title: [Observe the dissection of the tunnels of augmentation rhinoplasty under endoscope].
abstract: OBJECTIVE
  To observe and analyse the dissection of the tunnels in traditional blind operation of augmentation rhinoplasty.
  
  
  METHODS
  11 Cases of augmentation rhinoplasty were collected and be observed by an endoscope as soon as the tunnels were formed during the operations.
  
  
  RESULTS
  (1) Some of the tunnels did not go through one layer. (2) The bilateral cartilage separated in the mid-line. (3) There were two blood vessels in the surface of alar cartilage. There were perforating blood vessels in the edge of pyriform aperture. (4) In some cases whose incision were in unilateral alar margin, the tunnel were asymmetric.
  
  
  CONCLUSIONS
  In some cases of traditional blind operation of augmentation rhinoplasty, tunnels were not suitable, they were asymmetric; and there were desmo and septa in the tunnels. Those might be the causes of complications post-op of augmentation rhinoplasty.
