RESUMEN
OBJECTIVE@#To investigate the behavior difference of allergic rhinitis with adenoid hypertrophy between study group and control group.@*METHOD@#One hundred and seventeen children diagnosed as allergic rhinitis with adenoid hypertrophy were enrolled in our study were divided into study group and control group. Forty-two children treated with local steroid nasal spray for two to three months and antihistamine were control group. Seventy-five children treated with endoscopic adenoidectomy and drug treatment were study group; All children' parents were inquired for their clinical presentation.@*RESULT@#No distinctive differences were found between the two groups (P > 0.05) in adenoid hypertrophy, accompanying nasal problems and clinical questionnaire scoring. Significant statistical distinction were found (P < 0.05) in snoring, sleep disturbance and frequent arousal, nasal obstructive moth-breathing, and recurrent respiratory tract infection between the two groups after three-month follow up.@*CONCLUSION@#Endoscopic adenoidectomy should be taken into account for allergic rhinitis with adenoid hypertrophy in children. Adenoidectomy would be useful for the improvement of behavior symptoms.
