Rhinology Flashcards
What occupations are at risk of nasal disorders? [1]
Woodworkers
What bloods are appropriate for nasal disorders? [5]
- FBC
- ESR
- Radioallergosorbent blood Test (RAST)
- ANCA (Anti-neutrophil cytoplasmic antibody) for vasculitis
- ACE (angiotensin Converting Enzyme)
Why would you use an ACE test for nasal disorders? [2]
Rhinosinusitis could be related to TB [1] or Sarcoid [1] which would show up on an Angiotensin Converting Enzyme test.
What is the RAST test [2]
What is its clinical significance [1]
Radioallergosorbent Test [1]
It tests the blood for specific IgE levels. [1]
Can identify allergic rhinosinusitis [1]
Define Choanal Atresia? [3]
How does it present?
Congenital [1] blockage of the posterior nasal aperture [1] by either a membrane or bone. [1]
Bilateral; tends to show up in babies with trouble feeding. [1]
If unilateral may not show up till later [1]
Whats the relevance of aspirin sensitivity?
Related to lots of atopic disease such as aspirin sensitive asthma or rhinitis
An URTI infection can causes periorbital swelling, how would we handle this situation? [5]
- Emergency ENT referral
- Ophthalmology Opinion to assess colour vision, its the first to go when the optic nerve is damaged
- Urgent CT to show up abscess
- IV antibiotics and Steroids
- Emergency Surgery
What is Pott’s puffy tumour?
Clinical features [4]
Its a complication of sinusitis, basically a subperiosteal abscess. [1] Sinusitis Fever Frontal headache Central forehead swelling
How do we treat Pott’s Puffy Tumor? [3]
Frontal Sinus Surgery or Endoscopic Sinus Surgery (ESS) followed by Abx
What is mucocele? [2]
Management [1]
A benign cyst lesion of a minor salivary gland [1] containing mucous [1] . Needs to be removed with endocopic sinus surgery
What would you see on sinusitis CT or MRI [2]
- Sinus opacification
- Or a visible air/fluid level
- and/or mucosal thickening
What is rhino sinusitis? [1]
How do we classifiy rhinosinusitis? [3] Define each classification
Rhinosinusitis is inflammation in nose and paranasal sinuses.
Into Acute, Recurrent Acute, Chronic and Acute exacerbation of chronic.
Acute = <12 wks & Symptoms resolve completely
Recurrent Acute = 1-4 episodes a yr with completely recovery and 8wks symptom free between episodes.
Chronic = >12wks with persistant inflammatory changes on imaging for >4wks
Acute Exacerbations of Chronic: = Worsening or new symptoms with the acute ones resolving completely but not the chronic ones
What microorganisms cause rhinosinusitis? [3]
Strep Pneumonia -31%
Haemophilus Influenzae - 21%
Both - 5%
What symptoms come with rhinosinusitis?
Main symptoms [2]
Associated symptoms [4]
Main symptoms:
- Nasal congestion
- Nasal discharge
Also possible to get:
- Facial pain/pressure
- Hyposmia/Anosmia
- Purulent postnasal drain
- Cough
How would you treat rhinosinusitis? [4]
- Topical CCS, nasal douching
- B-lactams (e.g. penicillins or cephalosporins)
- Macrolides (E.g. Erythromycin/Clarythromicin)
Or sinus surgery
