Bimaxillary osteotomies in correction of dentofacial deformities.
In 342 patients with dentofacial deformities cephalometric analyses were preoperatively performed. A study of occlusion on cast models as the simulated new position of the facial soft tissues was done on the photographs. Surgical treatment using bimaxillary osteotomies for correction of dentofacial deformities was done in 38 patients: 31 with prognathism and maxillary hypoplasia, 5 with facial asymmetry and laterognathism and in 2 with otomandibular dysostosis. The LeFort I type osteotomy was used for the upper jaw and Obwegeser technique for the lower jaw. Intermaxillary and circumzygomatic immobilization were removed 8-10 weeks after the operation. After that, the patients retained the individual chin traction from 2 to 3 months. The complete relapse occurred in one patient and prolonged loss of the mandibular nerve sensibility in one.
