[The dynamics of the blood supply to the maxillary complex following a maxillary osteotomy].

Regional maxilla hemodynamic changes were studied in 40 patients. After surgical correction of combined upper jaw deformations, the osteotomized fragment showed sufficient blood flow which originated from distal maxilla blood vessels. By 45 days after surgery the blood flow reached its preoperative level. More pronounced changes were detected in the regional blood flow in patients with combined jaw deformations after congenital labial, soft and hard palate clefts. In these patients, retardation of the blood flow restitution could reflect the scarification of the tissues of soft and hard palate, and lips.
