Combined Le Fort I osteotomy and oblique sliding osteotomy of the mandibular rami. A follow-up.
Bimaxillary surgery involving mandibular set-back and maxillary advancement has been performed on eight patients with severe prognathic mandibles and in two patients with pronounced retropositioning of the maxilla. The combined surgical approach turned out to give a very satisfying result both from the functional and aesthetic points of view. Whereas a certain skeletal horizontal relapse occurred in the mandible and a vertical one in the maxilla, the occlusal stability was maintained in all but one case. A good postoperative occlusion obviously retains the teeth in position. The soft tissue adaptation and final configuration postoperatively takes a long time, and should if possible be subjected to more sophisticated analysis before surgery. The bimaxillary approach with step-wise surgery, using an intermediate wafer is, in our opinion, a good solution to marked malpositions and in many cases preferable to single jaw surgery.
