Trial Outcomes & Findings for Treatment of Cranial Molding Deformities in Preterm Infants (NCT NCT02366936)

NCT ID: NCT02366936

Last Updated: 2024-04-15

Results Overview

CI was determined by calculating the ratio of the biparietal diameter (BiPD) over the occipitofrontal diameter (OFD). The BiPD is defined as the widest transverse diameter of the head. BiPD was measured from the most prominent lateral point on each side of the skull in the area of parietal and temporal bones. The OFD is defined as the diameter of the head from the most prominent midline point of the frontal bone (glabella) to the occipital protuberance. While various reported ranges exist for cranial molding norms, dolichocephaly was defined as a CI of \<76%. The normative CI range is 76-85% for prone and supine sleeping infants. CI = BPD/OFD x 100

Measure
Use of Tortle Midliner
This study will be an interventional, longitudinal study of 30 preterm infants using the Tortle Midliner. Tortle Midliner: The Tortle Midliner is a breathable, knit beanie with two support rolls to help position the infant's head in midline while supine. It can also be worn sidelying or prone. The design includes Velcro adjustments and tabs for nasal cannula and feeding tubes. It is compatible with some ventilation devices, nasal CPAP, X-ray, and bilirubin shades. The beanie is designed to prevent dolichocephaly and provide passive stretch to cervical rotators if head preference has developed. It comes in three sizes and can fit preemies weighing 500 to 2500 g.
