Abstract 29. To Operate or Not?: Surgical Decision-making Concerning the Spectrum of Orbitofrontal Deformity Associated with Metopic Suture Closure

Purpose: Metopic suture closure can manifest from benign metopic ridge, a benign variant of normal, to “true” metopic craniosynostosis (MCS), a severe trigonocephaly. Currently, there is no gold standard for how much associated orbitofrontal dysmorphology should trigger surgical intervention. In our study, we used a semi-automated three-dimensional (3D) curvature analysis to separate the phenotypes along the spectrum, and have employed it in conjunction with cluster analysis to compare surgeons1 thresholds for operation at one tertiary care craniofacial center
