Abstract     Background: Cochlear implantation is a safe and effective method of rehabilitation profound deafness of child or adult, who derives insufficient benefit from amplification of hearing aids. The aim of this study was to evaluate reasons for reoperations in cochlear implant surgery. Patients and methods: In a ten-year period 139 persons with profound hearing loss underwent cochlear implantation. All of them received multi-channel devices. Patient's follow-up period ranged from 6 months to 10 years. Results: To data, 28 reoperations (20.1%) in cochlear implant surgery have been performed in 20 patients (three patients had two revision surgical procedures on the same ear and in one case we made 5 reoperations). The major reason for reoperation was a device failure (12 cases [8.6%]). Two of Them had direct trauma to the ceramic package of the receiver. The three cases (2.2%) of incorrect electrode positioning required a revision operation (in one case two times) to put it to their correct place. In two cases nylon-tie for fixation of the receiver was unbound and the receiver migrated anterioly. The implant package was tied to bone again. In two cases after surgery necrotic tissue over the receiver arose. Necrotic tissue was excised and rotational scalp flap used to cover the device. In one case a foreign body granuloma set onto the fixed tie of the receiver area above the implant. The nylon suture-knot had to be removed. In another case eight months after the implantation an onset of acute purulent mastoiditis occurred, and the mastoid was consequently treated with additional operative and antibiotic treatments. Conclusion: Reoperation in cochlear implant surgery is safe and technically feasible for continued auditory perception.
