Orthognathic Surgery in Skeletal Class l Patient with Facial Asymmetry

The purpose of this case report was to describe the considerations in surgical orthodontic treatment of a patient with skeletal Class I malocclusion and facial asymmetry. A 22-year-old male presented with a chief complaint of facial asymmetry. Clinical examination showed severe facial asymmetry to the right side at his chin point. Also he showed lip canting and straight facial profile. Intraorally, he exhibited posterior crossbite in the right side with severe mandibular dental midline deviation to the right. After presurgical orthodontic treatment with dental decompensation was done, sagittal split ramus osteotomy (SSRO) with mandibular body shaving was done to correct the mandibular asymmetry. After orthodontic treatment, posterior crossbite and midline of the dentition was corrected, and asymmetry of the mandible was improved. For the patient with facial asymmetry, it is critical to eliminate dental compensation orthodontically and to move the teeth to their proper positions to avoid relapse and obtain stability.
