The Intraoperative Analysis of SONATATI100 Cochlear Implantation / 听力学及言语疾病杂志

ABSTRACT

Objective Using maestro software to analyze the application of electrically elicited stapedius reflex and auditory nerve response in assessing acoustic function intraoperatively .Methods 20 SONATATI100cochlear im-plant patients participated in this study .Both ESRT and ECAP were recorded intraoperatively by using MED -EL Maestro software and analyzed .Results 96 .67% typical ESR and 95 .0% typical ECAP were recorded .Certain properties of ECAP recordings varied depending on the stimulation sites in the cochlea .There was strong relation-ship between ESRT and ECAP thresholds .Conclusion ESR and ART were proved to be most beneficial in assessing the functions of the implanted as well as proving that the auditory pathway is stimulated during the cochlear implan-tation surgery .
