Ultrasonography as first line imaging for the diagnosis of positional plagiocephaly.

Abstract

In the last years, numerous studies evaluated different tools for the diagnosis of positional plagiocephaly (PP). The purpose of this study was to evaluate ultrasonography (US) as a first line screening test of lambdoid sutural patency in child with PP and to compare our results with the literature. All consecutive patients who referred to our Institute from January 2016 to October 2017 with the suspicion of PP, were included in the study and performed US examination of the lambdoid sutures. A 3-6-month clinical follow-up was performed by a pediatric neurosurgeon or a pediatrician to confirm the diagnosis of PP. Thirty-five children performed US examination and in all cases the diagnosis of PP was confirmed. No cases of anticipated suture fusion were examined during this period. The concordance between US findings and clinical exam follow-up was 100%. Ultrasonography of the lambdoid sutures represents an ideal first-line screening test and reliable alternative to other diagnostic techniques for lambdoid sutural patency in child with PP, being radiation free, fast and cheap.
