title: [Virtual endoscopy evaluation of congenital aural atresia].
abstract: OBJECTIVE
  To value the virtual endoscopic visualization for preoperative assessment of congenital aural atresia.
  
  
  METHODS
  Twenty patients with congenital aural atresia underwent a high-resolution CT of the temporal bone with VE, 8 patients subsequently underwent congenital aural atresiaplasty. CT examinations of the temporal bone were carried out using spiral equipment and endoscopic 3D processing was carried out on a separate workstation equipped with a flying through program.
  
  
  RESULTS
  VE is valuable for the evaluation of stapes, malleus-incus complex, facial nerve (only the tympanic portion), incus-stapes joint, round window niche, middle er space, the VE assessment matches the operation exploration perfectly, coincidence rates were 87. 5%, 100%, 100%,75%, 100% and 100% respectively.
  
  
  CONCLUSIONS
  This image processing method can be used pre-operatively for assessment, the individual planning, and simulation.
