Spring-mediated cranioplasty (SMC) offers durable correction for sagittal craniosynostosis, showing sustained long-term improvement in cranial index. Further research is needed to optimize SMC and adjunct therapies.

Area of Science:

  • Neurosurgery
  • Pediatric Surgery
  • Craniofacial Surgery

Background:

  • Sagittal craniosynostosis is a common condition requiring surgical intervention.
  • Spring-mediated cranioplasty (SMC) is a minimally invasive technique for treating sagittal craniosynostosis.

Purpose of the Study:

  • To describe the surgical technique for SMC.
  • To evaluate the long-term morphometric outcomes of SMC for sagittal craniosynostosis.

Main Methods:

  • Retrospective review of patients undergoing SMC for sagittal craniosynostosis (2011-2019).
  • Analysis of demographic variables, perioperative data, spring characteristics, and cranial index (CI).
  • Longitudinal CI changes assessed using mixed-effects models; comparison of 2 vs. 3 springs using Mann-Whitney U tests.

Published on: August 11, 2015

Main Results:

  • Seventy subjects included; 74% received springs only, 26% also had post-operative helmeting.
  • Mean pre-operative CI was 0.67; mean post-operative CI at >10 years was 0.76 (non-helmeted) and 0.74 (helmeted).
  • No significant difference in CI change between 2 or 3 springs, despite different forces; regression indicated force varies with spring number.

Conclusions:

  • SMC provides durable and sustained long-term correction of sagittal craniosynostosis, evidenced by improved cranial index.
  • Further research is required to identify predictors of CI change and the role of adjunct therapies like helmeting.
