To date, more than 130 000 Balloon Eustachian Tuboplasty (BET) procedures have been performed worldwide. This procedure is proposed in case of Obstructive Eustachian Tube Dysfunction (OETD) with or without chronic otitis media. However, the effectiveness of this procedure is still discussed amongst otolaryngologist. Most of studies,were open label prospective studies comparing Eustachian tube function before and after surgical treatment. A recent meta-analysis suggests that BET procedure improves postoperative Eustachian tube function, but high-level evidence is still lacking. In this project, the investigators propose to perform the first blinded randomized controlled trial procedure to assess the changes of Eustachian tube function after BET in a population of subjects with chronic OETD with or without chronic otitis. Prognosis factors of efficacy will be also investigated during the study.
