[A study of maxillary and mandibular vasculature in relation to orthognathic surgery].
Angiography and Chinese ink perfusion were performed in 14 cadavers. It was found that the origins of arterial blood supply to maxilla and mandible in human beings are multiple. Normally, the maxilla and mandible receive not only the centrifugal blood from the alveolar arteries, but also the centripetal blood from the surrounding mucoperiosteum. This feature of jaw bone's blood supply is the important anatomic basis for the establishment of blood compensation to the moved bone segments which are nourished only by attached mucoperiostea after osteotomies have cut off the blood supply of alveolar arteries in orthognathic surgery.
