Subcranial Le Fort III Advancement with Equine-Derived Bone Grafts to Correct Syndromic Midfacial Hypoplasia: A Case Report.

Patients with hypoplasia of the midface normally present a flattening of their facial profile due to insufficient development of the nose and maxilla. Treatment aimed to restore function and an aesthetic appearance calls for a Le Fort III osteotomy and the advancement of the midfacial segment either through distraction or interposition of autogenous bone blocks. However, drawbacks in using autogenous bone suggest that use of alternative graft material may be advisable.
