The stylohyoid ligament in Hurler syndrome and related conditions: comparison with normal children.
The stylohyoid ligament is seen on lateral radiographs of the neck to be normally calcified to some extent in approximately 25% of all children between ages 1 1/2 and 15. When it appears, the ossification pattern is a relatively thin configuration in 90% of children. In 8 out of 9 children with Hurler syndrome, the stylohyoid was calcified, and was thicker than in normal children. This finding illustrates the nature of the stylohyoid ligament as a bone analogue, and its participation in the skeletal deformation pattern of dysostosis multiplex.
