[Abstract]:Objective to establish a standard animal model of maxillofacial blast injury and to study the damage characteristics of the temporomandibular joint disc. Methods the microsphere explosive was used as an explosive source from the rabbit face to detonate at different distance from the rabbit face. The animal model of the maxillofacial blast injury was established, and the injury was observed immediately after the injury, 6 h and 1D were observed, and the transmissive lens of the temporomandibular joint was cut through the injured side. The transmission of the injured side of the temporomandibular joint was carried out. Results the animal model of the maxillofacial blast injury established by the experiment was repeatable, stable, more close to the wartime explosion damage, the edema of the temporomandibular joint disc, the disorder of the fiber arrangement and the focal dissolving. Conclusion the model is a typical model of trauma, and it is widely applicable; the temporomandibular joint can play a great role. Mechanical buffering can slow down craniocerebral injury to a certain extent.
