Resumo
Background: Le Fort III osteotomy represents the main technique for midface hypoplasia correction in syndromal and non-syndromal patients in order to improve midface advancement and achieve better aesthetic and functional results.
Objectives: To present a treatment of a nonsyndromic male patient with severe midface hypoplasia, concave profile and Class III malocclusion treated with Le Fort III surgery in association with Le Fort I advancement osteotomy followed by mandibular repositioning.
Methods: The treatment initiated with presurgical orthodontic alignment and further orthognathic surgery with both Le Fort I and Le Fort III advancement and mandibular repositioning to correct mandibular asymmetry.
Results: The maxilla moved forward and downward and midface projection improved. The mandible anteroposterior relationship was maintained, the laterognathism was corrected and an orthognathic profile and Class I occlusal relationship were achieved.
Conclusions: Development of the simultaneous Le Fort III and Le Fort I osteotomy technique improved stability and facial aesthetics, increasing its indication for nonsyndromic skeletal Class III patients with severe midface deficiency.
