title: [Cochlear implantation with pericanal electrode insertion technique].
abstract: OBJECTIVE
  To investigate the surgical technique of the pericanal electrode insertion technique for ies cochlear implantation.
  
  
  METHODS
  Forty cases of sensorineural deafness were subjected to the ies cochlear implants. Cochleostomy was performed through the external auditory canal with a microdrill anterior to the round window. The electrode impedance and electrically auditory brainstem responses(EABR) were tested during the operation. The X-ray photographs were taken after the operation. The cochlear implant was activated in all 40 cases 4 weeks following surgery.
  
  
  RESULTS
  All of the electrodes were inserted and all of the implants worked well. No electrode extrusions or serious surgical complications happened during postoperative observation for 6 months.
  
  
  CONCLUSIONS
  The pericanal electrode insertion technique is a safe approach for ies cochlear implantation.
