Lambdoid craniosynostosis. A 3D-computerized tomographic approach.

Abstract

From a series of eleven children aged from 4 months to eight years presenting with a parieto-occipital flattening that was unilateral in nine and bilateral in two, we attempted to determine a 3D-CT semeiology able to demonstrate the presence of a lambdoid suture synostosis, as well as the participation of coronal and lambdoid sutures in the genesis of complex cranial malformations. Pure isolated forms of lambdoid synostosis are rare and justify a surgical treatment for cosmetic purposes if the deformation is severe and progressive.
