In patients with unilateral condylar hyperplasia, increased length of the condylar neck causes deviation of the mandible to the opposite site, resulting in facial asymmetry, but the arch form and general contour of the displaced mandible is approximately symmetric. So, the unilateral condylectomy have been prefered surgical method among the surgeons. The purpose of this study is to analyze the postoperative results comparatively following two different surgical methods, condylectomy and ramus surgery, in unilateral condylar hyperplasia. Case of 6 patients with the unilateral condylar hyerplasia were analyzed in this study, 3 case of the condylectomy only, 3 cases of the ramus surgery, Clinical and radiographic evaluations were tried for comparison. In conclusion, comparative results between two groups did not show any significant difference, but we confirmed that unilateral condylectomy could be a excellent surgical methods in unilateral condylar hyperplasia thinking over the unique morphological characteristics of it.

This is a case report and review of literature of the facial asymmetry corrected by various surgical methods. In case 1, facial asymmetry resulted from osteochondroma of condyle and corrected via condylectomy only. In case 2, unilateral condylar hyperplasia with compensatory maxillary growth resulted in severe facial asymmetry. Procedures used in case 2 are vertical ramus osteotomy, condylectomy, genioplasty, mandibular inferior border ostectomy and Le Fort I osteotomy.

In patients with unilateral mandibular condyle hyperplasia, whether to perform condylectomy and orthognathic surgical procedures at the same time or orthognathic surgery in two stages for remains controversial. Reported here is a case of facial asymmetry with mandibular condyle hyperplasia, for which condylectomy and orthognathic surgery procedures were performed at the same time. A 28-year-old woman was presented to our department with chief complaints of left deviation of the mandible and right temporomandibular joint (TMJ) noise. Findings obtained in several imaging examinations led to a diagnosis of facial asymmetry associated with right mandibular condyle hyperplasia. Following 3 months of preoperative orthodontic treatment, in October 2018 under general anesthesia the patient underwent a right mandibular condylectomy, Le Fort I osteotomy, right mandibular sagittal split ramus osteotomy, and left mandibular inverted L ramus osteotomy. In examinations up to 3 years after surgery, good results were noted. For this case of severe facial asymmetry with mandibular condyle hyperplasia, early surgery and condylectomy were performed simultaneously to significantly shorten the total treatment time. The effectiveness of a surgery-early approach was confirmed by no postoperative findings indicating abnormalities in the TMJ or retroversion.

Classification of facial asymmetry has not been yet well-organized because of their variety on etiologic factors, involved sites and clinical expressions. And surgical treatments are also variable and depend upon their causes and clinical abnormalities. This is a case report on surgical experiences of two patients who had severe facial asymmetry and could not treated pre-surgical orthodontics before surgery. One patient was belong to hemifacial microsomia and another was a very unusual complex type related to unilateral condylar hyperplasia, unilateral macrognathia and unilateral mandibular hypoplasia. The authors used a simultaneous two-jaw surgery, bone shaving and onlay-type bone graft in former case, and a simultaneous two-jaw surgery, condylectomy, bone shaving and only-type bone graft in latter case. In two cases, immediate post-operative results in function and esthetics were excellent, however, progressive resorption of onlay-type bone grafts have been noticed.
