[The relationship between perennial allergic rhinitis and chronic sinusitis].
OBJECTIVE
To observe the incidence rate of chronic sinusitis in the patients with perennial allergic rhinitis, and explore the possible etiology of sinusitis.


METHODS
Fifty-seven patients were examined with endoscope and CT scan.


RESULTS
Of the 57 patients, 18 (32%) patients had chronic sinusitis, among which 17 patients had different kinds and different extents of anatomy abnormalities of nose cavity including deviation of nasal septum, concha bullosa, hypertrophy of uncinate process, paradoxical curvature of middle turbinate, etc. Thirty-nine patients didn't complicated with chronic sinusitis, among which only 7 patients had anatomy abnormalities of nose cavity.


CONCLUSIONS
Anatomy abnormalities of nose cavity may be the basic etiology of sinusitis in patients with perennial allergic rhinitis; The edema of nasal mucous and the change of nasal discharge caused by perennial allergic rhinitis may be the triggering factor of chronic sinusitis. Both of these two factors are involved in the pathogenesis of sinusitis.
