Abstract

Abstract : Abstract: There is no clear consensus for the optimal treatment of sagittal craniosynostosis; however, recent studies suggest that improved neurocognitive outcomes may be obtained when surgical intervention imparts active cranial expansion or remodeling and is performed before 6 months of age. The authors consider spring-mediated cranioplasty (SMC) to optimally address these imperatives, and this is an investigation of how helmet orthoses before or after SMC affect aesthetic outcomes. The authors retrospectively evaluated patients treated with SMC and adjunct helmeting for sagittal synostosis. Patients were stratified into 4 cohorts based on helmet usage: preop, postop, both, and neither. The cephalic index (CI) was used to assess head shape changes and outcomes. Twenty-six patients met inclusion criteria: 6 (23%) had preop, 11 (42%) had postop, 4 (15%) had preop and postop, and 5 (19%) had no helmeting. Average age at surgery was 3.6 months. Overall, CI improved from a mean 69.8 to 77.9 during an average 7-month course of care. Mean preoperative change in CI showed greater improvement with preop helmet (1.3) versus not (0.0), ( P = 0.029), despite similar initial CI in these cohorts (70.4 and 69.6 respectively, P = 0.69). Nonetheless, all patient cohorts regardless of helmeting status achieved similar final CIs (range 76.4–80.4; P = 0.72). In summary, preoperative molding helmet therapy leads to improved CI at the time of spring-mediated cranioplasty. However, this benefit does not necessarily translate into overall improved CI after surgery and in follow-up, calling into question the benefits of molding helmet therapy in this setting.
