The Eustachian tube is a channel between middle ear and nasopharynx that works with the large region channel valve. It ventilates the middle ear and balances the ear pressure. It is always closed and opens when it is necessary. Eustachian Balloon tuboplasty is the current treatment applied to the functional obstruction of the Eustachian Tube.

In eustachian tube obstructions, the middle ear cannot be adequately ventilated and a pressure builds up or fluid accumulates in the middle ear. This in turn causes a feeling of ear fullness, pain and hearing loss in the ear. If the Eustachian canal is not treated, it may cause collapse of the eardrum (tympanic membrane retraction), attachment of the eardrum to the middle ear structures, inward pocketing of the eardrum, persistent fluid in the middle ear and recurrent middle ear infections. In cases where the Eustachian tube is open more than normal, patients whose middle ear ventilation is disrupted in the opposite direction this time they hear their own speech and breathing, experience a feeling of fullness in the ear and experience frequent ear bursts. This function can be treated with a Eustachian balloon tuboplasty method. Balloon tuboplasty can be performed reliably in children over the age of four have eustachian disorders. Balloon tuboplasty can be successfully applied in children, especially in cases of recurrent ear fluid collection, recurrent ear tube insertions, and severe collapse of the eardrum despite the removal of the adenoid.
