Geometric considerations when planning an asymmetric genioplasty

Nadejda Stefanova, DMD/John Paul Stella, DDS

The sliding osteotomy of the inferior border of the mandible otherwise known as genioplasty, has often been described in the world literature with regard to diagnosis and treatment planning. However, the treatment of the asymmetric chin has received little attention. Moreover, diagnosis and treatment planning of asymmetric chins with concomitant orthognathic surgery is completely lacking from the literature. The complexity of surgically correcting asymmetric chins, compounded with complex, bimaxillary orthognathic surgery, is an extremely challenging task. This article looks at geometric considerations when planning the surgical correction of an asymmetric chin following a protocol of data collection, model surgery, diagnosis, and treatment planning. Clinical experience in the form of a case presentation will demonstrate the minute precision that can be achieved when planning corrective genioplasty in a asymmetric patient undergoing concomitant orthognathic surgery.
