Q

what are the external, middle, and inner ear infections?

A

Otitis externa: Also known as swimmer’s ear, this infection affects the skin and soft tissue of the ear canal. It can occur if water remains in the ear after swimming or bathing, or if the ear canal is irritated by a cotton swab. Symptoms include pain, itchiness, discharge, and sometimes a golden crust.
Otitis media: This infection affects the air-filled space behind the eardrum. It can be caused by bacteria or viruses, such as those that cause colds. Symptoms include pain, fever, and tugging at the ear

Q

why do we pull the pinna up for adults but down for children during an exam

A

this is because the adults canal is in an S shape, and kids canals are shorter (which is why they sometimes get more infections)

Q

what is the whispered voice test

A
  • Test one ear at a time while masking hearing in the other ear by placing one finger on the tragus and rapidly pushing it in and out of
    the auditory meatus
  • Shield your lips so the person cannot compensate for a hearing loss (consciously or unconsciously) by lip reading or using the “good” ear
  • Stand arm’s length behind the person(2 ft.) from the person’s ear, exhale, and whisper slowly some two-syllable words (one ear at a
    time)
  • Normally, the person repeats each word correctly after you say it

Q

what do tuning fork tests do

A
  • Measure hearing air conduction (AC) or bone conduction (BC), in which sound vibrates through cranial bones to the inner ear
  • AC route through the ear canal and middle ear is usually the more sensitive route
  • To activate the tuning fork, hold it by
    the stem and strike the tines softly on the back of your hand
  • Perform Weber and Rinne tests
