The origin of this disease is still unknown. Infection is not
normally thought to be part of the aetiology in the majority
of cases, but patients with nasal polyps are more prone to
problems with chronic infective rhino-sinusitis (see below).
In addition, some patients with chronic sinusitis can develop
an inflammatory hyperplasia of the nasal mucosa. This leads
to the development of localized nasal polyps, which will
originate in the area of the uncinate process and the middle
meatus. Simple inflammatory nasal polyps present
with nasal obstruction and hyposmia as the main symptoms,
with little accompanying pain. Treatment is predominantly
surgical although steroids used both topically or systemically
may have a role. Polyps associated with underlying infected
chronic sinusitis are more likely to have associated sinus
