Flashcards in Ears Eyes, Nose and Throat WPPII Deck (22):
1

Outer ear consists of:

1) Pinna
2) External Auditory Canal

2

Outer ear sound through tissue or air?

Air

3

Middle ear consists of:

Tympanic Membrane (Ear Drum)
- Malleus (hammer)
- Incus (anvil)
- Staples (stirrup)
Middle Ear is an AIR filled space with structures.

4

What are the smallest bones in the body?

Inner Ear Ossicles: Malleus / Incus / Staples

5

What is the function of the inner ear structures?

To amplify sound vibrations

6

What is the function of the Auditory Tube?

To equalize pressure

7

1) Exists within the temporal Bone
2) Located in the Bony Labyrinth
3) Filled with fluid called Perilymph

The Inner ear

8

Membranous labyrinth filled with endolymph.

Inner ear

9

What structure is responsible for hearing?

cochlea, a membranous structure in the inner ear.

10

Special Neurons called Hair Cells.

Receptors in cochlea for hearing.

11

Oval Window

A structure in the inner ear where perilymph vibrates

12

At which end does the cochlea receive high pitch frequencies?

Larger end.

13

What nerve takes the sound to the brain?

Vestibular Cochlear Nerve

14

Vestibular System regulates what?

Balance (semi-circular canals) fluid sloshes with movement and causes hair cells to move

15

Otoliths

Give sense of equilibrium

16

Vertigo is an inflammation of what?

Semi-Circular Canals

17

Dizziness

1) Lightheadedness
2) Vertigo

18

Otoscope

see inner ear

19

Conductive versus Sensorineural hearing loss?

1) outer, middle ear
2) Inner ear (Presbycusis)

20

The most common bacterial pathogens implicated in causing otitis media (OM)

are Streptococcus pneumoniae,

21

Otitis Media

Exam findings in OM include a red bulging tympanic membrane that does not move well with pneumatic otoscopy, an opaque tympanic membrane with pus behind it, obscured middle-ear land marks, and if the tympanic membrane has ruptured, pus in the ear canal.

22

Best therapy for Acute Otitis Media

Tylenol, waiting, or oral antibiotics
