structure results from prolapsed lining of ethmoid sinus
Aetiology
1
bernouilli phenomenon
If there is constriction the pressure will drop result in
prolapse of mucosa
2
polysaccride changes in ground substance
3
vasamotor imbalance when patient is not atopic
4
infection
5
allergy 90% or more of polyps have eosinophil and threr is
association with asthema,and the nasal finding mimic
allergy(rhinorrhea,sneezing &nasal obstruction

intranasal ethmoidectomy which done
endoscopically
3
external ethmoidectomy
