Q

Nasal Polyps: Investigation

A

Clinical diagnosis based on examination.

Nasal endoscopy: Useful if polyps are not visualized via anterior rhinoscopy.
CT scan of the sinuses: Indicated if polyps are unilateral (requires a 2-week referral for evaluation).

Q

Allergic Rhinitis: Aetiology

A

Allergic rhinitis is an IgE-mediated inflammatory disorder of the nasal mucosa.

When sensitized to allergens, the nasal mucosa releases histamines, causing typical symptoms of allergic rhinitis.

Q

Allergic Rhinitis: Management

A

General Measures-
Nasal irrigation with saline
Allergen avoidance

Mild Persistent or Intermittent Symptoms-
Intranasal corticosteroids&raquo_space; anti inflammatory and immunosuppressive
Intranasal or non-sedating oral antihistamines&raquo_space; reduce inflammation

Moderate-Severe Persistent Symptoms or Unresponsive Cases-
Daily intranasal corticosteroid with or without intranasal antihistamine&raquo_space; full effectiveness up to 2 weeks
For eye symptoms: Antihistamine or chromone eye drops&raquo_space; sodium cromoglycate

Q

Allergic Rhinitis: Further Management

A

Consider stepping-up treatment-

Nasal congestion- add intranasal decongestant x5-7 days
Rhinorrhoea- add intranasal anticholinergic (ipratropium bromide)&raquo_space; blocks acetylcholine reducing secretion from nasal passage.
Nasal itching, sneezing- add regular oral antihistamine or combination intranasal antihistamine with corticosteroid (Dymista)
Concurrent asthma- add leukotriene receptor antagonist (montelukast)

Severe symptoms affecting QOL-
Short-course oral corticosteroid (prednisolone)

Refer for immunotherapy-
Objective confirmation of IgE sensitivity to predominantly one allergen
Expose patient to increasing amounts of allergen over several weeks to induce tolerance

Q

Acute Sinusitis: Definition

A

Acute sinusitis, commonly known as a sinus infection.
Symptomatic inflammation of the paranasal sinuses and nasal cavity lasting less than 12 weeks.

18
Q

Acute Sinusitis: Aetiology

A

Often follows a viral upper respiratory tract infection (URTI)

Bacterial infection occurs in 0.5-2% of cases, commonly caused by:
» Streptococcus pneumoniae
» Haemophilus influenzae
» Moraxella catarrhalis

19
Q

Acute Sinusitis: Risk Factors

A

Allergy rhinitis
Asthma
Smoking
Anatomical variations&raquo_space; deviated nasal septum, nasal polyps

20
Q

Acute Sinusitis: Symptoms

A

Upper respiratory tract infection (URTI) symptoms&raquo_space; sore throat, cough, malaise
Nasal blockage or congestion
Nasal discharge
Facial pain or pressure
Reduction or loss of smell

21
Q

Acute Sinusitis: Signs

A

Maxillofacial sinus swelling, erythema, or tenderness
Discoloured or purulent nasal discharge
Oedematous nasal mucosa&raquo_space; nasal mucosa becomes inflamed&raquo_space; oedema
Fever

22
Q

Acute Sinusitis: Investigation

A

Diagnose using symptoms-

Acute viral (common cold)&raquo_space; symptoms less than 10 days

Post-viral acute sinusitis&raquo_space; symptoms more than 10 days or worsening symptoms after 5 days

Acute bacterial sinusitis&raquo_space; at least 3 present-
Symptoms more than 10 days
Discoloured or purulent nasal discharge
Severe localized pain
Fever
Double sickening

23
Q

Acute Sinusitis: Treatment

A

Acute:
Symptoms less than 10 days: no antibiotics, paracetamol, nasal decongestant, saline spray

Symptoms more than 10 days: high dose nasal corticosteroid for 14 days
Consider back-up antibiotic prescription -evidence shows little effects on symptoms
» phenoxymethylpenicillin
» doxycycline if allergic to penicillin (not for pregnant women)

Chronic:
Supportive care, control underlying condition, stop smoking, avoid allergic triggers, nasal saline irrigation, intranasal corticosteroid for 3 months

24
Q

Chronic Sinusitis: Definition

A

Symptomatic inflammation of the paranasal sinuses lasting for 12 weeks or more.

