Asymmetry of the lower third of the face, almost accompanying the deformity of maxilla or malocclusion, is ordinarily treated with repositioning osteotomy of maxilla or sagittal splitting ramus osteotomy for the purpose of the correction of occlusion. However, facial asymmetry is not completely corrected with such procedure in some cases, having laterognathism, condylar hyperplasia or temporomandibular joint ankylosis, resulting in a poor esthetic condition. In such cases, straightening genioplasty is indicated commonly. However, a case with significant asymmetry affecting the lateral aspect of the mandibular body cannot achieve straightening with this procedure. Consequently, onlay bone graft or alloplastic material implant is indicated to correct the remaining mandibular asymmetry. Recently, we introduced a Proplast® chin implant in a case of severe mandibular asymmetry. This is a report of our experience concerning treatment. A nineteen-year-old woman with a chief complaint of mandibular asymmetry resulting from a unilateral condylar hyperplasia was referred to our department. Primarily, the treatment was done to decrease the degree of asymmetry of mandible with the procedure of sagittal splitting ramus osteotomy and the ostectomy of lower portion of excessive mandibular body. However, the deficit of the right mental region was still remaining. We implanted a Proplast® chin implant to correct this asymmetry and obtained good esthetic result without any clinical problems.
