WebApr 13, 2024 · In this study, cochlea implantation was performed in normothermic and hypothermic rodent cochlea. The hypothermic group showed significant hearing preservation in contrast to the normothermic animals. Furthermore, the hearing preservation could be linked to a preservation of the outer hair cells ( Tamames et al., 2016 ). WebNational Center for Biotechnology Information
