Rhinitis & Sinusitis Flashcards
What to ask in nasal history
- Nasal blockage • bilateral
- unilateral
- Discharge • bilateral
- unilateral
- Sense of smell • Facial pain
- Bleeding
- Itch
- Sneezing
Describe the history of the nasal septum
Lined with ciliated psuedostratified columnar epithelium.
Blood supply to the nose
Blood supply is an anastamosis between internal and external carotid artery
• Very rich blood supply!
Anterior ethmoid
Posterior ethmoid
sphenopalatine
Greater palatine
Superior labial (from facial )
Describe the location of the Paranasal sinuses
• Infmeatus • nasolacrimalduct • Middle meatus • frontalsinus,maxillarysinusand anterior ethmoid sinuses • Superiormeatus • posterior ethmoid sinuses
Management of Epistaxis
- ABC approach
- Oxygen/IV access/Bloods
- Pressure/ice
- Cautery
- Packing - Anterior Nasal pack • Posterior Nasal Pack
- Anterior/posterior
- Surgery
- Septoplasty
- Cautery
- SPA ligation
Nasal Symptoms: Red Flags
- Unilateral Symptoms BEWARE
* Unilateral Masses ALWAYS malignant until proven otherwise • 10% H&N malignancy
Inflammatory Nasal Polyposis (benign)
Benign nasal polyps are always bilateral, asensate and tend to be pale. Association with asthma and salicilate sensitivity
Management of Benign nasal Polyps
- Nasal steroid
- Step ladder approach • Topical spray
- Topical drops
- PO
- Surgery
Antrochoanal Polyp management
- Benign unilateral nasal mass • Smooth
- Come on after URTI
- Need removal
- Differential includes inverting papilloma/Ca • Need biopsy/excision
- Propensity to recur
Angiofibroma presentation
Usually present with unilateral epistaxis/blockage in teenage boy
Nasal Carcinoma/Ethmoid Ca risk factors
Risk factors • Smoking
• Age
• Woodworkers • Smokers
• Textile workers
Nasal Carcinoma/Ethmoid Ca symptoms
- Unilateral nasal blockage • Doublevision
- Cheek swelling
- Altered bite
- Loose teeth
Allergic Rhinitis diagnostic criteria
• Congestion • Rhinorrhoea • Itching
• Sneezing
Presentation
• 2 or more of the above on most days for >1hour is diagnostic • Intermittent/mod/severe
Pathophysiology of Allergic Rhinitis
- Type 1 Hypersensitivity
- IgE mediated antigen specific
- TH2 response (TH1 cell mediated)
- One airway one disease
- 80% with asthma have AR
- 10-40% with AR have asthma
- Early treatment of allergic rhinitis may influence asthma.
Management of Allergic Rhinitis
- Allergen avoidance
- Nasal steroid
- Antihistamine
- Oral steroid
- Ipratropium bromide
