简要总结
In this study, patients with dysfunction of the eustachian tube will be included. They will be randomized to one of two treatment groups.
- balloon dilation of the eustachian tube or
- nasal saline Patients will undergo follow-up for one year and will be able to crossover to the treatment arm after three months
详细描述
Patients will eustachian tube dysfunction will be asked to participate in the study.
They will be randomized to one of two groups
group 1 - surgical dilation of the eustachian tube in general anaesthesia
group 2 - daily nasal saline spray, twice a day
Regular Follow up with Tympanogram and Questionnaire
