Secondary Sequels (Congenital Muscular Torticollis)

Drawings of the contours of the head from the top during torsion to the left (left figure) and in straight position (right figure). As a secondary sequel of congenital muscular torticollis with preferred torsion of the head to the left in right-sided congenital muscular torticollis (predominant torsion by the normal contralateral left-sided sternocleidomastoid muscle), there is a parieto-occipital flattening on the left side. This positional plagiocephaly shows a bald head or diminished growth of hair at the site of flattening and may be combined with a contralateral frontal plagiocephaly.
