ORL Danube Society is an association of ENT specialists from the Danube countries (Germany, Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova and Ukraine), which was founded in 2018. The statutory activity of the association is the integration of physicians and scientists from the Danube region and organization of conferences to exchange knowledge and develop otorhinolaryngology.

Prof. Piotr H. Skarżyński has collaborated with the Danube countries for many years, conducting screening in different countries, such as Romania and Moldova, training activities or being involved in consortia applying for joint EU grants for scientific projects. In July 2019, by decision of the ORL Danube Society authorities, Prof. Piotr H. Skarżyński was appointed Honorary Member of the association.

The next scientific symposium organized by the association will be held in Budapest in 2022.
