Binaural cochlear implantation after bilateral temporal bone fractures.
In this clinical note we discuss the indications, feasibility, and outcomes of binaural simultaneous cochlear implantation (CI) following bilateral transverse temporal bone (TB) fractures. A 41-year-old male, totally deaf after a bilateral TB fracture, underwent an audiological, electrophysiological, and imaging investigation in order to assess the integrity of the VIIIth cranial nerves. Five months later he received a simultaneous bilateral CI. Speech perception tests were conducted at different time points. A significant advantage by dichotic listening was observed since the beginning of the habilitation program. The patient achieved a 100% word and sentences recognition in quiet at 12 months. His listening skills in noisy conditions were improved by the use of two implants. A CI in TB fractures is feasible if the VIII nerve is intact and the cochlea is spared by the fracture rim. The early timing of the procedure probably contributed to its success by preventing cochlear fibrosis and ossification.
