2WW for MRI
<3cm: Radiotherapy
>3cm: Surgical excision
What ear conditions cause pain?
Otitis externa
Otitis media
Mastoiditis
How can you differentiate between otitis externa, media and mastoiditis in terms of
Symptoms
History
Otoscopy
OE // AOM // Mastoiditis
Discharge and itchy // conductive hearing loss, fever // Severe pain, protruding ear, systemic unweel
Hx swimming // URTI // otitis media
red swollen, flaky canal // buldging tympanic membrane // possible perforation, ear discharge
How do you treat otitis externa?
1st: topical antibiotics (acetic acid) +/- steroid
+ oral abx/antifungals if spreading
Failsure: ENT referral
What do you do with a diabetic with deep ear pain, discharge and temporal headaches

Give if…
- >4 days
- systemically unwell without admission need
- Vulnerable (<2yrs, IC)
- Perforation or discharge in canal
-
What is the treatment for mastoiditis?
IV antibiotics
What are the complications of mastoiditis?
Meningitis
Hearing loss
Facial nerve palsy
How does cholesteatoma difer from otitis or mastoiditis?
Non painful
Smelly discharge
Conductive hearing loss
Hx cleft palate
What does the following show on otoscopy?
Attic crust (red arrow), bone (blue arrow)
Cholesteatoma
How do you manage cholesteatoma?
Refer to ENT for CT petrous bones
Painless conductive hearing loss in a young child indicates what and how do you treat it?
Glue ear
Grommet for 10 months
Adenoidectomy
How does presbycussis and otosclerosis compare in terms of…
Hearing loss
Age of onset
Tinnitus
Presbycussis // Otosclerosis
Bilateral conductive // Bilateral sensory
Increases with age // 20-40s, family history
Common // Uncommon
How do you confirm presbycusis?
-ve otoscopy, tympanometry and inflammatory markers
How can you tell if tonsillitis would benefit from antibiotics
CENTOR >=3 OR FeverPAIN >=4
Fever >38 degrees
Purulence
Acute onset (FeverPain)
Inflammation
No cough
For tonsilitis, what is the
Bacterial cause
Antibiotic therapy
Group A strep (pyogenes)
1st: Pen V (phenpen) 10 days (doxy, clarithromycin)
When would a tonsillectomy be considered?
7 bouts in 1yr
5 bouts in 2 yrs
3 bouts in 3 yrs
What is the management pathway for sinusitis
Conservative for 10 days
> 10 days, bacterial cause unlikely: Nasal spray
>10 days, bacterial cause likely: PhenPen
How is post-tonsillectomy bleeding managed?
6-8hrs: Theatre
5-10 days: Admit for IV antibiotics
