Includes eardrum, ossicles, and eustachian tube
middle ear
From the external ear through the middle ear
ex. wax, ear infection (otitis externa, performation of eardrum)
Conductive phase hearing loss
involves the cochlea and cochlear nerve
sensorineural hearing loss

nasal septum
Lateral wall is formed by the ________ and their corresponding meatus.
turbinates
(middle, superior, and inferior)
Can only check these sinuses during an exam:
frontal
maxillary

When examining the head, examine 5:
- hair
- scalp
- skull
- face
- skin
When examining the eye, use the _____ eye chart
snellen
What is important to check in the eye exam?
pupils: inspect size, shape, and symmetry using pupil size card and test reaction to light
If shine light in one eye and other eye constricts, then ____ ____
consensual reaction
If shine in eye and get a reaction
direct reaction
The rhythmic oscillation of the eyes is called
nystagmus
During the opthalmoscopic exam, can detect illnesses:
- glaucoma
- diabetes
- meningitis
- subarachnoid hemorrhages
- trauma
- brain masses
- uncontrolled hypertension
If there is ear pain and testing for an ear infection,
- move auricle up and down,
- press tragus

What test compares air conduction and bone conduction
Rinne test
_____ _____ tests for lateralization.
Weber test
For a nasal intubation, check for which airway is less deformed by looking up the nasal vestibule. True or false?
The rise of the soft palate is innervated by CN ___
10
When examining the neck
Inspect
- Alignment/symmetry of cervical spine
- Overlying skin for scars, deformities, skin color changes
- Atlanto-occipital joint
- Thyromental distance
- Sternomental distance
- Position of trachea
- Thyroid gland
- Voice quality
Should ask about airway history:

- previous prolonged intubations
- smoking
Clues to a difficult intubation
- dry cough
- easy bleeding
- GERD
- diabetes mellitus (limited cervial mobility)
- loud snoring (tissue obstruction)
- major trauma
- radiation to the neck
