title: Auditory Nerve Recovery Function in Cochlear Implant Surgery with Local Anesthesia and Sedation versus General Anesthesia.
abstract: To analyze auditory nerve recovery function (REC), comparing the results after local anesthesia and sedation with those after general anesthesia.
  
  
  
  This was a prospective, cross-sectional and descriptive study in a tertiary referral center hospital. We included all patients (37 ears) who underwent surgery for cochlear implant under either general anesthesia or local anesthesia and sedation during 3 years. REC was measured according to the function of 3 components, 'T0', 'A' and 'tau', and was taken for 3 cochlear electrodes (apical, medial and basal).
  
  
  
  There were no significant differences in 'tau' and in the current level used, but there were significant differences in the parameters 'T0' apical and 'A' basal.
  
  
  
  There were no significant differences in REC between the 2 types of anesthesia, except for the parameters 'T0' apical and 'A' basal.
