Endonasal premaxillary osteotomy.

Abstract

In our hands, the endonasal premaxillary osteotomy is an improvement over the buccal sulcus tunnel and transpalatal techniques not only because of preservation of the blood supply but also because of improved visualization to the premaxilla. We have found the technique to be particularly useful in the bilateral cleft patient in whom the palate has been closed before Le Fort I osteotomy.
