This is a case of skeletal class III malocclusion with facial asymmetry, gummy smile, and maxillary canting, treated with bimaxillary surgery and orthodontic treatment. The two-jaw surgery was performed including a 3-pieces LeFort I segmental osteotomy, anterior segment impaction with clockwise rotation, and bilateral sagittal split osteotomies with genioplasty. Through the 2-year-4-month treatment procedure, the skeletal and occlusal relationship turned to be normal with esthetically pleasing smile and profile. Furthermore, in the two-year follow-up, we found the treatment results were quite stable no matter in skeletal or dental aspects.
