1

Labyrinthitis

-acute onset
-continuous
-severe
-hearing loss
-tinnitus

2

Labyrinthitis - Treatment

abx if febrile

3

Menieres disease

-episodic vertigo
-last minutes to hours
-low frequency sensorineural hearing loss
-tinnitus

4

Menieres disease - treatment

diuretics

5

Most common vertigo

BPV

6

BPV

-recurrent
-associate with changes in head position
-sxs occur in clusters that persist for several day
-epley maneuver
-Recurrent case: MRI

7

MS

-episodic vertigo
-chronic imbalance
-unilateral hearing loss
-rapid onset
-spontaneous recovery may occur

8

Vertebral artery insufficiency

-MC in elderly
-triggered by posture changes or neck extension
-reduced flow in vertebrasilar system
-confirm with MR angiography

9

Vestibular schwannoma

-benign lesion of internal auditory canal
-unilateral hearing loss
-diminished speech discrimination
-enhanced MRI


10

Vascular compression

compression of 8th CN causing imbalance

11

Vestibular neuronitis

-herpes vestibular ganglion
-unilateral
-can last for several days

12

Ear drops

Carbamide peroxide 6.5% OTC

13

Carbamide peroxide 6.5% do not use if

history of infections, perforations or otologic surgery

14

prostaglandins

lantanoprost

15

Lantanoprost

increase aqueous humor outflow

16

Lantanoprost AE

-patient with blue or green become brown
-stimulates eye lash growth

17

Beta-blockers

timolol

18

Timolol

decrease aqueous humor production

19

Alpha-2 agonists

Brimonidine

20

Brimonidine

decreased aqueous humor production

21

Carbonic anhydrase inhibitors

dorzolamide

22

Dorzolamide

decrease IOP

23

Cholinergic agonists

pilocarpine

24

Pilocarpine

causes miosis
-increase aqueous humor outflow

25

First Generation Histamines

-more lipophilic
-Cross BBB
-"sediating"
-paradoxically can be activation - espcially in kids
-hight anticholinergic effects

26

Second Generation Histamines

-less lipophilic
-less BBB permeation
-"less/non sedating"
-longer duration of action

27

Oxymetazoline - Uses

decongestant, very potent

28

Oxymetazoline

no more than 3 days - risk of rebound nasal congestion

29

Antitussives

benzonatate

30

Benzonatate -MOA

direct action on receptors in the cough center of the medulla
