Endoscopic release of unicoronal craniosynostosis

We demonstrate a novel method of endoscopic frontal-orbital advancement for the treatment of unicoronal craniosynostosis. The evolution of this cranioplasty modality burrows from an established precedent of safety and technical experience in strip craniectomies and endoscopic brow surgery. The procedure facilitates osteotomies similar to open frontal-orbital advancement and uses reabsorbable materials to achieve immediate intraoperative correction of unicoronal craniosynostosis through smaller incisions. The patients in the study underwent endoscopic frontal-orbital advancement and cranial vault remodeling. This was made possible with the use of a novel ultrasonic bone saw that permits osteotomies to be made with minimal disruption to the dura matter. After full frontal-orbital advancement, immediate reabsorbable fixation was used to stabilize the advancement as in the open technique. There were no major complications. All patients demonstrated improvement in plagiocephaly due to unilateral coronal synostosis. Patients and their families reported a 100% patient satisfaction and an improvement in cranial asymmetry from 10 to 2 mm (P < 0.5). This is a new endoscopic cranial vault remolding technique that achieves state-of-the-art correction of unicoronal craniosynostosis with less morbidity and mortality.
