Safety of radiofrequency ablation for adenotonsillectomy after cochlear implantation

We found that radiofrequency ablation used in the oropharynx during adenotonsillectomy did not alter the integrity of the cochlear implant devices when assessed using electrode impedance testing, audiometry and speech perception evaluation. These results confirm those reported in previous in vitro studies and confirm the safety of radiofrequency ablation adenotonsillectomy for children who have undergone previous cochlear implant placement.
