characteristic features with allergic rhinitis
nasal pruritus, sneezing, rhinorrhoea and nasal congestion
what is allergic rhinitis often associated with
allergic conjunctivitis
what is allergic rhinitis
where your nose gets irritated by something youβre allergic to
what type of hypersensitivity reaction is allergic rhinitis
type 1
it is an IgE mediated response to allergens
mx of allergic rhinitis
initial measures
avoiding triggers
nasal irrigation with saline
intra-nasal or oral anti-histamines
mx of allergic rhinitis if initial measures are ineffective
intra-nasal steroids
oral steroid for sever and/or short term cases
why is BPPV predominately seen in elderly population
due to deposition of calcium deposits within the semicircular canals
clinical features of BPPV
provoked by movements of head usually to one side when turning in bed or looking up
episodes last 30 seconds to 1 minute
no hearing loss or tinnitus
how to diagnose BPPV
dix-hallpike manoeuvre
the test is positive if you observe new nystagmus after
how to manage BPPV
epley manoeuvre
what is cholesteatoma?
serious and rare complication of chronic otitis media and commonly occurs in younger patients
what causes cholesteatoma?
caused by abnormal accumulation of skin, squamous epithelium within the middle ear cleft and mastoid air cells
clinical features of cholesteatoma
presents foul smelling discharge, headache and otalgia
will present on examination of tympanic with an area of white in the attic behind the tympanic membrane
what complications occur from cholesteatoma
facial nerve palsy and CNS complications
what would you see with otoscopy on a patient with acute otitis media
red, yellow or cloudy tympanic membrane
bulging tympanic membrane
air-fluid level behind tympanic membrane
what does a normal tympanic membrane look like
slight translucency with a colour sometimes described as pearly-grey
describe otitis externa
inflammation of external auditory canal
can be categorised into acute <3weeks or chronic >3 months
aka swimmers ear
risk factors for otitis externa
swimming
humid air
young age
diabetes
trauma
symptoms of otitis externa
itch
tenderness
hearing loss
discharge
treatment of otitis externa
analgesia and topical therapies - topical abx
most common microbiological cause of otitis externa
pseudomonas aeruginosa
gram negative rod
management of persistent glue ear
2-6 weeks of amoxicillin
grommet insertion if that fails, bilateral, and persistent
management of persistent glue ear
2-6 weeks of amoxicillin
grommet insertion if that fails, bilateral, and persistent
mx mastoiditis
admission for IV abx and monitoring
Symptoms and signs of basal skull fracture
Head injury
Reduced consciousness
Battles sign = bruising of mastoid process
Raccoon eyes = bruising around eyes
Rhinorrhoea = CSF leaking from ear
Cranial nerve palsy
Bleeding from nose/ears
Haemotympanum - blood visible behind tympanic membrane
Classically affects one at between 30-60
vertigo, tinnitus with fluctuating hearing loss
episodic nature
Classically affects one at
Between 30-60
Characterised by attacks of sudden paroxysmal vertigo with associated deafness and tinnitus
Normally occur in clusters with periods of remission
Normal Webers test result
Patient can hear the sound equally in both ears
If patient had sensorineural hearing loss what would their Webers test result be
Sound will be louder in the normal ear
If patient had conductive hearing loss what would their Webers test result be
Sound will be louder in affected ear
Normal rinnes test result (rinnes positive)
When patient can hear the sound again when the tuning fork is hovered over their ear (air conduction)
Air conduction should be better
Abnormal rinnes test (rinnes negative)
When bone conduction is better than air conduction
So the sound is not heard after removing the tuning fork from the mastoid process
This suggest conductive hearing loss

Most common cause of neck lumps in children
Typically undetectable until the cyst swells in size commonly due to infection
Do not move on tongue protrusion nor auscultation or transilluminate
What is the Pathophysiology of tympanosclerosis
Associated with long term otitis media and grommet insertion
Result of calcium phosphate plaques leaving white patches on the tympanic membrane
What is otosclerosis
