It can be felt easily with palpation and may influence the appearance of the patient negatively. This article presents a procedure osteotomy designed to modify the osteotomy lines at the lateral orbital rims and smooth the step deformity at the lateral canthal region. Results The seesaw osteotomy produced a smooth contour at the lateral orbital rim. Planned advancement was achieved without difficulty and without adverse long-term effects.
