Orthognathic surgery associated with joint prosthesis in the treatment of facial asymmetry: case report

The asymmetric growth of the face may be triggered by skeletal congenital, genetic or traumatic as a result of injuries and fractures that impair mandibular growth. The correction of mandibular asymmetry aims to achieve, simultaneously, improve aesthetics and prevent jaw function, too, the recurrence of such a deformity. The cases of facial asymmetry are not easy to fix and do not always involve only the mobilization of a segment. However, an important part of orthognathic surgery. This study reports a case of mandibular asymmetry, exposing the possible causes for this deformity and the type of surgical treatment offered to order corrective surgery concomitantly. The diagnosis of these deformities should be based on anamnesis, dental and medical history prior clinical and radiographic examination, analysis models, bone age and, in specific cases, and other complementary tests such as bone scans.

When degenerative diseases, among others, affect the TMJ, one of the therapeutic is the complete replacement of components by a system of joint prosthesis. Through the concepts of coxofemoral orthopedic prostheses and dental implants osseointegrated system was designed a prosthesis that consists of an TMJ card with a prosthetic condyle installed in the mandibular cortical screws and secured by a capsular component set in the zygomatic arch, which may osseointegrated and be replaced in the future if necessary.
