Q

How is malignancy otitis externa treated?

A

Systemic antibiotics

21
Q

What are the pathologies of the middle ear?

A
Otitis media with effusion
Acute otitis media
Chronic supprative otitis media
Tympanosclerosis
Otosclerosis
22
Q

What causes otitis media with effusion?

A

Eustachian tube not working, meaning middle ear pressure can’t be stabilised
This causes a vacuum to be created and fluid to be secreted as a result

23
Q

What is the treatment of otitis media with effusion?

A

Grommet insertion

24
Q

What is acute otitis media?

A

Inflammation of middle ear accompanied by signs and symptoms of an ear infection

25
Q

What are the types of chronic supprative otitis media?

A

Perforated tympanic membrane

Cholesteatoma

26
Q

What causes a perforated tympanic membrane?

A

Otitis media
Barotrauma
Noise, foreign objects, severe trauma

27
Q

How is a perforated eardrum treated?

A

Usually resolve spontaneously

28
Q

What causes cholesteatoma?

A

Eustachian tube dysfunction creates vacuum in middle ear pulling tympanic membrane into middle ear and creating a cyst that can turn into cholesteatoma

29
Q

What is tympanosclerosis?

A

Calcium deposits in tympanic membrane

30
Q

What is otosclerosis?

A

Extra bone formed in the ear

31
Q

What does otosclerosis cause?

A

Conductive hearing loss but normal tympanic membrane

32
Q

What are the inner ear pathologies?

A
Presbyacusis
Noise induced hearing loss
Ototoxic medications
Meniere's disease
Head injury
Infections
Vestibular schwannoma
33
Q

What is presbyacusis?

A

Age associated high frequency hearing loss

34
Q

What is a vestibular schwannoma?

A

Benign tumour causing sensorineural hearing loss in 1 ear

35
Q

What is benign positional vertigo?

A

Otoconia in semicircular canals

36
Q

What are the clinical features of benign positional vertigo?

A

Q

What is the treatment for benign positional vertigo

A

Epley manoeuvre

38
Q

39
Q

What are the clinical features of vestibular neuritis?

A

Spontaneous vertigo
No associated symptoms
Can last a few days several times

40
Q

What is the treatment of acute and chronic vestibular neuritis?

A

Acute- vestibular sedatives

Chronic- vestibular rehabilitation
