Endoscopic-assisted strip craniectomy (ESC) with orthotic molding therapy provides a minimally invasive alternative to open fronto-orbital advancement. Herein, we describe a 3D photogrammetry methodology for measurement of regional cranial growth and inter-frontal angle (IFA) as well as examine factors that may contribute to successful outcomes after ESC. Methods: A retrospective review was performed on patients with MC treated with ESC and band therapy from 2015 to 2019. Patients obtained 3D photogrammetry preoperatively, postoperatively, and post-helmet therapy. A survey was administered to 14 independent raters, who were asked to determine treatment success based on subjective visual assessment of preoperative and post-banding images. Patients were considered to have successful therapy when ≥75% of raters were in agreeance. Results: Thirteen patients met inclusion criteria. Average age at s...

These primary defects cause a secondary alteration of the craniofacial skeleton. Current therapies do not attempt to correct the cranial base deformity in childhood. Another cause of oblique deformities of the skull is deformational plagiocephaly. This common disorder is secondary to external deformational forces and tends to improve with time and may require only conservative treatment. Method: We present two cases of deformational plagiocephaly superimposed upon hemifacial microsomia. Orthotic treatment was utilized to improve both the deformational plagiocephaly and the cranial base deformity. Conclusion: This novel therapy has the potential to correct the cranial base deformity in craniofacial microsomia. Descriptors: Skull/abnormalities. Facial asymmetry. Orthotic devices. Plagiocephaly. Orthotic treatment in patients with craniofacial microsomia and deformational plagiocephaly

METHODS: A database of >20000 children treated for DP was examined by using 2- and 3-way factor analyses for categorical frequency data, representing the largest statistical analysis of DP to date. Data on parity, zygosity, intrauterine presentation, birth number and weight, sleep position, lateralization, and sex were collected from parents of children with DP who were treated at Cranial Technologies, Inc, from 1990 to 2007. RESULTS: As with most DP studies, male patients were significantly overrepresented. Nonetheless, after statistically accounting for sex in our analyses, DP is significantly correlated with primiparity, fewer vertex but more breech and transverse intrauterine presentations, twinning (spe...

Also, the condition typically lateralizes to the RS of the occiput.
