Plagiocephaly is the term loosely applied to frontal or posterior cranial asymmetry. Deformational plagiocephaly is the most common form. Synostotic frontal plagiocephaly is usually sporadic, but can be syndromic or familial. These two major categories of plagiocephaly are distinguishable by physical findings. Deformational plagiocephaly tends to self-correct during infancy; this process can be ameliorated by conservative measures. Synostotic frontal plagiocephaly requires surgical correction during infancy.
