Sagittal Synostectomy With Tension Band Sutures for Correction of Sagittal Craniosynostosis

BACKGROUND AND OBJECTIVES: Premature fusion of the sagittal suture is the most common form of craniosynostosis and can be treated using a variety of open or endoscopic approaches. Existing approaches have varying degrees of effectiveness. Open approaches, whether performed early or late, can be associated with significant blood loss and the need for transfusion. Endoscope-assisted approaches are minimally invasive but require months of postoperative helmet therapy to help remodel the skull. Implantation of springs or distractors requires a second operation for removal of the devices. Here, we present an alternative technique for early correction of sagittal craniosynostosis combining sagittal synostectomy with tension band sutures to remodel the skull without need for transfusion or helmet therapy. METHODS: We retrospectively reviewed the medical records of all patients treated for sagittal craniosynostosis using a synostectomy with tension band sutures at a single tertiary care institution. Data on patient demographics, operative factors, and postoperative course were collected. RESULTS: Thirty-four patients underwent the novel procedure. The median preoperative cephalic index was 68 and improved to 76 immediately postoperatively. The median blood loss was 10 mL while the operative duration was 112 minutes. No blood transfusions were needed. One small dural laceration was encountered that was promptly repaired. There were no postoperative complications. Patients presenting for follow-up visits showed continued improvement in head shape and cephalic index. CONCLUSION: A modified sagittal craniectomy with tension band sutures to remodel the skull is effective in achieving immediate correction of sagittal craniosynostosis. The correction remains durable over long-term follow-up. Importantly, the technique can be performed with minimal blood loss and reduces transfusion risk, operative time, and overall morbidity compared with traditional open approaches while avoiding the need for helmet therapy necessitated by endoscopic approaches.
