Background: Children with craniosynostosis have abnormal head shapes. Parents frequently ask whether the abnormal head shape will get worse with time. However, there is no information in the literature to indicate whether the deformity gets worse.
Objective: To assess the progression of cranial morphology in children with unoperated craniosynostosis.
Methods: A retrospective review of all children with unoperated sagittal craniosynostosis who were referred to the Craniofacial Clinic at the Hospital for Sick Children (SickKids) was conducted. Serial 3D photographs of patients with sagittal craniosynostosis who have not undergone surgical correction were included in the study. There were 14 cases included, with 9 males and 5 females. Ages at time of scans ranged from 3 months to 5 years of age (mean = 28.3 months, SD = 28.2 months). Nine patients had the first scan at age of <12 months. Multiple scans for each patient were sized for volume over time and compared with a normative skull database.
Results: The results of measuring skull volume changes over time revealed no significant difference from infants without craniosynostosis. Furthermore, there cranial index was stable over time in patients with craniosynostosis.
Conclusion: The severity of craniosynostosis does not worsen or improve with time. Parents having difficulty in deciding to proceed with surgical correction of craniosynostosis can be reassured that the skull deformity will remain stable with the growth of their child if they decide not to proceed with surgical correction.

Frontal Sinus Volume in Normocephalic Nonsyndromic Sagittal Craniosynostosis: A Comparative Study.
J Craniofac Surg
January 2025
Division of Plastic and Reconstructive Surgery, University of Mississippi Medical Center.
Purpose: This study aimed to investigate frontal sinus volume as a potential indicator of cranial compensatory growth in unoperated normocephalic nonsyndromic sagittal craniosynostosis (NNSC) patients compared with age-matched and sex-matched controls. Previous studies have suggested that frontal sinus volume is suppressed in unoperated craniosynostosis and may be an intracranial space conservation phenomenon.
Methods: Head computed tomographies (CTs) from 22 unoperated NNSC patients at our institution were utilized in this study and matched with age-matched and sex-matched control subjects.
Long-Term Outcomes of Regional Morphology in Spring-Assisted Surgery and Cranial Vault Remodeling.
Plast Reconstr Surg
February 2025
From the Departments of Plastic and Reconstructive Surgery.
Background: Spring-assisted surgery (SAS) and cranial vault remodeling (CVR) are widely used surgical techniques to correct sagittal craniosynostosis (SC). The authors evaluated changes in regional morphology of patients with SC who had undergone SAS or CVR, using the frontal bossing index (FBI), occipital bulleting index, vertex narrowing index (VNI), and scaphocephalic severity index (SCI) to capture differences in anterior protrusion, posterior protrusion, width restriction, and global dysmorphology, respectively.
Methods: Indices were measured on computed tomography and 3-dimensional photographs (n = 788) of 257 patients with SC from 2001 through 2022 who underwent SAS (n = 177) or CVR (n = 80).
Two-Year Progressive Cranial Changes Following the Melbourne Technique for Sagittal Craniosynostosis.
Cleft Palate Craniofac J

Department of Plastic Surgery, University of Texas Southwestern Medical Center, Dallas, TX, USA.
Objective: The Melbourne technique for total cranial vault remodeling aims to address all aspects of scaphocephaly in sagittal craniosynostosis. These features include anterior-posterior excessive length, anteriorly displaced vertex position, frontal bossing, vertex narrowing, and occipital bulleting. This study aimed to determine the progressive cranial changes that occur following the Melbourne technique for sagittal craniosynostosis.

Jansen metaphyseal chondrodysplasia (JMC) is an ultra-rare disorder caused by constitutive activation of parathyroid hormone type 1 receptor (PTH1R). We sought to characterize the craniofacial phenotype of patients with the disease. Six patients with genetically confirmed JMC underwent comprehensive craniofacial phenotyping revealing a distinct facial appearance that prompted a cephalometric analysis demonstrating a pattern of mandibular retrognathia.

Craniosynostosis, a condition marked by the premature fusion of one or more cranial sutures, exhibits diverse phenotypes. This study aims to advance the understanding of these phenotypes beyond the conventional 2-dimensional analysis by focusing on identifying indicators of increased intracranial pressure (ICP) such as bony thinning or irregularities in skull morphology. A retrospective review was conducted for all pediatric patients with midline craniosynostosis who presented to our tertiary academic center for evaluation.
