Abstract

Introductions: 

Craniosynostosis is a condition where the cranial sutures close prematurely. It is influenced by both genetics and environment. This paper focuses on craniosynostosis in twins, which is an understudied area. It presents a case report of male identical twins and conducts a meta-analysis based on 34 articles to understand the factors affecting concordance in twins who have craniosynostosis. The study considers factors such as zygosity, gender, genetic syndromes, and the type of synostosis.

Material and methods: A meta-analysis was conducted on 105 twin pairs (210 patients) identified from studies carried out between 1963 to 2023. The eligible studies, based on PICO criteria, included case reports and case series focusing on twins with craniosynostosis. A systematic literature search was conducted on PUBMED and Mendeley platforms to gather data on gestational age, zygosity, genetic syndromes, affected sutures, and concordance.

Results: The report is about two identical twin brothers who had sagittal and metopic suture synostosis. They were treated successfully with cranial remodeling surgery. In a meta-analysis of 105 twin pairs (210 patients) , a total of 25.9% showed concordance. The study found a significant difference in concordance between monozygotic (45.3%) and dizygotic (7.3%) twins. The analysis also revealed that twins with scaphocephaly had a higher degree of concordance than those with trigonocephaly (46.7% vs. 18.9%, respectively). The study did not find any significant correlation between gender, the presence of genetic syndromes, and concordance.

Conclusion: This investigation highlights the complex interplay of genetic and environmental factors in craniosynostosis in twins. The higher concordance in monozygotic twins emphasizes the genetic basis. These findings validate existing literature and provide new insights.
