Auricular Hematoma aka
Trauma causes bruising and swelling
Scarring or thickening of the cartilage can develop.
treatment of auricular hematoma
Treatment: Surgical and prevention
what happens if auricular hematoma isn't treated
becomes cauliflower ear
if affects pinna, still able to hear
potential to have hearing loss if canal is disrupted
Benign lesion formed by connective tissue.
over response from body
keloids: Individuals with more _____________ tend to develop keloids more readily but occurs in all races.
Pinna subject to repeated sun exposure.
Patients can't always visualize pinna.
If you see a lesion, make patient aware of it.

hyper ceruminosis treatment
Treatment is frequent removal
is hard ear wax
almost like scabbed
Cerumen Impaction incidence
5% normal adults
34% nursing home / institutionalized
cerement impaction causes
Use of Q-tips
Decreased expulsion from canal
cerumen issues what are the two
impacted and occluded
"Pressed together firmly", or "packed tightly". Often dark colored because it has been there a long time. Needs to be. Does NOT cause hearing loss.
Stopped up, closed up, or obstructed. Completely blocks the canal. Needs to be removed. DOES cause hearing loss.
foreign bodies removal info
Removal is not within audiology scope of practice.
Refer to physician.
May require surgery if the patient isn't cooperative or if the object is impacted.
foreign bodies approaches to removal
Choice depends on the size and shape of the object.
Goal is to avoid pushing the object into the middle ear or lacerating the canal Curettage
foreign bodies Irrigation works well for sand and small objects deep in the canal.
If object is in contact with the TM, can be very uncomfortable.
foreign bodies Insects and some other biological material
hould not be removed with water irrigation, which can cause the foreign object to swell.
Kill live insects by irrigating with alcohol or mineral oil before removing.
Abrasion of canal
Epithelial lining of canal is thin and easily damaged. Can occur from medical cleaning or from cotton- tipped applicators.
Caused by aggressive use of cotton-tipped applicator. Can precipitate infection (otitis externa).
Growths / Tumors
Result from exposure to cold water
Ear plugs prevent recurrence
Can occlude the canal/block cerumen
Projecting masses of swollen and hypertrophied or tumorous membrane
Benign tumor resulting from an overgrowth of epithelial tissue on vascularized connective tissue.
Benign tumors consisting mainly of fibrous tissue.
doctors will watch
Caused by deficiency in supporting cartilage. Seen particularly in elderly. May be aggravated by headphone placement, resulting in erroneous estimation of hearing thresholds.
collapsing ear canal
