1

What occupations are at risk of nasal disorders?

Woodworkers

2

What would a nasal endoscopy see?

The middle turbinate and back of the nose
Unlikely to see the sup turbinate

3

What bloods are appropriate for nasal disorders?

- FBC
- ESR
- Radioallergosorbent blood Test (RAST)
- ANCA (Anti-neutrophil cytoplasmic antibody) for vasculitis
- ACE (angiotensin Converting Enzyme)

4

Why would you use an ACE test for nasal disorders?

Rhinosinusitis could be related to TB or Sarcoid which would show up on an Angiotensin Converting Enzyme test.

5

What does a RAST test show?

Radioallergosorbent Test
It tests the blood for specific IgE levels.

6

Define Choanal Atresia?

Congenital Blockage of the posterior nasal aperture by either a membrane or bone.

Bilateral tends to show up in babies with trouble feeding.
If unilateral may not show up till later

7

Whats the relevance of aspirin sensitivity?

Related to lots of atopic disease such as aspirin sensitive asthma or rhinitis

8

An URTI infection can causes periorbital swelling, how would we handle this situation?

- 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

9

What is Pott's puffy tumour?

Its a complication of sinusitis, basically a subperiosteal abscess.
So the patient appears with sinusitis symptoms + fever, frontal headache and central forehead swelling.

10

How do we treat Pott's Puffy Tumor?

Frontal Sinus Surgery or Endoscopic Sinus Surgery (ESS) followed by Abx

11

What is mucocele?

A benign cyst lesion of a minor salivary gland containing mucous. Needs to be removed with endocopic sinus surgery

12

What would you see on sinusitis CT or MRI

- Sinus opacification
- Or a visible air/fluid level
- and/or mucosal thickening

13

How do we classifiy rhinosinusitis?

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

14

What microorganisms cause rhinosinusitis?

Strep Pneumonia -31%
Haemophilus Influenzae - 21%
Both - 5%

15

What symptoms come with rhinosinusitis?

- Facial pain/pressure
- Hyposmia/Anosmia
- Congestion/Obstruction
- Purulent postnasal drain
- Olfactory Disturbance
- Cough

Also possible to get:
- Headache
- Fever
- Fatigue
- Halitosis
- Dental Pain

16

How would you treat rhinosinusitis?

- B-lactams (e.g. penicillins or cephalosporins)
- Macrolides (E.g. Erythromycin/Clarithromicin)

Or sinus surgery

17

Explain the aetiology of nasal polyps?

Its unknown although its often associated with allergic conditions such as rhinitis, asthma, aspirin sensitivity or alcohol intolerance
Also with CF and churg-strauss

18

What is churg-strauss

An allergic (i.e. autoimmune) granulomatosis causing vasculitis of people with a history of airway allergic hypersensitivity.

19

How would we investigate a case of nasal polyps?

- Sweat test in case of CF
- RAST/allergic skin tests for atopic disease
- Coronal CT/MRI
- Flexible or Rigid Nasoendoscopy

Can also do a nasal smear for eosinophils (allergic component) or neutrophils (chronic sinusitis)

20

How do we treat nasal polyps?

- Oral or nasal Steroids
- Immunotherapy for allergic rhinitis or aspirin hypersensitive patients
- Surgery (either a nasal polypectomy or Functional Endoscopic Sinus Surgery - FEST)

21

What causes Epistaxis?

- Infection
- Idiopathic
- Trauma/Iatrogenic
- Allergy
- Vascular (Atherosclerosis/hypertension)
- Blood Dyscrasias
- Atrophic Rhinitis
- Tumor
- Nasal Defect
- Hereditary Hemorrhagic Telangiectasia

22

What could cause blood dyscrasias?

- Drugs
- Disease
- Alcoholism

23

What is hereditary Hemorrhagic Telengiectasia?

Autosomal Dominant condition leading to abnormal blood vessel formation.
One manifestation is Epistaxis

24

How would we manage Epistaxis?

- Vital signs i.e. do they need IV transfusions etc
- Physical exam incl. rhinoscopy
- Labs
- current medications

- Nasal Packs
- Surgery

25

What types of nasal packs are there?

- Ant Nasal Packs
- Post Nasal Pack
- Ant/Post Pack, uses balloons

26

What kind of surgery is there for epistaxis?

Arterial Ligation
- Sphenopalatine
- Internal Maxillary
- Ant/post ethmoids
- ECA

Laser Ablation + Septodermoplasty

Embolisation (blocking abnormal vessels)

27

How do we treat Hereditary Haemorrhagic Telangectasia?

- Laser Coagulation
- Septodermoplasty
- Young's Procedure

28

What is youngs procedure?

Involves closing the nasal cavity with mucocutaneous flaps.

29

How would a patient present with an angiofibroma?

Profuse one sided epistaxis.
Exclusively male and mainly in teens or twenties.
Don't Biopsy as its a vascular tumor and theyll bleed.

30

How would you treat an angiofibroma?

Pre-op Embolisation
Surgery
