Minimally Invasive Strip Craniectomy for Sagittal Synostosis

Abstract

The most common approaches used today for the correction of sagittal synostosis involve large craniectomies and extensive cranial vault remodeling. Although these techniques ultimately yield very good cosmetic results, they have significant drawbacks. They are lengthy, expensive, associated with significant blood loss, universally require transfusions, and often result in prolonged hospitalization.We present here our 5-year experience with correction of sagittal synostosis using the recently described minimally invasive strip craniectomy followed by postoperative cranial vault helmet molding. During this period, we treated a total of 97 children with nonsyndromic single-suture synostosis. The first 46 of 67 children treated for sagittal synostosis had at least 1 year of postoperative follow-up and were included in the analysis. There were 33 boys and 13 girls. Patients' mean age at surgery was 3.1 months, and the mean weight was 6.1 kg. The mean operative time was 75 minutes. The estimated blood loss during the procedure was 56 mL. Eight patients received blood transfusions during surgery (17.4%) and 3 patients received after surgery (6.5%). There were no significant postoperative complications. The mean hospitalization was 2.2 days. Excellent aesthetic outcomes were noted in all patients. The change in cranial index from a preoperative value of 0.7 to 0.8 postoperatively was virtually stabilized 3 months after the surgical intervention. Significantly better correction rates were observed in the youngest patients.Because of its excellent attributes, minimally invasive strip craniectomy followed by postoperative helmet molding is likely to become the preferred treatment modality for the correction of sagittal synostosis.
