[A safe technique of Le Fort I osteotomy in bilateral cleft patients]. / Une technique sûre d'ostéotomie de Le Fort I chez les patients porteurs d'une fente labio-alvéolo-palatine bilatérale.

Le Fort I osteotomy is often needed in bilateral cleft patients. The usual approach to the maxillae may compromise the premaxillary vascularisation. We present a subperiosteal exposure preserving two paramedian vascular pedicles that respect premaxillary blood-supply.
