ABSTRACT
Objective:
To estabish an animal model with blast injury in maxillofacial region and to study the biomechanical property of the model.Methods:
Spherical explosive at different distances was used to make wound in maxillofacial region in dogs. The pressure on tissue at different level, the variation of horizontal acceleration and strain of the mandibular and temporal bone were dynamically measured.Results:
About 3.5 cm?3.0 cm soft tissue defect and madibular splintered fracture occurred in maxillofacial region when the spherical explosive exploded on the surface of the dog's face and the animal survived. The pressure on mandible was respectively 3.6%?2.9% of the surface of dog's face when the spherical explosive exploded 0 and 1.00 cm away from the dog's face while the ratio of horizontal acceleration of cranium to mandibular was 1/8?1/6. Splintered fracture occurred in mandible when the mandibular strain was 11 375 ??.Conclusion:
The model can be applied as an animal model with blast injuries in maxillofacial region.
