Q

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

A
  • 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

Q

How do we classifiy rhinosinusitis?

A

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

Q

How would you treat rhinosinusitis?

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

Or sinus surgery

17
Q

Explain the aetiology of nasal polyps?

A

-Unknown
-Chronic inflammation
-Autonomic nervous system dysfunction
-Genetic predisposition
CF
AFS- allergic fungal sinusitis
Chrug-strauss syndrome (vasculitis of people with a history of airway allergic hypersensitivity)
-Associated with Allergic conditions
20-50% have asthma
Allergic rhinitis
Aspirin intolerance
Alcohol intolerance

18
Q

What is churg-strauss

A

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

19
Q

How would we investigate a case of nasal polyps?

A
  • 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
Q

How do we treat nasal polyps?

A
  • Oral or nasal Steroids
  • Immunotherapy for allergic rhinitis or aspirin hypersensitive patients
  • Surgery (either a nasal polypectomy or Functional Endoscopic Sinus Surgery - FEST)
21
Q

What causes Epistaxis?

A
  • Infection
  • Idiopathic
  • Trauma/Iatrogenic
  • Allergy
  • Vascular (Atherosclerosis/hypertension)
  • Blood Dyscrasias
  • Atrophic Rhinitis
  • Tumor
  • Nasal Defect
  • Hereditary Hemorrhagic Telangiectasia
22
Q

What could cause blood dyscrasias?

A
  • Drugs
  • Disease
  • Alcoholism
23
Q

What is hereditary Hemorrhagic Telengiectasia?

A

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

24
Q

How would we manage Epistaxis?

A
  • Vital signs i.e. do they need IV transfusions etc
  • Physical exam incl. rhinoscopy
  • Labs
  • current medications
  • Nasal Packs
  • Surgery
25
Q

What types of nasal packs are there?

A
  • Ant Nasal Packs
  • Post Nasal Pack
  • Ant/Post Pack, uses balloons
26
Q

What kind of surgery is there for epistaxis?

A

Arterial Ligation

  • Sphenopalatine
  • Internal Maxillary
  • Ant/post ethmoids
  • ECA

Laser Ablation + Septodermoplasty

Embolisation (blocking abnormal vessels)

27
Q

How do we treat Hereditary Haemorrhagic Telangectasia?

A
  • Laser Coagulation
  • Septodermoplasty
  • Young’s Procedure
28
Q

What is youngs procedure?

A

Involves closing the nasal cavity with mucocutaneous flaps.

29
Q

How would a patient present with an angiofibroma?

A

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

30
Q

How would you treat an angiofibroma?

A

Pre-op Embolisation

Surgery

31
Q

Why would you be worried about a hearing loss and epistaxis together?

A

Together they’re a red flag symptom
