Abstract

We report a case of intraoperative cochlear implant whose initial evaluation was normal. Normality was assessed by introduction oval window, neural response and intraoperative objectification of acoustic reflex. However, the objectification of the proper implementation in scala tympani, with conventional radiology, showed a surprising anomalous position which forced an immediate reimplantation with very good results. The purpose of this communication is to share our experience and always advise a practical, fast and radiographic method low cost, which allows assessment of the electrodes with respect to its position and integrity, during insertion of cochlear implants.
