    Abstract:
    Secondary to the increase in deformational plagiocephaly a growing number of infants with cranial deformity present to craniofacial teams. Computed tomography (CT) is diagnostic, but uses ionizing radiation. The purpose of this study was to evaluate ultrasound as a screening test for the patency of cranial sutures in scaphocephaly and occipital plagiocephaly. The cranial sutures of 54 infants with this cranial deformity were assessed by ultrasound. Sutures were read as patent or fused if a hypoechoic gap could or could not be demonstrated between the hyperechoic clavarial bones, respectively. Seven children suffered from true craniosynostosis of either the sagittal or the lambdoid suture. In five cases the ultrasound findings were diagnostic for a fused suture, in two cases the results were inconclusive. Forty-seven infants presented with deformational plagiocephaly. Ultrasound examination demonstrated patent sutures in 45 cases and was inconclusive in two cases. Sonography of the cranial sutures is a good screening tool to distinguish fused from patent cranial sutures in scaphocephaly and occipital plagiocephaly and avoids the radiation exposure associated with CT examinations.
