17
Q

What abx can be given for prolonged / complicated otitis media?

A

5-7 day course of amoxicillin is first-line
erythromycin or clarithromycin if pencillin allergic

18
Q

What are the potential complications of acute otitis media?

A

mastoiditis
meningitis
brain abscess
facial nerve paralysis

19
Q

How may allergic rhinitis present?

A

sneezing
nasal pruritus
bilateral nasal obstruction
clear nasal discharge
post-nasal drip

20
Q

How can allergic rhinitis be managed?

A

allergen avoidance

mild-to-moderate sxs:
oral or intranasal antihistamines

moderate-to-severe sxs:
intranasal corticosteroids

a short course of oral corticosteroids are occasionally needed to cover important life events

21
Q

Short courses of topical nasal decongestants (e.g. oxymetazoline) can be used to control allergic rhinitis.

Why can longer courses not be prescribed?

A

increasing doses are required to achieve the same effect (tachyphylaxis)

rebound hypertrophy of the nasal mucosa (rhinitis medicamentosa) may occur upon withdrawal

22
Q

How do cholesteatomas present?

A

foul-smelling, non-resolving otorrhea
hearing loss

local invasion:
vertigo
facial nerve palsy
cerebellopontine angle syndrome

23
Q

How can cholesteatomas be investigated and managed?

A

Otoscopy: ‘attic crust’ - seen in the uppermost part of the ear drum

Management: referred to ENT for consideration of surgical removal

24
Q

What can cause severe hearing loss in children?

A

Genetic (up to 50% of cases)
idiopathic (up to 30% of childhood deafness)
Infectious e.g. post meningitis
Congenital e.g. maternal CMV, rubella or varicella

25
Q

What can cause severe hearing loss in adults?

A

Viral-induced sudden hearing loss
Ototoxicity e.g. aminoglycoside antibiotics or loop diuretics.
Otosclerosis
Meniere disease
Trauma

26
Q

Give some causes of neck lumps

A

Reactive lymphadenopathy
Lymphoma
Thyroid swelling
Thyroglossal cyst
Branchial cyst
Pharyngeal pouch
Cystic hygroma

Carotid aneurysm

27
Q

How does presbycusis present?

patients may describe difficulty following conversations

Audiometry shows bilateral high-frequency hearing loss

28
Q

How does otosclerosis present?

positive family history

29
Q

secondary problems such as speech and language delay, behavioural or balance problems may also be seen

30
Q

How does Meniere’s disease present?

Q

How do acoustic neuromas present?

A

cranial nerve V (trigeminal): absent corneal reflex
cranial nerve VII (facial): facial palsy

olive oil
sodium bicarbonate 5%
almond oil

tx should not be given if a perforation is suspected or the patient has grommets

33
Q

How does otitis media with effusion present?

A

secondary problems such as speech and language delay, behavioural or balance problems

34
Q

How can otitis media with effusion be managed?

A

first presentation of otitis media with effusion is active observation for 3 months - no intervention is required

smoking
viral illness
hypothyroidism
gastro-oesophageal reflux
laryngeal cancer
lung cancer

36
Q

Mastoiditis typically develops when an infection spreads from the middle to the mastoid air spaces of the temporal bone.

How does it present?

A

otalgia: severe, classically behind the ear
fever
may be a history of recurrent otitis media
the patient is typically very unwell

37
Q

Examination findings for mastoiditis?

A

swelling, erythema and tenderness over the mastoid process
the external ear may protrude forwards
ear discharge may be present if the eardrum has perforated

38
Q

How can mastoiditis be investigated and managed? Complications?

A

Clinical dx / CT if complications suspected
Mx: IV antibiotics

Complications:
facial nerve palsy
hearing loss
meningitis

39
Q

Meniere’s disease is a disorder of the inner ear characterised by excessive pressure and progressive dilation of the endolymphatic system.

How does it present?

A

Meniere’s in Middle Age
episodes last Minutes to hours

typically unilateral
recurrent episodes of vertigo, tinnitus and hearing loss (sensorineural)
a sensation of aural fullness
nystagmus and a positive Romberg test

40
Q

How can Meniere’s disease be managed?

A

ENT assessment

patients should inform the DVLA
cease driving until satisfactory control of symptoms is achieved

acute attacks: buccal or IM prochlorperazine
prevention: betahistine and vestibular rehabilitation exercises may be of benefit

41
Q

What are your top differentials for a patient with a new parotid lump? How would you ask about these?

A

Pleomorphic adenoma
Mumps

Salivary glands stones
