Objective To study the characteristics of eustachian tube function in allergic rhinitis(AR)and its correlation with nasal symptoms.To observe the changes of eustachian tube function in AR patients with eustachian tube dysfunction(ETD)before and after the subcutaneous specific immunotherapy(SCIT).Methods 25 healthy volunteers(the control group)and 50 AR patients receiving SCIT(the study group)were subjected to tubomanometry(TMM),7-item Eustachian Tube Dysfunction Questionnaire(ETDQ-7),and VAS scores of nasal symptoms(nasal congestion,itching,sneezing,and runny nose).Among them,24 AR patients with ETD underwent the same test again at 6 and 12 months after SCIT.Results The TMM score of AR patients was lower than that of the control group,and the ETDQ-7 score was higher than that of the control group,the differences were statistically significant(P<0.05).The nasal congestion symptoms of AR patients before SCIT were negatively correlated with TMM(r=-0.283,P=0.004),and positively correlated with ETDQ-7 score(r=0.395,P=0.005).AR patients with combined ETD showed a significant increase in TMM scores at 6 and 12 months after SCIT treatment compared to those before the treatment(P<0.05 or P<0.01).The ETDQ-7 score significantly decreased compared to those before the treatment(P<0.05 or P<0.01).Conclusion AR patients are often accompanied by ETD,and nasal congestion is related to ETD.SCIT can improve nasal symptoms and promote the recovery of eustachian tube function with the increase of time.
