title: [The location of inserting the electrode into the cochlear].
abstract: OBJECTIVE
  To determine the position of implanting electrode into the scala tympani.
  
  
  METHODS
  The analogous operation of cochlear implantation were made in 50 temporal bones and the anatomic data were measured after the operation.
  
  
  RESULTS
  The position of implanting electrode is 2.77 mm below the vestibular window and 0.85 mm anterior to the round window.
  
  
  CONCLUSIONS
  It suggests that this anatomic parameter provide a reference value to determine the position of cochlear implant electrode into the scala tympani.
