«Pterygo-clivus triedre»: three dimensional analysis of stability or variations during growth

M.M Rousset, H Blocquel, S Reboul, A Taleb-Ahmed, J.P Dubus

Abstract


The growth’s study, from skull’s radiographics, needs the use of superposition’s structures. Three X ray radiographics pictures from the front, from profile and from under are retalling by a soft. This orthogonazilation’s step has been realized for every child at two different ages. The reconstruction of the «clivus» straight and «pterygoïde» straights from three views gives the « pterygo-clivus triedre» which stability is studied for time.
