Features of otitis externa?
- Otalgia, itch, discharge
- Otosocopy - red, swollen or eczematous ear canal
Outline management for otitis externa
- Topical antibiotic or combined antiobitic with a steroid (note if TM is perforated typically aminoglycosides are not used). If you suspect fungal otitis externa use canesten drops
- If there is canal debris - consider removal
- If the canal is extensively swollen sometimes a pope ear wick is used
- Swab the ear
SECOND LINE: - Oral antibiotics e.g. fluclox if infection is spreading
- Empirically use antifungal agent
In suspected otitis malignant otitis externa (elderly diabetics, cranial nerve involvement etc)
- IV antibiotics
List some complications of tonsillitis
- Otitis media
- Quinsy
- Rheumatic fever and glomerulonephritis very rarely
Outline the indications for tonsillectomy
- 7,5,3 rule - 7 episodes per year for one year
- 5 episodes per year for 2 years
- 3 episodes per year for 3 years
- Suspected malignancy (irregular often asymmetrical tonsillar enlargement, etc)
- Recurrent febrile convulsions secondary to episodes of tonsillitis
- Obstructive sleep apnoea, stridor or dysphagia secondary to enlarged tonsils
- Peritonsillar abscess (quinsy) if unresponsive to standard treatment
When is a primary post-tonsillectomy bleed and when is secondary?
Also what are primary and then what are secondary bleeds most commonly caused by?
Primary = < 24 hours - most commonly due to inadequate haemostasis
Secondary = 24 hours to 10 days - most commonly due to infection
What is the most common symptom in nasal septal haematoma?
Then list some more features
Sensation of nasal obstruction
Pain
Rhinorrhoea
Bilateral, red swelling arising from the nasal septum
Can be differentiated from a deviated septum by gently probing the swelling. Nasal septal haematomas are typically boggy whereas septums will be firm
How can nasal septal haematomas be differentiated from nasal deviation?
Surgical drainage
IV antibiotics
What is the complication that happens when you don’t manage nasal septal haematoma?
If untreated, irreversible septal necrosis may develop within 3-4 days. Due to pressure related ischaemia of the cartilage resulting in necrosis. Can result in saddle-nose deformity
What decibel level is normal in audiograms?
0-20dB
List some differentials for facial pain
- Trigeminal neuralgia - severe lancinating pain along one or more branches of the trigeminal nerve
- Sinusitis - facial pain accompanied by symptoms such as nasal discharge or congestion suggesting sinusitis
- Dental problems - dental caries or abscesses can cause localised facial pain
- Tension type headache
- Migraine
- GCA

Nystagmus
Romberg’s +ve
Sensation of aural fullness or pressure
Outline the management of Meniere’s disease, including advice, what is given for acute attacks and what is given for prevention of attacks?
