Figure 2. Representation of positional plagiocephaly and true (synostotic) posterior plagiocephaly. (A) Positional plagiocephaly showing: absence of lambdoid suture stenosis, format of a parallelogram skull, ipsilateral compensatory frontal bossing, ipsilateral ear in an anterior position, as if it had been pushed. (B) True posterior plagiocephaly showing: presence of lambdoid suture stenosis, shape of a trapezoid, ipsilateral bulging in the mastoid region, contralateral compensatory frontal bossing, ipsilateral ear stenosis tends to be in a posterior position and downwards, as if the suture pulled it.
