Our Auditory Implant Program 1992 The first cochlear implantation (H. Skarżyński) 1998 The first auditory brainstem implantation (Warsaw, Wuerzburg, Innsbruck) 2003 The first middle ear implantation (H. Skarżyński) 2005 The first bilateral cochlear implantation 2006 First direct stimulation of the round window membrane (H. Skarżyński) 2008 The first bilateral auditory brainstem implantation 2009 New concept of PDT (H. Skarżyński) MANAGEMENT IN PDT A. GROWING EXPERIENCE 1992 2010 > 3000 hearing implants
MANAGEMENT IN PDT A. GROWING EXPERIENCE ROUND WINDOW APPROACH was a challenge: a) at the first Cochlear Implantation b) at presentation of the first results and experiences in residual hearing preservation - 5th ESPCI - Antwerp 2000 Skarżyński H., Lorens A., Piotrowska A.: Residual acoustic hearing in the ear before and after cochlear implantation c) at the PDT in adults (2002) and in children (2004) Skarzynski H., Lorens A., Piotrowska A.
