The method of intraoral oblique sagittal splitting oseotomy, a new modification of the sagittal splitting osteotomy, is presented. This procedure is distinct from Obwegeser-Dal Pont method in the following two points; 1. Horizontal osseous incision is made through the cortex medially, extending just only posterior and superior to the lingula. 2. Lateral bone cut is performed down the anterir border of the ascending ramus along the external oblique ridge directly to the inferior border of the mandible with slight oblique direction to the sagittal plane, not extending to the second molar.<BR>Thirty-two mandibular prognathism patients with or without anterior open bite have been corrected by this procedure. The advantages of this technique are reduction of operating time, less blood loss and fewer complications. This osteotomy is indicatd for mandibular prognathism with less than 15mm set back required.
