New horizontal v-shaped osteotomy for correction of protrusion of the zygoma and the zygomatic arch in East Asians: indication and results

Protrusion of the zygoma is commonly considered undesirable and unattractive among East-Asians, and many try to achieve a harmonious oval midface by having various cosmetic operations. However, effective contouring for a severe protruding zygoma has rarely been reported .The objectives of this study therefore were to investigate the feasibility and effectiveness of a horizontal V-shaped ostectomy for correction of protrusion of the zygoma and zygomatic arch, and to discuss its indications. From January 2008 to December 2011 we treated 27 patients by contouring of the zygoma with a horizontal V-shaped ostectomy through intraoral and preauricular incisions. The effectiveness was then evaluated with cephalometric radiographs, 3-dimensional computed tomography, and standard facial photographs taken before and after operation. The postoperative appearance of all 27 patients showed that the protrusion had been effectively reduced with no serious complications, and the facial contour had improved. The final aesthetic outcomes were satisfactory for both surgeons and patients. The horizontal V-shaped osteotomy is a good technique for the reduction of protrusion of the zygoma and zygomatic arch, and it has the advantages of more convenient multishifting, better results, and fewer complications. It also ensures the integrity of the structure of the malar complex.
