Résumé

BACKGROUND AND OBJECTIVES: Surgical correction of nonsyndromic craniosynostosis (NSC) aims to restore cranial shape. Reossification of bone defects is paramount for the best aesthetic prognosis. However, the literature on the quantitative evaluation of bone defects after NSC surgery is scarce. This study aimed to quantify and analyze the surface area of bone defects after NSC surgery and establish a threshold value for predicting persistent defects. METHODS: We conducted a systematic review and a prospective study of 28 children undergoing surgical treatment for NSC. We analyzed 426 defects on the first computed tomography scan (1 year postoperative) and 132 defects on the second computed tomography scan (4.6 years postoperative). Statistical analysis was performed using Spearman's rank correlation coefficient, Mann–Whitney–Wilcoxon rank-sum test, and Youden's J statistic. RESULTS: Our systematic review identified three studies reporting on bone defects' surface area and reossification rate. In our study, we found no statistically significant differences in the number or size of defects between sex or type of NSC. The threshold value for the surface area of bone defects above which there was a higher probability of persistent defects was 0.19 cm 2 (Youden point), with an 89.47 % probability of persistence. Defects with a surface area below 0.19 cm 2 had a considerably lower probability, only 15.07%, of persistence over time. CONCLUSION: Our study provides valuable quantitative data for managing bone defects after NSC surgery. Defects with a surface area above 0.19 cm 2 should be monitored with radiological imaging because of the risk of persistence. Our findings highlight the importance of developing robust and reproducible methods for the quantitative analysis of bone defects after NSC surgery.