25
Chronic Sinusitis: Aetiology
Inflammatory and typically multifactorial Bacterial aetiology different from acute: >> Staphylococcus aureus >> Enterobacteriaceae >> Pseudomonas
26
Chronic Sinusitis: Risk Factors
Allergic rhinitis Asthma >> atopy Smoking Immunocompromised Ciliary impairment >> ciliary in sinuses cant clear pathogens >> cystic fibrosis Aspirin sensitivity >> associated with nasal polyp formation
27
Chronic Sinusitis: Symptoms
SAME AS ACUTE >> LONG-TERM AND CHRONIC Upper respiratory tract infection (URTI) symptoms >> sore throat, cough, malaise Nasal blockage or congestion Nasal discharge Facial pain or pressure Reduction or loss of smell
28
Chronic Sinusitis: Signs
SAME AS ACUTE >> LONG-TERM AND CHRONIC Fever Maxillofacial sinus swelling, erythema, or tenderness Discoloured or purulent nasal discharge Oedematous nasal mucosa >> nasal mucosa becomes inflamed >> oedema
29
Chronic Sinusitis: Investigation
Clinical diagnosis CT scan of sinuses >> only if ENT orders
30
Chronic Sinusitis: Management
Supportive care- Control underlying condition Stop smoking, avoid allergic triggers, good dental hygiene Nasal saline irrigation Intranasal corticosteroid >> x3 months ENT referral if- Considering antibiotic therapy Persistent symptoms after 3 months Immunocompromised
31
Epistaxis: Definition
Nosebleed 80-95% in anterior nasal septum >> Kisselbach's Plexus
32
Epistaxis: Aetiology
Trauma >> nose picking, fracture, ulcers Inflammations Topical drugs >> cocaine, decongestants, corticosteroids Systemic drugs >> anticoagulants Tumours Nasal oxygen therapy >> hospital oxygen not well humidified >> dries out nose and makes tissue delicate. Clotting disorders Excessive alcohol consumption >> affect on liver >> clotting Environmental factors
33
Epistaxis: Investigation
Anterior rhinoscopy >> visualise bleed FBC >> check coagulation factors Suspect posterior bleed if- Unable to visualise bleed Bleeding going down throat >> profuse bleeding Bilateral bleeding
34
Epistaxis: Management
Anterior bleed- First aid >> sit upright, lean forward, pinch nose. If bleeding stops >> prescribe topical antiseptic, avoid trauma to nose. If bleeding doesn’t stop >> nasal cautery, nasal packing. Posterior bleed- Refer to ENT
35
Nasal Fracture: Definition
Broken nose
36
Nasal Fracture: Symptoms and Signs
Nasal deformity Nasal obstruction Painful palpation Swelling and discolouration Epistaxis
37
Nasal Fracture: Investigation
Clinical and visual Typically no X-ray needed
38
Nasal Fracture: Management
Refer to Manipulation Under Anasthesia (MUA) >> to be seen within 7 days Refer immediately if- Gross displacement Compound Uncontrolled bleed CSF rhinorrhoea Septal haematoma >> collection of blood around fracture >> swelling and tender
39
Nasal Foreign Body: Definition
Obstruction
40
Nasal Foreign Body: Symptoms and Signs

41
Nasal Foreign Body: Investigation
Clinical and Visual
42
Nasal Foreign Body: Management
Topical vasoconstrictors to reduce swelling Mother’s kiss >> parent hold nostril and blows into child’s mouth to push out FB Crocodile forceps Balloon catheter >> pass behind FB, inflate and withdraw Suction catheter Magnet
