Presentation on Cochlear Implantation by Prof. George Tavartkiladze,English

  1. 1. Presentation of Prof. George Tavartkiladze in St. Petersburg at the 1st Monsana Conference (May 2009) The first part of the presentation is dedicated to neonatal hearing screening. The speaker explains the different methods of hearing screening used in clinics and emphasizes the necessity to perform neonatal hearing screening before mother and child leave the hospital. It is the task of paediatricians to perform a hearing screening on all newborns and to do the necessary further tests in case of hearing disorders to be able to give a precise diagnosis. A rehabilitation programme needs to be defined before the age of 6 months. The decision of the right method of treatment is of special importance. A treatment will be most successful if it already starts in the first months of the baby’s life. Parents need to be advised how they can and should communicate with their child that is most probably hearing impaired or deaf. After the diagnosis suitable hearing aids should be fitted bilaterally. This is already possible from the 6th month of life. The following three months will show if it makes sense to use hearing aids. If the use of hearing aids does not bring satisfactory results, the child can be a candidate for a cochlear implant. Prof. Tavartkiladze also speaks about the different varieties of hearing prostheses. • Surgery (prosthesis) • Electroacoustic correction • Cochlear Implantation Prof. Tavartkiladze further elaborates on the issue of cochlear implantation. In many cases the cochlear implant is the most promising choice for the treatment of deafness. He presents the possibilities of the technology, explains the criteria for the choice of patients, describes the examination before the surgery, why magnetic resonance imaging is necessary, which are the contraindications of a Cochlear Implant and possible complications that might result. In the second part of his presentation Prof. Tavartkiladze tells about the current status of development of diagnosing hearing disorders in newborns. Statistics show that 1 of 1.000 babies is born deaf; two develop deafness within the first two years of their life and 20 to 40 newborns have various hearing disorders. Early detection, diagnosis and intervention are an absolute precondition for achieving best possible results. Therefore it is that important to discover these problems by means of hearing screening. The different methods of hearing screening and modern diagnostics are explained. The third part of the presentation is dedicated to the cochlear implant as the most efficient method of treatment of hearing impairments. Prof. Tavartkiladze explains the factors which can influence the prognosis of success of a CI for patients. Different varieties of electrodes are shown and it is explained how a CI works. New research models of the CI were presented, especially a new concept for an electrode. Also the issues that still require a solution are not forgotten: • Broadened indications for the use of a CI • Binaural Implantation • Hybrid-fitting of CI and hearing aid (bimodal Stimulation) • Sources for financing In the end Prof. Tavartkiladze speaks about new research areas in Otology, especially about genetic therapy and the application of stem cells.
