Abstract：Objective To evaluate the effect of autogenous bone graft of intraoral approach and preauricular small incision in malar nonunion after zygomatic osteotomy.Methods From January 2015 to December 2017,9 patients with malar nonunion after zygomaric osteotomy for prominent malar complex were treated in our department.All patients were treated by autogenous bone graft by using a malar bone,outer mandibular plate,or iliac bone.Titanium plates and titanium nails were used for internal fixation.Results All zygomatic bone and zygomatic arch fractures were well healed,and transplanted bone were well survived postoperatively.The patients were followed up for 3 to 24 months,during which time no serious complications occurred.The appearance was satisfactory.There was no visible scar on the face.Conclusion Excessive osteotomy,improper alignment,and poor fixation are the main causes of nonunion of the zygomatic bone and zygomatic arch.Autogenous bone graft combined with rigid internal fixation is an effective and safe method for the treatment of malar nonunion after zygomatic osteotomy for prominent malar complex.
