nasal polyps Flashcards
(6 cards)
what are nasal polyps?
Benign lesions of the nasal mucosa or paranasal sinuses due to chronic
mucosal inflammation
what are the risk factors for nasal polyp formation?
- Chronic rhinosinusitis
- Cystic fibrosis (CF)
• Aspirin exacerbated respiratory disease
(AERD; aspirin or NSAID induced):
A triad of asthma, chronic sinusitis with polyps, and bronchospasm
what are the clinical features of nasal polyps?
- post nasal drip
- Bilateral nasal obstruction
- Frequently impaired olfactory function (from hyposmia to anosmia)
- Fever and severe facial pain are uncommon.
what is post nasal drip?
Abnormally increased nasal mucus secretion that drips down the back of the throat and can lead to coughing, a feeling of obstruction
in the throat, and throat clearing.
Causes include allergies, cold temperatures, viral or bacterial infections, dry air, and certain medications.
First-line treatment includes first-generation antihistamines (e.g., diphenhydramine)
what investigations can be done into nasal polyps?
- Nasal cytology for eosinophilia
- Evaluate for associated conditions (e.g., sweat chloride test for CF)
- Nasal endoscopy: bilateral grey polypoid mucosa hypertrophy
- CT: determines the exact location and extent of polyps; also useful to exclude other causes of nasal obstruction
how are nasal polyps managed?
Topical or systemic glucocorticoids
Resection of polyps if symptomatic despite medical therapy but recurrence is
common
