title: [Effect of surgically induced bilateral cleft alveolar on maxillary growth in dogs].
abstract: OBJECTIVE
  To establish an animal model of bilateral alveolar cleft and to determine the effect of cleft on maxillary growth.
  
  
  METHODS
  Eight dogs (12 weeks old) were divided into unoperated control groups (n = 4) and the model group (n = 4). The model dogs were operated to establish a bilateral alveolar cleft. All the dogs were killed and the craniofacial morphology on clean skull was analyzed by the direct detection and CT.
  
  
  RESULTS
  The length, the foreside width, and the foreside height of the maxillary in the model group were shrunken compared with those of the control group (P < 0.05).
  
  
  CONCLUSIONS
  The alveolar cleft plays an important role in the maxillary aberration.
