The evaluation of nasal ventilation in allergic rhinitis patients after nasal provocation / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To evaluate nasal ventilation in allergic rhinitis patients after nasal provocation with acoustic rhinometry.@*METHOD@#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.@*RESULT@#After nasal provocation 1 hour 1 later, NCV and NR had a significant difference compared with before nasal provocation(P 0.05). After 6 hours later, NCV, NR, NMCA and DCAN had a significant difference compared with before nasal provocation (P 0.05).@*CONCLUSION@#The nasal ventilation in allergic rhinitis after nasal provocation had declined over time.
