A prominent mandibular angle is considered to be unattractive in Asians because it gives the face a square, coarse, and muscular appearance. Mandibular angle ostectomy has been known to be effective and to satisfy both surgeons and patients. However, a narrow surgical field hinders direct view of the site, making a procedure that is rather difficult to perform. Despite thorough presurgical planning and attention, there can be many complications and unfavorable results. A 21-year-old woman with right condyle process fracture was referred to Kyung Hee University Hospital at Gangdong. The patient was previously treated with mandibular angle reduction surgery at a local clinic. Via an extraoral approach, the condyle process was replaced and fixed using 1 long metal screw and one 2 × 2 square metal plate. We overcame the condylar fracture caused by mandibular angle ostectomy with reasonable reduction of the right condyle.
