An innovative device to support Politzer manoeuvre

Politzer manoeuvre causes retrograde inflation of the middle ear by forcing air through the Eustachian tube. It has been proposed as nonsurgical treatment of middle ear with effusion, Eustachian tube dysfunction and negative middle ear pressure from elevation changes. Even if Politzer manoeuvre can be considered a classical technique, it is generally performed without any feedback about its correctness neither about qualitative evidence about its efficacy. In this paper we describe an innovative device, named OtoFree, specifically designed to support medical doctors during Politzer manoeuvre. OtoFree provides information about the correctness of the manoeuvre and also useful hints about the treatments results.
