Politzerization

Under tubes blowing Tubendurchblasung also refers to the therapeutic attempt to open a closed Eustachian tube (Tube) by generating a positive pressure in the nasopharyngeal space ( tympanales ventilation problem). This resets previously preceded by a tube function test, which is understood to surveys, that the patency of the eustachian tube is checked. The goal of treatment is an approximation of the pressure relationships between air pressure and middle ear internal pressure. As contraindication applies, for example, an infectious rhinitis.

Method

The simplest method of generating an overpressure is the Valsalva maneuver ( pressing at holding one's nose and mouth closed ). When Politzer attempt is pressed with a rubber balloon air into the nose while the patient swallows. Since is closed at swallowing the palate, the air is forced into the tube. This Politzer balloon air can also be pressed in an inserted through the nose into the tube opening metal catheter.

The Valsalva maneuver is often used for pressure compensation, for example when flying or diving. From ENT physicians the tubes blowing is used for diagnosis and especially treatment of a middle ear effusion or Tubenkatarrhs ​​.

For outpatient therapy and treatment support or work safety during caisson construction by the patient can also Otovent ® system (brand name ABIGO Medical AB, Askim Sweden) are used.
