ENT Flashcards
What is tonsillitis
Inflammation of the tonsils (mainly palatine)
Usually due to viral infection
Bacterial causes: group A strep, strep pneumoniae, haemophilus influenzae, staphylococcus aureus
Peak ages: 5-10, 15-20
Which lymphoid tissues make up Waldeyer’s tonsillar ring
Adenoids
Tubal tonsils
Palatine tonsils
Lingual tonsils
How might a patient with tonsillitis present
Fever
Sore throat
Pain swallowing
Non-specific symptoms in children: fever, poor oral intake, headaches, vomiting, abdominal pain
See red, enlarged tonsils (may have white patches of exudate)
What is the centor criteria
Estimates probability that tonsillitis is due to bacterial infection (will need antibiotics)
Score 3+ is significant
Fever > 38
Tonsillar exudate
Absent cough
Tender anterior cervical lymph nodes
What is the FeverPAIN score
Estimates probability that tonsillitis is due to bacterial infection (will need antibiotics)
Score 4+ is significant
Fever during previous 24 hours
Pus on tonsils
Attended within 3 days of symptom onset
Inflamed tonsils
No cough or coryza
What is the management for tonsillitis
Educate
Safety netting (return if not settled in 3 days, fever > 38.3)
Simple analgesia
Consider antibiotics (penicillin V for 10 days, or clarithromycin)
Consider delayed prescription
Admit if: immunocompromised, systemically unwell, dehydrated, stridor, respiratory distress, peritonsillar abscess, cellulitis
What are the complications of tonsillitis
Chronic tonsillitis
Peritonsillar abscess (Quinsy)
Otitis media
Scarlet fever
Rheumatic fever
Post-strep glomerulonephritis
Post-strep reactive arthritis
What is Quinsy
Aka peritonsillar abscess
Usually a complication of tonsillitis
Due to bacterial infection: group A strep, staph aureus, haemophilus influenzae
How might a patient with Quinsy present
Tonsillitis symptoms
Trismus (unable to open mouth)
Changes in voice
Swelling and erythema in area beside tonsils
What is the management for Quinsy
Refer to hospital urgently
Need incision and drainage
Antibiotics before and after surgery
Consider steroids (dexamethasone)
When should tonsillectomy be performed for tonsillitis
7+ in 1 year
5 per year for 2 years
3 per year for 3 years
Other than for tonsillitis, when should tonsillectomy be performed
2+ episodes of tonsillar abscess
Enlarged tonsils causing difficulty breathing or swallowing
What are the complications of tonsillectomy
Pain
Sore throat
Damage to teeth
Infection
Post-tonsillar bleeding (up to 2 weeks after surgery, can be life threatening due to aspiration of blood, consider intubation if severe)
Risk of anaesthetic
What is otitis media
Inner ear infection
Bacteria enter from back of throat (through eustachian tube) following URTI
Common bacteria: haemophilus influenzae, staph aureus
How might otitis media present
Ear pain
Reduced hearing
General URTI symptoms
Balance issues/vertigo (if vestibular system affected)
Discharge (if tympanic membrane ruptured)
Infants: fever, vomiting, irritability, lethargy, poor feeding
What is the management for otitis media
Consider admission (< 3 months temp > 38, 3-6 months temp > 39)
Usually resolves without antibiotics
Simple analgesia
Immediate antibiotic prescription: significant comorbidities, < 2 with bilateral infection, discharge
Delayed prescription
Amoxicillin for 5 days
What are the complications of otitis media
Otitis media with effusion
Hearing loss
Perforated eardrum
Recurrent infection
Mastoiditis
Abscess
