A case of mandibular prognathism with slight open bite is reported in this paper. The patient, a 21-year-old girl, was referred for the correction of mandibular prognathism. Intra-oral examination revealed an anterior cross bite with overjet at -1 mm and slight open bite. Cephalometric analysis was made and the patient was ultimately diagnosed as skeletal class III malocculusion. Since single operative method seemed difficult to provide a successful outcome, a combinational surgical correction consisted of sagittal splitting osteotomy according to Obwegeser-Dal Pont's method of the right mandibular ramus and stepostectomy using modified Dingman's method in the left side of the mandibular body was performed. In consequence, a sufficient result was obtained with favorable prognosis.
