Multimodal Outcomes of Early Open Extended Midline Strip Craniectomy With Bilateral Microbarrel Staving for Correction of Isolated Nonsyndromic Sagittal Synostosis.

ABSTRACT

AIM: Sagittal synostosis is the most common craniosynostosis. The aim of surgery is to preserve cognitive function and to correct the morphologic changes. In our unit, the authors offer strip craniectomy and microbarrel staving (SMB) performed at 16 to 22 weeks. This study aims to ascertain the 7-year outcome of scaphocephaly correction by SMB. The authors investigate whether the improvement in cranial index (CI) is sustained over time, and report speech and language and neurodevelopmental outcomes. METHODS: All nonsyndromic patients with sagittal synostosis who underwent SMB between 2009 and 2012 were identified from a prospectively created database that recorded anthropometric measurements, quality metrics, and neurodevelopmental outcomes. RESULTS: A total of 27 patients were analyzed. The mean CI preoperatively was 67.5% (±3.5), and at 7 years 78% (±4.8). Regarding neurodevelopmental outcomes at 7 years, SDQ responses did not highlight any concerns for social, emotional, or behavioral outcomes. The vast majority of those who completed a WASI-II assessment performed within the average ranges in terms of cognitive ability. In terms of speech and language 70% of subjects demonstrated receptive language within normal level (WNL). Seventy-seven percent of subjects demonstrated expressive language WNL. CONCLUSIONS: In conclusion, after 7 years of follow-up, early open extended SMB is a safe and effective method for correction of isolated nonsyndromic isolated sagittal synostosis. Across the neurodevelopmental measures and assessments, the children in the current study appeared to perform within expected ranges. Speech and language problems are more prevalent than in the general population.
