Die marginale Schnittführung in der orthognathen Chirurgie des Oberkiefers

From 1/1994 to 12/2000 the marginal gingival incision was chosen as surgical access to the maxilla for performing mono- and bimaxillary orthognathic surgical procedures with and without segmentation in a total of 274 patients. Sufficient perfusion of all segments could be verified by clinical measures (fresh punctuate bleedings from the bony surface) in all cases during surgery. Ten days after surgery there were 12 cases (4.4%; n=274) of isolated partial papillary necrosis. There were no infections or wound dehiscences. In a follow up examination of 100 patients with a recall intervall between 4 and 71 months 14% (n=100) had visible gingival retraction. After staining with Schiller' lodine solution the measured width of the gingiva was found to be similar to that stated in the periodontological literature. Probing with a PCP12-probe resulted in pocket depths above three millimeters at one or more teeth in 80% of cases as well as papillary bleeding was found in 80% of patients.
