Endoscope-Assisted Versus Open Repair of Craniosynostosis: A Comparison of Perioperative Cost and Risk

Background: Craniosynostosis, the premature closure of calvarial sutures, results in characteristic skull deformations. Correction of craniosynostosis has traditionally involved an open cranial vault remodeling procedure. A technique recently developed uses an endoscope to perform a strip craniectomy in conjunction with a postoperative molding helmet to guide cranial growth. Few studies compare these 2 approaches to the treatment of the various forms of craniosynostosis. In this study, we present a single institution's experience with open cranial vault remodeling and endoscope-assisted strip craniectomy. Methods: This study is a retrospective review of 57 patients that underwent craniosynostosis repair by either the endoscope-assisted or open techniques, and compared operating room times, blood loss, volume of transfused blood, length of hospital stay, and overall costs. Results: The endoscopic technique is performed on younger children (4.7 months vs 10.6 months, P = 0.001), has shorter operating room times (2 hours 13 minutes vs 5 hours 42 minutes, P = 0.001), lower estimated blood loss (74.4 mL vs 280.2 mL, P = 0.001), less transfused blood (90.6 mL vs 226.9 mL), shorter hospital stays (1.2 days vs 4.9 days, P = 0.001), and decreased cost ($24,404 vs $42,744, P = 0.008) relative to the traditional open approach. Conclusions: Issues with the endoscope-assisted procedure primarily concerned the postoperative helmet regimen, specifically patient compliance (17.1% noncompliance rate) and minor skin breakdown (5.7%). The endoscope-assisted repair with postoperative helmet molding therapy is a cost-effective procedure with less operative risk and minimal postoperative morbidity. This is a valuable treatment option in younger patients with compliant caregivers.
