[The evaluation of nasal ventilation in allergic rhinitis patients after nasal provocation].
OBJECTIVE
To evaluate nasal ventilation in allergic rhinitis patients after nasal provocation with acoustic rhinometry.


METHODS
Twenty AR cases were selected. Each one was assessed for the nasal cavity volumes (NCV), nasal airway resistance (NR), nasal minimal cross-section area (NMCA) and distance of nasal minimal cross-section area from nostril (DCAN) by using acoustic rhinometry before and after nasal provocation 1 hour and 6 hours later. The results were statistically analyzed.


RESULTS
After nasal provocation 1 hour 1 later, NCV and NR had a significant difference compared with before nasal provocation(P<0. 05), but NMCA and DCAN had no difference (P > 0.05). After 6 hours later, NCV, NR, NMCA and DCAN had a significant difference compared with before nasal provocation (P < 0.05). NCV,NR,DCAN had a significant difference between 1 hour later and 6 hours later after provocation (P < 0.05), while NMCA had no difference (P > 0.05).


CONCLUSIONS
The nasal ventilation in allergic rhinitis after nasal provocation had declined over time.
