nasal polyps Flashcards
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
