Q

Cauliflower ear

A
  • Cauliflower ear (complication of hematoma auris, perichondrial hematoma, or traumatic auricular hematoma) is a condition that occurs when the external portion of the ear suffers a blow, blood clot or other collection of fluid under the perichondrium.
  • This separates the cartilage from the overlying perichondrium that supplies its nutrients, causing it to die and resulting in the formation of fibrous tissue in the overlying skin.
  • As a result, the outer ear becomes permanently swollen and deformed, resembling a cauliflower.

Q

tympanosclerosis

A

scar tissue along tympanic membrane
multiple infections can lead to this
kids that have had tubes usually have a little tympanosclerosis depending on how long the tubes were in

17
Q

mechanics of hearing

A

Two separate (but connected) mechanisms (Conductive and Sensorineural)

18
Q

conductive hearing

A
  • Sound waves vibrate through the air, through the ear canal, to the tympanic membrane, vibrating the ossicles.
  • Alternatively, sound waves can vibrate through bone, and directly vibrate the ossicles, bypassing the tympanic membrane.
  • Conductive hearing loss: ear canal blockage, perforation of TM, or problem with the ossicles.
19
Q

sensorineural hearing

A
  • The ossicles transmit vibrations to the oval window, which in turn transmits vibrations into the cochlea, which is lined with specialized receptors. These send signals to the brain via the cochlear nerve (CN VIII).
  • Sensorineural hearing loss: disruption of the neural pathway, either in the inner ear or in the brain.
20
Q

Evaluation of Hearing ability

A

-“Gross” evaluation includes finger rub or whispered voice
Patient occludes one ear
-Examiner rubs fingers and checks distance at which patient can still hear
-Whisper a word behind patient, ask patient to repeat word

21
Q

special tests for evaluating hearing loss

A

If you note a patient with decreased hearing acuity: Grab your tuning fork and perform the following two tests

  • Rinné (compares air conduction and bone conduction)
  • Weber (tests for lateralization)
22
Q

Rinne Test

A
  • Place handle of tuning fork on mastoid process. Ask patient to raise hand when she can no longer hear it. Then hold the fork close to the ear.
  • In a normal ear, air conduction is greater than bone conduction (patient will hear the forks).
  • In an ear with conductive hearing loss, bone conduction is greater than air conduction (patient won’t hear the forks).
  • In an ear with sensorineural hearing loss, overall hearing is decreased, but air conduction is greater than bone conduction (like in a normal ear).
23
Q

Weber Test

A
  • Place the vibrating tuning fork on the top of the patient’s head.
  • If sound lateralizes to the BAD ear, then conductive hearing loss is present. This is because bone conduction is still functioning normally.
  • If sound lateralizes to the GOOD ear, then sensorineural hearing loss is present. The sound is not getting transmitted via the nerve to the brain in the bad ear.
24
Q

inspection and palpation of the nose
