Trans-tympanic silicone plug insertion for chronic patulous Eustachian tube

Abstract

Insertion of the plug was possible in all except two ears, in which it failed because of a narrow tympanic orifice of the ET. In 11 ears of 10 patients, the plug was replaced by a larger one using the same approach to improve efficacy. Of the 42 ears in which the silicone plug was successfully inserted, 30 (71.4%) achieved relief from symptoms of PET without additional treatment. In > 60% of these cases, the symptoms of PET were well controlled with an aerated middle ear. The follow-up period ranged from 6 to 68 months (mean 38.9 months).
