[Cochleography and cochlear view as the way of assessment of successful surgical inner ear implantation].
115 cochlear implantation were performed in ENT Department Karol Marcinkowski University of Medical Sciences in Poznań in 1994-2001. Nucleus Mini System 22 and Nucleus 24 of Cochlear Ltd were used in these operations. Two approaches were performed: middle fossa approach in one case and traditional one. The aim of this study was evaluation of cochleogram and cochlear view as the ways of assessment of successful inner ear implantation. One of X-ray projection were performed in implanted patients 24 hours after implantation. In cochleograms the degree of electrodes rotation in cochlea was calculated. The number of inserted electrodes in cochlea was calculated in cochler view projection. Described X-ray projection were performed in 70 patients. On X-ray projection (cochleograms) rotation degree of electrodes in majority were equal or higher than 250 grades (according to literature it is sufficient for successful speech rehabilitation). X-ray projection--cochlear view confirmed full insertion of electrode.
