1

What do you treat otitis media with?

Oral Amoxycillin, 15mg/kg, 8 hourly

 

Cefuroxime if allergic

2

When are antibiotics given in otitis media?

<2 years

Perforation

Cochlear implant

Indigenous

It is the only hearing ear

Immunodeficient

Complications - mastoiditis, facial paralysis

3

Explain Weber's test and how it is interrupted?

A vibrating tuning fork is placed on a boney prominence, equidistant from both ears

Patient reports where they hear the buzzing

 

If there is a conductive hearing loss then the sound will be louder in the effected ear as bone conduction will compensate

If there is sensorineural loss then it will be heard in the unaffected ear

4

What pitch is worse heard with sensorineural hearing loss?

High pitch

5

How is chronic suppurative otitis media characterised?

Tubotympanic disease - "safe"

Atticoantral disease - "unsafe"

6

What are some complications from cholesteatomas?

Conductive or sensorineural hearing loss

Vertigo

Facial paralysis

Intracranial pathology

7

How is Ramsay-Hunt mananged?

Steroids

Acyclovir if within 3 days

Eye patch and artificial tears if facial nerve involvement

8

What is a cholesteatoma?

A squamous epithelium trapped in the temporal bone that can be congenital or secondary to tympanic membrane pathology

9

What structures can refer pain to the ear?

Teeth

Sinuses

Throat

Cervical neck

Larynx

Temporomandibular

10

What is Rinne's test? How is it interrupted?

Place the vibrating fork on the mastoid process

If bone conduction is better than air then there is conductive hearing loss 

11

What symptoms do you get with vestibular neuritis?

Persistent vertigo following an acute infection

 

No hearing loss or tinnitus

12

What manoeuvres are used in BPPV? What is the function of each one?

The Dix-Hallpike - Diagnosis

Epley - Treatment

13

How is Meniere's treated?

Diazepam or prochlorperazine for acute attacks

 

Lifestyle modification

Low salt diet

Thiazide diuretic or betahistine

Surgery

14

What is the pathophysiology of BPPV?

Otoliths from the utricle become loose and lodge in the posterior semicircular canal

15

Which symptoms do you get with meniere's disease?

Intermittent vertigo - >30 minutes but <1 day

Tinnitus

Hearing loss

Fullness in the ear

16

What is a potential complications of acute otitis media?

Chronic otitis media

17

What are some common causative agents of otitis media?

Streptococcus pneumoniae

Haemophilus influenzae

Moraxella catarrhalis

18

What is chronic suppurative otitis media? What symptoms do patients get?

Recurrent or persistent bacterial infection that causes irreversible damage to the tympanic membrane and some the ossicles resulting in conductive hearing loss

 

Hearing loss

Itch

Discharge

19

What is Ramsay-Hunt syndrome? What are the symptoms?

Reactivation of herpes-zoster in the facial nerve ganglion

Ear pain

Ataxia

Facial paralysis

Hearing loss

20

Who should get middle ear ventilatory tubes?

OME for 4 months with other symptoms

Recurrent OME in an at risk group

OME and structure damage to the tympanic membrane

21

Which part of the brain controls hearing?

Temporal lobe of the cerebral cortex
