Surgical approach in severe cases of maxillonasal dysplasia (Binder's syndrome)

Binder's syndrome or maxillonasal dysplasia is a malformation characterized by an extremely flat and retruded nose. Severe cases of the syndrome do also have a retrognatic maxilla often combined with an open bite deformity which demands a combined surgical solution with both maxillary osteotomy and secondary nose correction. The two-stage surgical procedure in the advanced cases of maxillonasal dysplasia has in our opinion been preferable to a Le Fort II osteotomy. Two cases with severe Binder's syndrome where the two-stage procedure has been performed will be presented and the surgical approach discussed.
