“…Should the implantation be delayed for a longer period of time, should the condition of the cochlea be followed by radiological methods or should the ear be reimplanted and electrode fixed in the mastoid cavity with a titanium clip 25 . For prudence of failure, it was decided to implant the opposite ear in both cases, although only modest functional results were expected 26 . Both patients have been followed for three years and no complications were observed.…”

Aim: To present two cases of late complications of cochlear implantation. Case report: In both cases extracochlear extrusion of the implant electrode occurred. More than ten years after successful cochlear implantation, the hearing performance gradually worsened to the point of no intelligibility in both patients. Otomicroscopy revealed chronic otitis media (COM) with an electrode in the external ear canal in implanted ears of both patients. Extracochlear electrode extrusion was noticed on CT scans in both cases. In the first case the device was explanted, the electrode was left in the cochlea and tympanoplasty was performed. Regardless the normal status of the middle ear, extracochlear extrusion occurred again. Conclusion: After extracochlear electrode extrusion, the reimplantation is likely to be unsuccessful. Sažetak. Cilj:Prikazati dva slučaja kasnih komplikacija kohlearne implantacije. Prikaz slučaja: U oba slučaja radilo se o ekstrakohlearnoj ekstruziji elektrode umjetne pužnice. Više od deset godina nakon implantacije u oba pacijenta sluh je postepeno slabio do potpune nerazumljivosti. Otomikroskopijom je u oba pacijenta utvrđena kronična upala uha uz prisutnost elektrode u zvukovodu. Učinjena je kompjutorizirana tomografija koja je potvrdila ekstrakohlearnu ekstruziju elektrode. U prvom slučaju učinjena je eksplantacija umjetne pužnice, pri čemu je elektroda ostavljena u kohleji te timpanoplastika. Usprkos urednom cijeljenju uha, ekstruzija elektrode se ponovila. Zaključak: Nakon ekstrakohlearne ekstruzije elektrode velika je mogućnost da će reimplantacija biti neuspješna.

“…One of the factors that may be important for cochlear implant (CI) success in bilateral sequential cochlear implantation is the time interval between implantations. It is well-known that a long inter-implant delay between implants leads to poor speech perception and auditory performance in children with bilateral sequential cochlear implants (BSCI) [10][11][12][13]. When they listen with their second CI, weaknesses in auditory behavioral performance have been observed, as well as prolonged P1 responses [14][15][16].…”
