Application of Le Fort Ⅲ osteotomy with minimal invasive approach in the treatment of midfacial hypoplasia

Abstract

To describe a minimal invasive approach in the Le Fort Ⅲ osteotomy procedure. 33 cases with midfacial hypoplasia were treated by Le Fort Ⅲ osteotomy.Incisions were performed with minimal invasive approach,through lower eyelid,intraoral and upper eyelid crease or medial part of eyebrow instead of coronal incision.After the completion of osteotomy,distraction osteogenesis or orthognathic procedures were followed. The midfacial segments achieved enough advancement without obvious relapse.Bleeding and operative time were reduced compared with coronal approach.No obvious scar was left. The Le Fort Ⅲ osteotomy procedure could be successfully performed through minimal approach with steady results and minimal scars.
