Nasal Polyps
Nasal polyps are soft oedematous inflammatory growths that usually occur bilaterally and cause nasal obstruction and reduced smell; a unilateral or bloody/atypical mass is a different problem until ENT assessment excludes tumour or another local lesion.
Definition
Nasal polyps are soft, oedematous outgrowths of inflamed sinonasal mucosa that prolapse into the nasal cavity. They are usually bilateral and form part of chronic rhinosinusitis with nasal polyps; a unilateral mass is investigated as a separate condition until a localised lesion or tumour has been excluded.
First principles
Bilateral disease usually reflects diffuse sinonasal inflammation
Inflamed sinonasal mucosa can become oedematous and prolapse into the nasal cavity as pale, soft polyps. Bilateral disease is the usual inflammatory pattern and often coexists with chronic rhinosinusitis, asthma or sensitivity to aspirin/other NSAIDs.
