We describe a novel measurement of cranial morphology in pre- and post-operative scaphocephalic patients to complement the cephalic index. This will better describe restoration of normal skull and head shape, further defining the nuances of the corrected skull. In this retrospective comparative study the location of the euryon on the skull was statistically significantly different in preoperative scaphocephalic patients versus non-scaphocephalic controls. This difference was resolved with surgical cranial vault remodeling, indicating restoration of a normal skull profile. Additional measurements of the location of the euryon in relation to the forehead prominence, combined with validated cephalic index measurements, can further describe postoperative outcomes in scaphocephaly. More sensitive clinical measurements such as these can aid the craniofacial surgeon in assessing outcomes in cranial vault remodeling. Further, large-scale study is needed to determine if additional anterior skull metric points may be useful in documenting skull shape restoration.

OBJECTIVEMetrics used to quantify preoperative severity and postoperative outcomes for patients with sagittal synostosis include cephalic index (CI), the well-known standard, and the recently described adjusted cephalic index (aCI), which accounts for altered euryon location. This study tracks the time course of these measures following endoscopic repair with orthotic helmet therapy. The authors hypothesize that CI and aCI show significant regression following endoscope-assisted repair.

Background: Preoperative severity and postoperative success for patients with sagittal synostosis are measured by cephalic index, but this metric does not describe the appropriateness of euryon location. The authors hypothesize that cephalic index in patients with sagittal synostosis is an inaccurate measure of scaphocephaly.
Methods: Preoperative and 1-year postoperative cranial computed tomographic scans of children with sagittal synostosis treated before 6 months of age by either total calvarial reconstruction or endoscope-assisted craniectomy and helmet therapy (n = 10 for each) were reviewed retrospectively.

Background: Earlier studies have addressed the human total cranial vault thickness and generally found no correlation with sex, age or body weight. However, the thickness of the diploe has not been investigated. Our study has determined the diploeic thickness of the human cranial vault using modern autopsy material.
