title: [The classification and treatment of lamina papyracea blow-out fracture].
abstract: OBJECTIVE
  To investigate the classification criterion and the treatment of lamina papyracea blow-out fracture.
  
  
  METHODS
  A clinic analysis was made on 108 case with lamina papyracea blow-out fracture. According to the classification, different treatments were taken differently.
  
  
  RESULTS
  The classification of 108 cases were reported as follows: 71 cases were classified as level 1, 33 cases as level 2, 4 cases as level 3. There was no special treat-ment for 43 cases (level 1) who had no diplopia. 28 cases (level 1) who had symptom of diplopia were treated conservatively. Its cure rate was 92. 9% (26/28). Other 34 cases were operated. Among them, 33 cases were classified as at least level 2, 1 case who had no satisfactory curative effect with conservative therapy was classified as level 1. The cure rate was 88. 2% (30/34). The other 4 cases classified as level 2 or 3 who didn't accept operation were treated conservatively, the cure rate was 25% (1/4).
  
  
  CONCLUSIONS
  The classification of lamina papyracea blowout fracture facilitates the judgement of patient's condition and the selection of treatment. The transnasal endoscopic operation on serious lamina papyracea blow-out fracture cases produces a good curative effect.
