Unilateral condylar hyperplasia can cause facial asymmetry, occlusal disturbance, functional and aesthetic problems. In order to better correct these problems, orthognathic treatment is the only option. Mostly, the surgery of excessive growth of one condyle includes 2-jaw orthognathic surgery, condyle osteotomy and genioplasty. In this case, a 20-year-old male patient affected by right condylar hyperplasia underwent a surgical treatment with high unilateral condylectomy associated to 2-jaw orthognathic surgery and genioplasty, as well as orthodontic treatment before and after surgery. Because of serious skeletal problems, the partial malocclusion were adjustmented after surgery, it is better to maintain periodontal health and more effective. Detailed digital diagnosis and careful clinical management throughout the treatment course can help to provide satisfactory aesthetic and functional outcomes after follow-up 24 months.
