OBJECTIVE
Objective differentiation between unilateral coronal synostosis (UCS) and positional posterior plagiocephaly (PPP) based on 3D photogrammetry according to Utrecht Cranial Shape Quantificator (UCSQ).
DESIGN
Retrospective study.
SETTING
Primary craniofacial center.
PATIENTS, PARTICIPANTS
Thirty-two unoperated patients (17 UCS; 15 PPP) (age < 1 year).
INTERVENTIONS
Extraction of variables from sinusoid curves derived using UCSQ: asymmetry ratio forehead and occiput peak, ratio of gradient forehead and occiput peak, location forehead and occiput peak.
MAIN OUTCOME MEASURE(S)
Variables, derived using 3D photogrammetry, were analyzed for differentiation between UCS and PPP.
RESULTS
Frontal peak was shifted to the right side of the head in left-sided UCS (mean -value 207 [192-220]), and right-sided PPP (mean -value 210 [200-216]), and to the left in right-sided UCS (mean -value 161 [156-166]), and left-sided PPP (mean -value 150 [144-154]). Occipital peak was significantly shifted to the right side of the head in left-sided PPP (mean -value 338 [336-340]) and to the left in right-sided PPP (mean -value 23 [14-32]). Mean -value of occipital peak was 9 (354-30) in left- and 2 (350-12) in right-sided UCS. Calculated ratio of gradient of the frontal peak is, in combination with the calculated asymmetry ratio of the frontal peak, a distinctive finding.
CONCLUSIONS
UCSQ objectively captures shape of synostotic and positional plagiocephaly using 3D photogrammetry, we therefore developed a suitable method to objectively differentiate UCS from PPP using radiation-free methods.

Review
Lesions of the paediatric cranial vault are diverse both in their presentation and aetiology. As such, they pose a diagnostic challenge to the paediatric neurosurgeon and neuroradiologist. In this article, we delineate the spectrum of paediatric calvarial pathology into four distinct groups: (1) lytic lesion(s); (2) focal sclerotic lesion(s); (3) diffuse cranial vault sclerosis; and (4) abnormal shape of the cranial vault. It is our aim that this more pragmatic, algorithmic approach may mitigate diagnostic uncertainty and aid the more accurate diagnosis of paediatric calvarial lesions.

BACKGROUND
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.
METHODS
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.
RESULTS
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%.
CONCLUSIONS
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.
