Q

What test can be used to diagnose peripheral causes of vertigo?

A

Head impulse test
Examiner holds the patient’s head and rapidly jerks it 10-20 degrees in one direction while the patient continues looking at the examiner’s nose. The head is slowly moved back to the centre before repeating in the opposite direction
Patient with a normally functioning vestibular system will keep their eyes fixed on the examiner’s nose.
Patient with an abnormally functioning vestibular system (e.g., vestibular neuronitis or labyrinthitis), the eyes will saccade (rapidly move back and forth) as they eventually fix back on the examiner.

Q

What is the pathophysiology of vestibular neuronitis?

A

Inflammation in the vestibular nerve distorts the signals travelling from the vestibular system to the brain, confusing the signal required to sense movements of the head. This results in episodes of vertigo, where the brain thinks the head is moving when it is not.

164
What is a normal Rinne's test?
If the patient can hear the sound in the air after they stopped hearing it on the bone, it suggests air conduction is better than air conduction --> normal --> "Rinne's positive"
