The aim of this rapid assessment is to summarise the information on the relative effectiveness and safety of balloon Eustachian tuboplasty (BET) for the treatment of Eustachian tube dysfunction (ETD) in a population aged over 12 years. The comparators included tympanostomy tubes (grommets) and medication (such as nasal decon-gestants, simethicone, oral or nasal corticosteroids, antibiotics, antihistamines, leukotriene receptor antagonists).
For effectiveness, the primary outcome was normalisation of tympanometry measures indicating normal ear and other measures related to functioning of the middle ear (Valsalva manoeuvre, tube score, otoscopic findings, audiometric evaluation of hearing function). In addition, quality of life, need for additional treatments, and long-term effectiveness were studied. Adverse effects (e.g. early complications, serious adverse events) were also studied.
