This condition results in significant cosmetic deformity and can impede neurodevelopment, if left untreated. Currently, rates of craniometric change following minimally invasive surgery have only been examined for sagittal craniosynostosis. A better understanding of postoperative skull adaptations in other craniosynostosis subtypes is needed to objectively categorize surgical outcomes and guide length of cranial orthosis therapy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS<\/jats:title>\n                    <jats:p>Eleven patients with sagittal and 8 with metopic craniosynostosis treated using endoscopic strip craniectomy and postoperative helmet orthoses were retrospectively reviewed. Using semiautomated image analysis of top-down orthogonal 2D photographs, the following craniometrics were recorded before surgery and at postoperative visits: cephalic index (CI), cranial vault asymmetry index (CVAI), anterior arc angle (AAA), posterior arc angle (PAA), anterior-middle width ratio (AMWR), anterior-posterior width ratio (APWR), left-right height ratio (LRHR), sagittal Hu moment (Sag-Hu), and brachycephaly Hu moment (Brachy-Hu). These craniometrics were then normalized to photograph-based measurements of normocephalic patients and the rates of change between metopic and sagittal craniosynostoses were compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>Patients with sagittal craniosynostosis exhibited significantly lower CI, lower PAA, higher AMWR, higher APWR, lower Sag-Hu, and higher Brachy-Hu preoperatively compared to patients with normocephalic craniosynostosis. Patients with metopic craniosynostosis exhibited lower AAA and AMWR preoperatively compared to normocephalic subjects. Sagittal and metopic patients had a rapid initial change in normalized CI or AAA, respectively. Craniometric rates of change that significantly differed between metopic and sagittal patients were found in AAA (p &lt; 0.001), AMWR (p &lt; 0.001), and APWR (p &lt; 0.0001). Metopic patients had a prolonged AAA change with a significantly different rate of change up to 6 months postoperatively (median at 3 months = 0.027 normalized units\/day, median at 6 months = 0.017 normalized units\/day, and median at &gt; 6 months = 0.007 normalized units\/day), while sagittal CI rate of change at these time points was not significantly different.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>Patients with metopic craniosynostosis have a prolonged rate of change compared to patients with sagittal craniosynostosis and may benefit from longer helmet use and extended postoperative follow-up. Categorizing craniometric changes for other craniosynostosis subtypes will be important for evaluating current treatment guidelines.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/2021.7.peds21239","type":"journal-article","created":{"date-parts":[[2021,10,1]],"date-time":"2021-10-01T03:34:03Z","timestamp":1633059243000},"page":"66-73","source":"Crossref","is-referenced-by-count":7,"title":["Rate of craniometric change following suture release in patients with metopic and sagittal craniosynostosis"],"prefix":"10.3171","volume":"29","author":[{"given":"Nathan K.","family":"Leclair","sequence":"first","affiliation":[{"name":"School of Medicine, University of Connecticut Health Center, Farmington;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William A.","family":"Lambert","sequence":"additional","affiliation":[{"name":"School of Medicine, University of Connecticut Health Center, Farmington;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joshua","family":"Knopf","sequence":"additional","affiliation":[{"name":"School of Medicine, University of Connecticut Health Center, Farmington;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Petronella","family":"Stoltz","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Connecticut Children\u2019s, Hartford; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David S.","family":"Hersh","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Connecticut Children\u2019s, Hartford; and"},{"name":"Department of Surgery, UConn School of Medicine, Farmington, Connecticut"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan E.","family":"Martin","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Connecticut Children\u2019s, Hartford; and"},{"name":"Department of Surgery, UConn School of Medicine, Farmington, Connecticut"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Markus J.","family":"Bookland","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Connecticut Children\u2019s, Hartford; and"},{"name":"Department of Surgery, UConn School of Medicine, Farmington, Connecticut"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"6","key":"b1","series-title":"J Neurosurg Pediatr","first-page":"622","article-title":"A review of the management of single-suture craniosynostosis, past, present, and future","volume":"24","author":"Proctor MR","year":"2019","unstructured":"Proctor MR, Meara JG.
