11 - ENT Flashcards
What bacteria most commonly cause otitis media and what are some risk factors for developing this?
Usually preceded by viral URTI
Bacteria: Haemophilus Influenza, Strep Pneumonia, Moraxhella Catarrhalis
Risks: passive smoking, formula fed, craniofacial abnormalities, attend nursery
How does acute otitis media present in children?
Children will often have history of URTI
- Infant: fever, vomiting, irritability, lethargy, poor feeding
- Child: ear pain, reduced hearing, fever, cough, coryza symptoms
How does AOM present on examination?
Always check the ears and throat of unwell children
- Bulging red TM
- May be yellow or cloudy
- Loss of light reflex
How is uncomplicated AOM managed in children?
Most will self-resolve within 3 days
- Ibuprofen/Paracetamol: For fever and pain relief. Most cases will self-resolve within 3 days without antibiotics
- Antibiotics: If indicated give Amoxicillin for 5-7 days or Erythromycin. Give delayed until 3 days of symptoms
- Safety Net: advice to parents on when to seek further medical attention
What is the criteria for antibiotics in AOM?

How is chronic supportive otitis media managed in children?
Perforation - complication of AOM
- Refer to ENT
- Antibiotics, topical corticosteroids and intensive aural cleaning
What bacteria cause OE and how is otitis externa in children managed?
Always need to rule out ottorhea from an otitis media causing the otitis externa
- Clean ear: If cannot visualise TM. Use micro suction, dry swabbing
- Topical antibacterial: Acetic acid 2% with or without steroid for 1 week
- Paracetamol/Ibuprofen: for pain
- Safety net: avoid getting wet, come back if not resolving
Why are topical antibacterials only used for a short period of time in OE?
Can lead to chronic OE caused by a fungal infection
Use clotrimazole
What are common causes of hearing loss in children?
Congenital or Acquired
Children with deafness often present on the NHSP. Other children may present with speech and language or behaviour difficulties. How is hearing loss in children managed?
MDT
- Speech and language therapy
- Educational psychology
- ENT specialist
- Hearing aids for children who retain some hearing
- Sign language
What is the pathophysiology of mastoiditis and some risk factors for this?
Complication of AOM
- Mastoid air cells in temporal bone and communicate with middle ear via small canal
- Infection can spread from the middle ear into the mastoid air cells causing infection of the bone of the mastoid air cells, causing necrosis and subperiosteal abscess
How is mastoiditis diagnosed and how does it present?
Diagnose with CT WITH CONTRAST

- Pinch the soft part of the nose and hold for at least 15 minutes
- Put ice pack on neck
Primary care/ A&E management
- If any bleeding points identified, obtain verbal consent from parent for nasal cautery with silver nitrate. Do not cauterise both sides of the septum in the same episode.
- If bleeding continues, call ENT who will consider placing an anterior or a posterior nasal pack
- In recurrent cases, a full blood count and clotting profile should be checked

- Fever
- Sore throat
- Painful swallowing/poor oral intake
- Vomiting
- Abdominal pain
- Headache
Examination: red, inflamed and enlarged tonsils, with or without exudates
Always examine the ears to visualise TM and check for lymphadenopathy
What is the FeverPAIN score and how do you interpret the results?
Work out likelihood of infection being due to Streptococcus
Score of 4 or more warrants antibiotics
What is the Centor Score and how do you interpret it?
Estimate the probability that tonsillitis is due to a bacteria infection, and will benefit from antibiotics
Score of 3 or more give antibiotics
Tender lymphadenopathy
How is tonsillar size graded?
Based on how much space they take up in oropharynx
Enlarged tonsils could be due to recurrent tonsillitis leading to scarring, doesn’t mean it is tonsillitis
How is tonsillitis in children managed?
- Exclude other serious pathology, e.g meningitis, epiglottitis and quinsy
- Calculate FeverPAIN and Centor score
- Educate parents with likely viral tonsillitis, and give safety net advice to return if the pain has not settled after 3 days or the fever rises above 38.3ºC. May consider delayed prescription
- If Centor ≥ 3 or the FeverPAIN score is ≥ 4. or immunocompromised or history of rheumatic fever then prescribe antibiotics
When do children qualify for a tonsillectomy according to SIGN guidelines?
- 2 episodes of Quinsy
- Recurrent febrile convulsions secondary to episodes of tonsillitis

How is post tonsillectomy bleeding managed in children?
(important)
Management:
- Call ENT registrar
- Get IV access

-
Lateral Neck X-Ray
1) Thumb-Print Sign (swollen epiglottis) (5)
2) Thickened aryepiglottic folds
3) Increased opacity of the larynx and vocal cords
X-Rays can help rule out epiglottitis if a normal epiglottis is visualised, but should not waste time in a critical situation
How is epiglottis managed?
- Secure the Airway: escalate to senior ENT and anaesthetist
- Oxygen: Parent can hold mask near child’s face
- Nebulised Adrenaline

Most common cause of stridor in infants
Usually presents at 4 weeks and resolves by 2 years
How does laryngomalacia present?
- High-pitched inspiratory stridor worse on lying flat or on exertion
- Normal cry
How is laryngomalacia managed?
99% of cases resolve over time
Mild: parental reassurance that will resolve by 12-16 months, may worsen at 6 months or during URTI
Severe: e.g feeding difficulties, faltering growth, respiratory distress and apnoeas. Endoscopic aryepiglottoplasty aka supraglottoplasty
Life-Threatening: Respiratory distress usually exacerbated by URTI, SEE IMAGE

- Significant cervical lymphadenopathy
- Abdominal tenderness & splenomegaly
- Hepatomegaly
- Palatal petechiae
What antibiotic should not be given in glandular fever and why?
Ampicillin/Amoxicillin as a maculopapular, pruritic rash develops
What are red flags for foreign bodies?
What investigations are done for a ingested/inhaled foreign body?
- Plain film chest radiograph (assess for the foreign body, if radio-opaque, the presence of surgical emphysema, any widening of retropharyngeal tissue or loss of cervical lordosis)
How are ingested/inhaled foreign bodies removed?
- If the FB is visualised in the oropharynx: Magill forceps
- Otherwise, endoscopy under GA
