title: [On the clinical application of spiral CT three-dimensional reconstruction of middle ear ossicles].
abstract: OBJECTIVE
  To investigate the CT virtual endoscopy (CTVE) shows the display method of the normal structure of the middle ear, and evaluation of middle ear disease, particularly in the value and significance of the connection status of the ossicular chain, established display ossicular chain and middle ear structure methods.
  
  
  METHODS
  Volume scanning with a spiral CT unit was performed in forty normal cases and thirty patients with suspected lesions of middle ear. Respectively, with Germany's Siemens (Siemens SOMATOM Sensation 16) spiral CT the Inner Ear scanner patients with axial scanning, reconstruction of the original image, the software selected Fly-through A, B, C the point approach CTVE imaging studies. Focus ossicular chain connection status, and chronic otitis media shown the results of surgery in exploratory image control.
  
  
  RESULTS
  Normal group CTVE in the hammer bone, incus promontory, facial nerve, the lateral semicircular canal display rate was 100%; stapes, the two arch of the display rate in three display levels, respectively, to 57.5%, 70.0%, 97.5%; round window, oval window was 90.0%, 93.0%, 97.5%. Ossicular injury, displacement, interruption, deletion, deformity in cases of otitis media, trauma, temporal bone malformations.
  
  
  CONCLUSIONS
  CTVE link relations between the three ossicles (such as interrupt, etc.) have a certain advantage. By choosing the appropriate approach, CTVE has a considerable advantage in the ossicles and their connections, relations as well as pathological state. By comparing CTVE in three different display levels,the technique of CTVE is considered to be an advantageous supplement of tomography.
