal 1
- Hearing aid use - examine these patients routinely during healthcare encounters as they have higher impaction rates 1
Step 2: First-Line Treatment - Cerumenolytic Drops
- Apply cerumenolytic drops for 3-5 days before considering other interventions 2
- All cerumenolytic types are equally effective - no specific agent has proven superiority over others, including plain saline or water 2, 3, 4
- Water-based agents are preferred due to lower risk of local skin reactions compared to oil-based products 2
FDA-approved dosing for adults over 12 years:
- Tilt head sideways and place 5-10 drops into ear 5, 6
- Keep drops in ear for several minutes by keeping head tilted or placing cotton in the ear 5, 6
- Use twice daily for up to 4 days 5, 6
Step 3: Second-Line Treatment - Irrigation
If cerumenolytics alone fail after 3-5 days:
- Use body-temperature water to avoid caloric effects that cause dizziness 2
- Direct the irrigation stream at the canal wall, NOT at the tympanic membrane 2
- Irrigation should only follow adequate cerumenolytic pretreatment - attempting irrigation without pretreatment increases failure rates and complication risk 2
- Studies show 62-75% symptom improvement after irrigation in patients presenting with blocked ears or hearing difficulty 1
Step 4: Third-Line Treatment - Manual Removal
Reserved for cases where cerumenolytics and irrigation have failed:
- Manual removal should be performed by a skilled healthcare provider with specialized equipment 2
- This is the preferred technique when eardrum perforation is suspected 1
Critical Interventions to AVOID
- Never use cotton-tipped swabs - they push wax deeper and can cause canal laceration, tympanic membrane perforation, or ossicular dislocation 2
- Never use ear candling - no evidence of efficacy and can cause burns, ear canal occlusion, and tympanic membrane perforation 2
Special Considerations for Elderly Patients
- Institutionalized elderly have higher cerumen impaction rates and require regular screening 1
- Cognitively impaired elderly may be unable to express symptoms - clinicians should proactively examine and treat impaction as hearing loss can further impair cognitive function 1
- Directed history and ear examination are warranted in older patients to identify impaction, as they are often unaware of the problem 1
Prevention for High-Risk Elderly
- Regular ear care every 6-12 months may prevent recurrence in those with history of impaction 1
- Weekly prophylactic topical emollient preparation reduced recurrence from 61% to 23% in one study, though patient adherence was challenging 1
- Hearing aid users require regular ear canal checks to prevent recurrence 2
Evidence Quality Note
The strongest recommendation comes from the 2017 American Academy of Otolaryngology-Head and Neck Surgery guideline (Grade B evidence from RCTs), which provides a strong recommendation for treating cerumen impaction due to preponderance of benefit over harm 1. The evidence consistently shows improved hearing and symptom relief compared with no treatment, with potential complications being rare and mild 1.
