Hearing loss: No HL
Microtia correct answers Congenital OE Disorder.
small or absent pinna. Tragus & EAC are absent.
Treatment: Surgical options around age 5-7.
3 stages of reconstruction.
Hearing loss: CHL. Variable. only pinna absent: minimal HL. entire OE & pinna absent:
moderate HL.
Atresia correct answers Congenital OE Disorder.
Associated with: Treacher-Collins. Trauma, burns. Can be in conjunction w/ Microtia.
Characteristics: External Canal not formed. More common in males. Middle ear bone
abnormalities common.
Treatment: Surgery to remove bony plate. Canalplasty.
Hearing loss: unilateral or bilateral.
Stenosis correct answers Congenital OE Disorder.
Narrowing of ear canal. Varying degrees. Easily clogged by wax.
Treatment: canalplasty
Hearing loss: no HL
Foreign Bodies correct answers OE Disorder.
Placed in external ear canal. (bead, pencil, lead, beans, etc.
Treatment: medical intervention.
HL: can cause HL if occluding occurs
External Otitis correct answers OE Disorder.
Water w/ bacteria/fungus gets trapped in ear canal. Ear feels blocked, itches, drainage, sensitive
to touch.
Treatment: Oral and/or topical antibiotics.
To prevent: OTC drops, keep ear dry.
HL: HL possible, but variable. Difficult to evaluate if severe pain
Wax correct answers OE Disorder.
Some is good to remove debris. Too much can create HL, discomfort, ringing.
Treatment: Soften wax with OTC drops. Health care provider removes w/ irrigated H20 or
curette. DO NOT USE Q TIPS.
HL: Too much = mild CHL.
Tympanometry: Type A: no blockage.
Type B: completely blocked
, Collapsing Canal correct answers OE Disorder.
Narrowing of the external canal that occurs w/ pressure compresses the pinna against the side of
head. More common in unusually large ears.
Treatment: no medical intervention.
HL: Unilateral or bilateral. High frequency CHL
Tumors correct answers OE Disorder.
Most common in canal are basal cell.
Treatment: immediate medical intervention.
HL: variable depending on type and size.
Perforations correct answers OE Disorder.
Excessive build up during a middle ear infection. Trauma from pointed objects. Sudden
explosions.
Treatment: Medical referral. Keep dry. Usually heal spontaneously. Myringoplasty.
HL: variable CHL.
Otitis Media correct answers ME Disorder (mass).
Presence of fluid/infection causes CHL. Fluid may take weeks to months to resolve. HL may
continue to be present after the infection has resolved itself.
Mastoiditis correct answers Invasion of the fluid into mastoid bone. If left untreated, infection
can eat away at bone and tissue behind the ear.
A CT scan of head or mastoid may show infection has spread beyond middle ear
Symptoms of Otitis Media correct answers Fever, ear pain, HL, irritability, pulling on ear, poor
sleep, drainage.
Prevention of Otitis Media correct answers Prophylaxis, Breast feed, avoid smoke, wash hands,
vaccinations, avoid pacifiers, smaller day care rooms.
Interventions of Otitis Media correct answers Watchful waiting, antibiotics, PE Tubes,
Myringotomy, Politzerization, Valsalva maneuver.
Cholesteatoma correct answers ME Disorder (mass).
Nonmalignant tumor in ME space. Skin has entered ME space. Small sac like tumor made up of
proteins, fats & tissue. As it grows, damage the bones in ME.
Symptoms of Cholesteatoma correct answers HL, drainage w/ foul odor, ear pressure, dizziness,
facial weakness
Interventions of Cholesteatoma correct answers ENT: mastoidectomy. Keep ear dry. Antibiotics,
CT scan-MRI. Audiological: post op results.
