Q

How can bottle feeding increase the risk of otitis media?

A

1) The strong swallow required to feed from a breast induces a sizeable negative pressure in the infants oral cavity allowing eustachian tube insufflation. Bottle feeding however, relies more on gravity from the bottle, and less negative pressure is required.

2) Breast milk provides maternal antibodies against common OM pathogens.

Q

Pathophysiology in otitis media?

A

1) OM occurs 2ary to oedema and narrowing of the eustachian tube

2) An oedematous eustachian tube prevents the middle ear from draining –> predisposed to colonoisation

Q

Purpose of the eustachian tube?

A

The eustachian tube serves to equalise pressure in the middle ear, when the tube is blocked this cannot happen.

Q

Why are children predisposed to OM?

A

1) their esutachian tubes are narrower and more prone to blockage

2) their eustachian tubes are more horizontal, inhibiting drainage (why the pinna is pulled down for paediatric examination, and up for adults)

3) children have less developed immune systems are are more prone to upper respiratory tract infections (a common cause of eustachian tube oedema)

35
Q

What is involved in tympanometry?

A

The procedure involves changing the pressure in the outer ear, playing a tone and analysing the reflected sound waves.

The degree of reflection gives a good proxy measurement for the admittance of the TM (the amount of energy transmitted through the TM).

The admittance will be at its maximal point when the pressures on either side of the TM are equal.

5) Seizures and symptoms of intracranial infection (rarely presenting symptoms)

60
Q

Key exam findings in mastoiditis?

A

1) fever

2) usually bulging tympanic membrane with clear fluid level or perforation with purulent discharge from the ear.

5) cervical lymphadenopathy on affected side.

61

1) CT head with contrast:
- will demonstrate the extent of mastoid air cell opacification
- an also identify intracranial infection and the extent of this

2) MRI head:

Early IV Abx

63

A

vaccination against Haemophilus influenzae and Streptococcus pneumoniae

65
Q

Surgical options for mastoiditis?

A

In addition to Abx:

1) Myringotomy and grommet insertion: to help infection drain via the middle ear.

2) Mastoidectomy: to drill out the mastoid bone and allow the infection to drain

66
Q

Complications of mastoiditis?

A

The complications of untreated mastoiditis are a result of the infection progressing and causing damage to surrounding neurological structures:

1) Conductive hearing loss

2) Sensorineural hearing loss & vertigo

3) If infection enters facial canal –> facial nerve damage, ipsilateral facial weakness

4) If erosion of mastoid into cranial vault:
- meningitis
- formation of subdural empyema
- intracerebral abscess formation

67
Q

What can cause conductive hearing loss in mastoiditis?

A

Due to a middle ear effusion from co-existing acute otitis media or due to infection causing destruction of the ossicles.

68
Q

What can cause sensorineural hearing loss & vertigo in mastoiditis?

A

If the inner ear is affected by progressive mastoid destruction.

69
Q

is there forehead sparing in facial nerve damage in mastoiditis?

no (due to the lower motor neurones being affected)

70
Q

What branch of the facial nerve runs through the middle ear?

A

The corda tympani branch of the facial nerve.

A

FeverPAIN: >/=4
Centor: >/=3

107
Q

What is a ‘delayed’ prescription in tonsillitis?
