Summary

The information about the position of the implant after cochlear implantation is very important for the surgeon and the entire rehabilitation team. Cone-beam CT (CBCT) is a special type of computed tomography (CT), which provides better imaging with a lower radiation dose on a small area of the cochlea. The aim of the paper is to inform the professional public about the introduction of this imaging method in Czechia. In the ORL Dept. University Hospital Hradec Králové, CBCT has been performed on 31 devices in 30 users of cochlear implant of all three CI manufacturers available in the Czech Republic. Selected parameters were evaluated and their results are discussed. CBCT is a standard at foreign implant centres and its introduction in the Czech Republic is a logical step towards improving the care of implant centres. The teamwork of ENT doctors, examining stomatologist, interpreting radiologist and rehabilitation team is important for a correct examination process. Optimum of the imaging in the future will be perioperative CBCT in the operating room, which can only be used to verify the position of the electrode array in all patients immediately after insertion and eventually to reposition it.
