Abstract
This case report describes a successful orthognathic treatment using a combination surgery; unilateral sagittal ramus osteotomy (USSRO) and unilateral intraoral vertical ramus osteotomy (UIVRO). A 23-year-old male patient showing skeletal class III malocclusion with mandibular asymmetry visited our orthodontic department. Characteristics of his facial asymmetry was translation of the mandibular dentition to the left side, without yawing or canting of both jaws. After pre-surgical orthodontic treatment, orthognathic surgery with LeFort I osteotomy in the maxilla and combination surgery in the mandible was performed (USSRO on non-deviation side and UIVRO on deviation side). After 18-month of overall treatment, facial appearance and malocclusion were improved. The combination surgery (USSRO + UIVRO) could be a predictable and better treatment option that overcome the limitations of conventional orthognathic surgery for skeletal class III malocclusion with asymmetry.
