ObjectiveTo observe the effect of coronary balloon dilation eustachian tuboplasty combined with the catheterization of tympanic tube membrane in the treatment of recurrent secretory otitis media.MethodsFortynine patients (64 ears) with recurrent secretory otitis media were retrospectively analyzed and followed up regularly at 1 month, 3 months and 6 months after surgery. The 49 cases were divided into three groups(group A,B and C). The patients of group A is a experimental group(n=16, 22 ears) , who were received eustachian tube balloon dilation combined with tympanotomy tube insertion. The B and C groups are control. The patients of group B were received only eustachian tube balloon dilation(n=16, 21 ears),while the patients of group C received only the catheterization of tympanic tube membrane(n=17, 22 ears). All eustachian tube dilatation were done by coronary artery balloon. The 7item eustachian tube dysfunction questionair (ETDQ7), acoustic immitance and eustachian tube score (ETS) were completed for evaluating the efficacy of the stated treatment.ResultsEustachian tube function of the patients was improved in three groups at 1 month, 3 months and 6 months after surgery. Type A tympanogram was gradually increasing after the tympanic membrane healing. At 6 months after surgery, ETDQ7 scores were lower in the group A than in the control B, C groups, and ETDQ7 scores of the control group C were lower compared to that of the group B. At 3,6 months after surgery, ETS scores were higher in the group A than in the control B, C groups, and ETS scores of the control group C were higher compared to that of the group B.ConclusionFor recurrent secretory otitis media caused by eustachian tube dysfunction, eustachian tube balloon dilation combined with with the catheterization of tympanic tube membrane can significantly improve clinical symptoms. It is an effective surgical intervention for treatment of secretory otitis media.The coronary balloon is cheaper than the conventional eustachian tube balloon and has the same therapeutic effect in the treatment of secretory otitis media.
