ENT Flashcards
define tonsilitis
inflammation of the palantine tonsils, suaully bilateral and can be viral or bacterial
bacterial causes of tonsilitis
group A beta haemoltic strep
staphylococci
H. influenzae
pneumococci
presentation of tonsilitis
few days of sore throat
referred otalgia, fever, generally unwell and dehydrated
may have difficutly eating and drinking
enlarged tonsils, muffled voice
when to refer tonsuilitis to ENT
unable to eat and drink
difficulty swalllowing salviva
signs of resp distress or airway compromise
glandular fever AKA
infectious mononucleosis
cause of glandular fever
epstein barr virus (EBV) and some CMV
complications of galndular fever
bacterial tonsilitis
hepatitis and splenic rupture
testing of glandular fever
infectious mononucleosis screen acutely
EBV serology or IgG testing
presentation of glandular fever
tonsilitis
already treated with course of antibiotics with minimal effect
amox + EBV = widespread rash (not allergic)
advise for those with glandular fever
avoid contact sports, alcohol and attend A+E if sudden onset abdo pain - hepatitis and splenic rupture
avoid kissing and sharing cutlery/gasses
when to refer glandular fever to ENT
- Unable to eat and drink
- Difficulty swallowing saliva
- Signs of respiratory distress or airway compromise (very rare!)
Quinsy AKA
peritonsillar abscess
what is qunisy
pus collects between tonsillar caosule and superior constrictor muscle as a complication of tonsilitis, usually unilateral
presentation of quinsy
few day history of bilateral sore throat which has significantly worsened unilaterally
severe odynophagia, fever, unwell, dehydrated, trismus, hot potato voice, spitting oiut saliva
when to refer quinsy to ENT
all suspected should be referred for needle aspiration or incision and drainage of pus
most drained and patient goes home same day with oral antibiotics
red flags of acute throat infections
severe sore throat:
- without evidence of tonsilitis/pharyngitis
- with hoarse/croaky voice, dysphagia and fever
- with neck swelling or neck stiffness (reduced range of movement)
severe trismus
stridor
what is supraglottisis and epiglottis
inflammation of the supraglottis and/or epiglottis
cause of supraglottis and epiglottisis
Haemophilus influenza type B
but reduced due to vaccinations
presentation of supra/epiglotttis
worsening sore throat
uanble to eat and drink often drooling saliva
hoarse or croaky and possibly stridor
children = tripod for airflow
treatment of supra/epiglottisis
adrenaline nebulisers
IV steroids
broad spec antibiotics (IV ceftriaxone)
what are deep neck space infections
collection of pus within potential spaces of the neck formed by investing layer of cervical fascia
cause of deep neck space infectioms
mostly dental origin
can progress from tonsils/quinsies or infected epidermoid, branchial or thyroglossal cysts
presentation of deep neck space infections
toothache, sore throat or prev neck swelling (cyst) now progressed to neck pain
redyuced neck movements, localised or widespread nbeck swelling (fluctuant or firm) possibly with overlying cellulitis
management of deep neck space infecdtionns
FNE and liekly CT of the neck, broad spectrum antibiotics and possbily surgical drainage and debridement
who gets epistaxis
<10 yo
45-65 yo
why male predomination of epistaxis in < 49 yo
protective effect of oestrogen
seasonal factors affecting epsitaxis?
