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).
Conclusion:
The alveolar cleft plays an important role in the maxillary aberration.
