Infracture technique for reduction malarplasty with a short preauricular incision.

The infracture technique for reduction malarplasty has been widely used as an aesthetic surgical procedure in northeast Asia. Since 1988, the authors' original method of infracture technique was performed through the combined approach of intraoral and temporopreauricular incision, which may leave a rather long scar on the temporal region. To shorten the external scar, a new technique using a short preauricular incision instead of a long temporopreauricular incision was developed. From September of 2000 to June of 2001, this new approach was applied to 142 patients for correction of prominent zygoma. In this procedure, anteriorly, incomplete fracture of the zygomatic body was performed through an intraoral approach for bending inward. Posteriorly, full-thickness cutting of the zygomatic arch was performed through a preauricular incision. Then, lateral bulging of the zygomatic arch was reduced with infracturing, and the infractured site was fixed in a new position with a microplate and three screws. The advantages of this technique are reduction of the operation time, reduction of the length of the external scar, and reduction of postoperative edema around the operative region. With this combined approach, the authors were able to sufficiently expose the zygomatic arch and body and able to change the lateral convex arch into a concave one. Under direct vision, the authors could effectively and precisely perform the infracture technique through a much shorter preauricular incision that did not result in a long, conspicuous external scar.