incidence of upper respiratory infections
allergic rhinitis
mucosal changes associated with fluctuations in temp and humidity
types of epistaxis
anterior = from kiesselbatches plexus or littles area –> slef limited, most common, managed in primary setting, mucosal truama or irritation
posterior - postlateral bracnhes of sphenpalantine artery but also arise from branches of the carotid, significant haemorrhage
risk factors of epistaxis
trauma inflammatory - sinusitis or rhinitis drugs - apsirin, clopidogrel, anticoagulant and cocaine neoplasm systemic disease- granulomatosis with polyangitis, CPA, sarcoidosis hereditary bleeding disorder low moisture contnet of air intranasal drug use hypertension
management of epsitaxis
ABCDE approach
local compression for 20min and ice packs
examine nose - rule out septal haematoma and reduce nasal fracture
nasal cautery
nasal pakcing
surgical option s- intervential radiologist angiogrpahic embolization
house-brackmann clasification
facial nerve weakness classficiation of facial nerve palsy
I for normal, VI for no movement
House-Brackmann Grading System I
normal facial function
House-Brackmann Grading System II
- Slight weakness, normal symmetry and tone
- Complete eye closure and forehead movement with effort
- Mouth slightly weak
House-Brackmann Grading System III
- Small difference between 2 sides at rest
- Complete eye closure with effort, slight to moderate forehead movement
- Mouth slightly weak
House-Brackmann Grading System IV
- Obvious weakness and disfiguring asymmetry
- No forehead movement
- Incomplete eye closure
- Mouth asymmetrical
House-Brackmann Grading System V
- Only barely perceptible motion, asymmetrical at rest
- No forehead movement
- Incomplete eye closure
- Mouth asymmetrical
House-Brackmann Grading System VI
• No movement / Total paralysis
forehead involved
forehead sparred (contralateral supply)
LMN lesions
UMN lesions
idiopathic - bells palsy (most)
trauma - temporal bone or facial wound
infection - ear infections, lymes disease, viral infection
tumour - parotid malignanc iatrogenic - parotid or ear surgery autoimmune - sarcoidosis neurological conditions congenital - CHARGE, mobius syndrome, melkersson-rosenthal syndrome, birth trauma/forceps
causes of FN palsy
neurological conditions causing FN palsy
MS
CVA (stroke)
Myasthenia gravis
Guillain Barre
investigations for FN palsy
full facial nerve examination and grade weakness
classify into UMN and LMN
assess hearing of ipsilateral ear and mastoid + tuning fork
cranial nerve examination
examination of neck and parotid to exclude parotid tumour
examination of oral cavity to assess palatal weakness etc
schrimers test for lacrimation - what does it suggest in FN lesion?
abnormal lesion suggests lesion affecting the geniculate ganglion
stapedial reflex - what does it suggest in FN lesion?
abnormal suggests lesion proximal nerve to stapedius
taste testing - what does it suggest in FN lesion?
clinically or electrogustometry and salivary flow testing
- if abnoramla suggests lesion proximal to the root of chorda tympani
treatment of FN palsy
- education
- blood tests
- bells palsy
- ramsay hunt syndrome
education - eye protection since corneal drying can lead to ulceration and then blindness
manage obvious cause
blood tests - lymes disease if indicated in history
if bells palsy - 7-10day reducing dose of corticosteroids
ramsay hunt syndrome (VZV) - course of aciclovir and reducing corticosteroids
follow up in 3-4 weeks - lakc of recover, investigate for neoplasia via MRI
prognosis of bells palsy
full recovery in 3-4 months
advise for bells pasly
keep affected eye lubricated
tape eye closed at bedtime if needed
wear sunglasses outdoors to protect eye
swimming and dusty environments should be avoided
surgery for protection - tarsorraphy +/- gold weight implant to aid eyelid closure
eye irritation pain or vsion changes - seek immediate medical advice
if facial weakness or paralysis affects eating
suggest using straw for liquids and advice soft foods
exercise to rehab facial muscles
things to do in first 6 weeks of bells palsy
massage face with strokes towards ear
facial exercises to achieve symmetrical movements in front of mirror and use fingers to assist
perform slowly and gently
conductive deafness
failure of the conversion of sound waves into movements by the ear drum and ossicles of the middle ear
sensorineural deafness - congenital or acquired
problem of the inner ear or of the nerve that carries the signal from the inner ear to the hearing centres of the brain
weber test results
forehead
unilateral conudctive loss = lateralisation to the affected side
unilateral sensorineural loss = lateralisation to normal or better hearing side
rinnes test results
air conduction and bone conduction
normal = AC >BC - (pt can hear fork at ear)
conductive loss = BC>AC (pt will not hear fork at ear)
conductive hearing loss causes
wax/foreign body/polyps
otitis externa
otitis media
perforation
sensorineural hearing loss causes
