Otovent opens the eustachian tube and allows the fluid that has been collected in the middle ear to drain naturally down the back of the throat. The Otovent procedure can be performed at home under the supervision of parents. The treatment takes only a matter of seconds to perform and is painless. Otovent should be used 2-3 times daily for a period of 2-3 weeks. Otovent balloons should be changed every 3 days. Otovent should not be used during a cold, ear, or throat infection. Note! maximum 20 inflations per balloon. Non-returnable item after opened or used.When the balloon is inflated to a grapefruit size the technique is correct and therefore optimum benefits from the treatment will be gained. You will know that the treatment works if you experience a pressure increase and/or a "pop" in the ear. If the ear does not “pop” upon inflation, the patient should swallow as the balloon deflates back through the nasal passageway.
