The Boston Method for Sagittal Craniosynostosis Correction: Technique Description and Early Outcomes

Area of Science:

• Neurosurgery
• Pediatric Plastic Surgery
• Craniofacial Surgery

Background:

• Sagittal craniosynostosis causes characteristic cranial deformities due to restricted transverse growth.
• Existing cranial vault remodeling techniques face challenges in controlled correction and volume expansion.
• The Boston Method utilizes a geometry-driven approach focusing on posterior vault remodeling.

Purpose of the Study:

• To evaluate the effectiveness and safety of the Boston Method for treating sagittal craniosynostosis.
• To assess morphologic correction using cephalic index (CI) measurements.
• To analyze perioperative and transfusion outcomes, including the impact of virtual surgical planning (VSP).

Main Methods:

• Retrospective, single-center cohort study of patients with nonsyndromic sagittal craniosynostosis treated with the Boston Method.
• Data collection included demographics, perioperative details, and postoperative imaging.
• Primary outcome: quantitative morphologic assessment via CI; Secondary outcomes: perioperative characteristics and transfusion data.

Main Results:

• Twenty patients were included; 55% utilized VSP.
• Mean CI significantly increased from 70.7 to 76.0 postoperatively (P<0.001).
• Observed consistent morphologic correction, including biparietal widening and occipital elevation, with no reoperations required.

Conclusions:

• The Boston Method is an effective, safe, and reproducible technique for sagittal craniosynostosis.
• It achieves consistent morphologic correction via geometry-driven posterior vault remodeling.
• The technique results in biparietal widening and occipital expansion/elevation while preserving anterior structures.
