title: [The suborbital plane and the pterygoid-clivus trihedron: development during growth].
abstract: We use three X ray radiographics pictures for every child at two different ages and we make the orthogonalization's step. The orientation of the "D.S.O." straight in "3" is studied with the "pterygo-clivien tripod", stable superposition's structure during growth.
