Politzerization, also called the Politzer maneuver or method, is a medical procedure that involves inflating the middle ear by blowing air up the nose during the act of swallowing. It is often performed to reopen the Eustachian tube and equalise pressure in the sinuses.
The procedure was derived from a medical experiment first performed by Ádám Politzer of Vienna that involved studying the air movement through the Eustachian tube by connecting a manometer to the external auditory canal meatus and another manometer in the pharynx. His first results on the technique were published in 1861 and he introduced a pear-shaped rubber air-bag for performing the procedure in 1863, which came to be known as a Politzer bag. This system was far more practical and less difficult for the patient than catheterizing the Eustachian tube and brought fame to Politzer.
A handheld, battery-operated device called the EarPopper that allows Politzerization to be performed at home was introduced to the United States market in September 2005. A manual balloon based device known as the Otovent is available in Europe.
