Ear Conditions Flashcards
List some protective purposes of earwax
Mechanical protection
Slightly acidic = protect against bacterial and fungal infection
Traps dirt, repels water
Aids removal of organisms
Lubricate ear canal
What are the symptoms of earwax?
(I think they mean excessive, idk)
Discomfort (blocked/full)
Can be itchy
Gradual reduction in hearing
Dizziness, tinnitus (less common)
What contributes to excessive earwax?
Overactive ceruminous glands
narrow ear canal, large amount of hair in canal
Insufficient talking/chewing
Age - earwax becomes drier and harder
Outline the steps for ear examinations
1) Take history, 2) wash hands, 3) inspect external ear for redness/swelling 4) apply pressure to mastoid area directly behind pinna, 5) move pinna up and down, manipulate the tragus, 6) examine the EAM
What questions can you ask to identify excessive earwax?
Can you describe your symptoms? How did they develop?
How painful is it on a scale from 0 to 10?
Have you experienced this before? If so, how did you manage it? Did it work?
Is there a history of trauma to your ear?
What medicines do you take?
Name some differential diagnoses for earwax (compaction??)
(they’re not very clear on the slides…)
Otitis externa = inflammation/infection of outer ear (redness/inflamm, itch)
Otitis media = middle ear infection (pain, fever, history of cold)
Inner ear = dizziness, tinnitus
Trauma to ear canal = laceration of the ear canal after cleaning with pens, cotton buds
Foreign bodies = similar symptoms as ear wax initially, discharge and pain over time, common in children.
What are the goals of treatment for earwax
Relieve symptoms/ improve quality of life, reduce risk/prevent complications
Soften and aid removal of ear wax
Manage with evidence based treatment
How is wax impaction treated?
> 30% clear in 5 days without treatment
Avoid cotton bud and ear candle use
Ear syringe by doctor is effective = flush ear with warm water or saline
- can be done prior or after earwax softeners
Comment on the use of Cerumenolytics in earwax compaction
Able to loosen/soften wax to aid removal, all have similar efficacy.
Safe in children and no medicine interactions
ADRs = few, local irritation, brief deafness inc
Precautions = peanut or almond oil allergy, irritation or rash occurs
Contraindication = inflammation in ear canal, perforation of eardrum
What medications can be used in treatment of external ear conditions? (e.g. earwax compaction/earwax)
Carbamide peroxide (ear clear)
Dichlorobenzene with chlorbutol (cerumol)
Docusate (waxol)
Instructions of use and notes for carbamide peroxide (Ear clear) use
Adults + children >12 y/o
5-10 drops, up to 4 days. DO NOT plug ear
Mild temporary effervescence
Instructions of use and notes for Dichlorobenzene with chlorbutol (cerumol) use
No age limit, contains arachis oil (peanut allergy?)
Up to 5 drops twice daily, few days
Plug ear with ear-drop moistened cotton plug
Instructions of use and notes for docusate (waxol) use
Fill ear for 2 consecutive nights
When to refer for ear wax conditions?
Signs of middle ear involvement (e.g. pain, fever, malaise)
Signs of inner ear involvement (e.g. dizziness, tinnitus)
Pain beyond discomfort, medication not working/making it worse
Potential trauma or foreign body
Provide useful patient information about earwax
Wax keeps ears clean/protective function
Wax build up/impaction generally harmless and will resolve
Talking/chewing helps earwax move out
Avoid cleaning ears with cotton buds (best prevention)
