Quantification of Bilateral Coronal Synostosis: Anterior Brachycephaly

Abstract

Objectives: Very few studies focus on the quantification of severity of synostotic anterior brachycephaly. Aim of this study is to implement Utrecht Cranial Shape Quantifier (UCSQ) in brachycephaly patients to objectively quantify severity for both clinical and research purposes. Design: Retrospective study. Setting: Primary craniofacial center. Patients and Participants: Fifteen preoperative patients with bilateral coronal craniosynostosis (age <1.5 years). Intervention: Utrecht Cranial Shape Quantifier was used to quantify severity using the variables: width of frontal peak ratio, difference forehead peak and occiput peak, and width between sides of the head. Main Outcome Measure(s): The UCSQ variables were combined and related to Argenta clinical classification and cephalic index (CI) using 1-way analysis of variance (ANOVA). All parameters were derived from computed tomography scans. Results: Statistically significant differences were found between group means of UCSQ in the 3 categories of Argenta (ANOVA; F(2,12) = 22.461; P
